What’s the most important thing business leaders or entrepreneurs need to be aware of?

“Leaders need to accept and understand what AI technology can do. I have lived through the internet boom and the initial AI comeback a decade ago in the form of machine learning. Both of these were waves of change in the IT industry that affected every aspect of our society and our lives. But I’ve never seen such a high speed of adoption as with generative AI. Even though the technology is young and not perfect, it is obvious that it fills a real need for most of us, individuals as well as businesses. Therefore, leaders must educate themselves in AI to learn the truth about its capabilities and risks. Use AI to solve a problem; do not invent a clever solution to a problem no one has. Be aware of the new risks that generative AI introduces, like hallucinations and toxicity, and allow use of AI accordingly for your own customers.” – Zorina Alliata, professor of responsible artificial intelligence, digital business & innovation at OPIT

Which industries do you predict will be most disrupted by AI in the next couple of years?

“The financial industry is always one of the first to adopt new technologies. Financial companies are already using generative AI for document processing, risk assessment, fraud prevention and algorithmic trading. Because of increased computing power, we also see AI growth in healthcare and life sciences for drug discovery and enhanced diagnostic procedures. Retail, education, logistics are also adopting AI at a high pace. Which industries will remain unaffected? None, really. Even in high-touch human professions like nursing, therapy, parenting, AI is a tool that can help. While not replacing the job entirely, the industry will change because the AI tools are changing the way the job is done.” – Zorina 

Are there any new business models emerging due to AI advancements?

“I think we will see more AI-as-a-service (AIaaS) offerings, where AI tools are built on top of large language models and offer specific capabilities. This is an area where there is a lot of innovation, and I’m excited to see this develop further. I already use AIaaS on a daily basis for better writing, research, creating videos and presentations, and code debugging.” – Zorina 

What are the biggest challenges for small businesses and start-ups in adopting AI technologies?

“A big risk is too much enthusiasm and optimism. Generative AI has been adopted at a great speed. When you first try it, it is amazing. It can write a whole paper in seconds. It can explain complex diagrams and concepts. It feels like the trusted assistant you always needed, but it’s important to remember that AI comes with risks. It’s one thing to write an AI service that recommends what movie you should watch next, and another thing to write an AI service that reads your X-ray and diagnoses if you have a tumour. These two applications of AI have very different risk thresholds. You need to plan your AI service or product to be appropriate for use and to minimise the risk for your customer. I’ve also seen start-ups that tried out an idea and are now planning to build a product out of it, without any understanding of what it takes to run AI services at scale. Having best practices implemented, a good operational foundation, governance and a clear operational model are all requisites for running any production systems, especially something as risky and fraught with unknowns as AI products are.” – Zorina 

Which ethical considerations should entrepreneurs keep in mind when integrating AI into their businesses?

“Some considerations when creating your risk strategy for AI include data privacy and security (ensuring responsible collection and use of customer data); transparency (being clear about how AI is used in products or services); fairness and bias (addressing potential biases in AI algorithms); job displacement (considering the impact on employees and planning for transitions); accountability (establishing clear responsibility for AI-driven decisions); and environmental impact (considering the energy consumption of AI systems).” – Zorina

How is AI changing customer expectations?

“Customer expectations have gone up significantly since generative AI enabled better interactions. Customers expect omni-channel communications, immediate responses, and predictive service. For those companies that still have fragmented data in several platforms and lack a cohesive customer journey, the learning curve will be steeper. The good news is, there are a lot of innovations in this area.” – Zorina 

What skills do you think entrepreneurs will need to succeed in an AI-dominated business world?

“Some skills that would be useful include:

• AI literacy: understanding the basics of AI, machine learning and data science.
• Data analysis & interpretation: ability to work with and derive insights from large datasets.
• Strategic thinking: identifying where AI can add value to business processes and products.
• Ethical decision-making: navigating the ethical implications of AI implementation.
• Adaptability & continuous learning: keeping up with rapidly evolving AI technologies.
• Human-AI collaboration: effectively working alongside AI systems.
• Soft skills: creativity, critical thinking, emotional intelligence and leadership will become even more valuable as AI handles more routine tasks.

As a leader, you are not required to write code or figure out the best way to deploy your model, but a high-level understanding of what AI can do will help you have meaningful conversations with your technical team and create AI products that are truly useful.” – Zorina

Finally, how will AI impact the workforce this year?

“There are several studies on this, such as the one the World Economic Forum (WEF) released this month about the status of work and the future of jobs. Some of the highlights are that AI and other technologies will continue to broaden digital access, with a first effect on increased demand for AI and data skills. The number of technology-related roles is the fastest growing, but frontline roles like farmworkers, delivery drivers and construction workers are predicted to see the largest growth. AI has evolved quickly to create images and videos, threatening the jobs of designers and movie producers. It was not what we would have predicted a few years ago. AI has a way of growing in unexpected ways, as we discover new paths of research and innovate ways to use it. I personally think it is hard to predict exactly where AI will go, and what will be the result of automating all routine tasks and behaving closer to humans. One thing we can be sure of is that people who understand AI and know how to use it will benefit from whatever new challenges are coming our way.” – Zorina

By Zorina Alliata

ALEXANDRIA, VIRGINIA – In recent years, artificial intelligence (AI) has grown and developed into something much bigger than most people could have ever expected. Jokes about robots living among humans no longer seem so harmless, and the average person began to develop a new awareness of AI and all its uses. Unfortunately, however – as is often a human tendency – people became hyper-fixated on the negative aspects of AI, often forgetting about all the good it can do. One should therefore take a step back and remember that humanity is still only in the very early stages of developing real intelligence outside of the human brain, and so at this point AI is almost like a small child that humans are raising.

AI is still developing, growing, and adapting, and like any new tech it has its drawbacks. At one point, people had fears and doubts about electricity, calculators, and mobile phones – but now these have become ubiquitous aspects of everyday life, and it is not difficult to imagine a future in which this is the case for AI as well.

The development of AI certainly comes with relevant and real concerns that must be addressed – such as its controversial role in education, the potential job losses it might lead to, and its bias and inaccuracies. For every fear, however, there is also a ray of hope, and that is largely thanks to people and their ingenuity.

Looking at education, many educators around the world are worried about recent developments in AI. The frequently discussed ChatGPT – which is now on its fourth version – is a major red flag for many, causing concerns around plagiarism and creating fears that it will lead to the end of writing as people know it. This is one of the main factors that has increased the pessimistic reporting about AI that one so often sees in the media.

However, when one actually considers ChatGPT in its current state, it is safe to say that these fears are probably overblown. Can ChatGPT really replace the human mind, which is capable of so much that AI cannot replicate? As for educators, instead of assuming that all their students will want to cheat, they should instead consider the options for taking advantage of new tech to enhance the learning experience. Most people now know the tell-tale signs for identifying something that ChatGPT has written. Excessive use of numbered lists, repetitive language and poor comparison skills are just three ways to tell if a piece of writing is legitimate or if a bot is behind it. This author personally encourages the use of AI in the classes I teach. This is because it is better for students to understand what AI can do and how to use it as a tool in their learning instead of avoiding and fearing it, or being discouraged from using it no matter the circumstances.

Educators should therefore reframe the idea of ChatGPT in their minds, have open discussions with students about its uses, and help them understand that it is actually just another tool to help them learn more efficiently – and not a replacement for their own thoughts and words. Such frank discussions help students develop their critical thinking skills and start understanding their own influence on ChatGPT and other AI-powered tools.

By developing one’s understanding of AI’s actual capabilities, one can begin to understand its uses in everyday life. Some would have people believe that this means countless jobs will inevitably become obsolete, but that is not entirely true. Even if AI does replace some jobs, it will still need industry experts to guide it, meaning that entirely new jobs are being created at the same time as some older jobs are disappearing.

Adapting to AI is a new challenge for most industries, and it is certainly daunting at times. The reality, however, is that AI is not here to steal people’s jobs. If anything, it will change the nature of some jobs and may even improve them by making human workers more efficient and productive. If AI is to be a truly useful tool, it will still need humans. One should remember that humans working alongside AI and using it as a tool is key, because in most cases AI cannot do the job of a person by itself.

Is AI biased?

Why should one view AI as a tool and not a replacement? The main reason is because AI itself is still learning, and AI-powered tools such as ChatGPT do not understand bias. As a result, whenever ChatGPT is asked a question it will pull information from anywhere, and so it can easily repeat old biases. AI is learning from previous data, much of which is biased or out of date. Data about home ownership and mortgages, e.g., are often biased because non-white people in the United States could not get a mortgage until after the 1960s. The effect on data due to this lending discrimination is only now being fully understood.

AI is certainly biased at times, but that stems from human bias. Again, this just reinforces the need for humans to be in control of AI. AI is like a young child in that it is still absorbing what is happening around it. People must therefore not fear it, but instead guide it in the right direction.

For AI to be used as a tool, it must be treated as such. If one wanted to build a house, one would not expect one’s tools to be able to do the job alone – and AI must be viewed through a similar lens. By acknowledging this aspect of AI and taking control of humans’ role in its development, the world would be better placed to reap the benefits and quash the fears associated with AI. One should therefore not assume that all the doom and gloom one reads about AI is exactly as it seems. Instead, people should try experimenting with it and learning from it, and maybe soon they will realize that it was the best thing that could have happened to humanity.

The data emerges from a survey carried out on LinkedIn by OPIT – Open Institute of Technology on the occasion of the start of the new academic year of the institution led by Francesco Profumo

Artificial Intelligence must become a subject of study starting from High School, given that this expertise is increasingly requested in job advertisements. This is the opinion of the LinkedIn community, consulted by OPIT – Open Institute of Technology, an academic institution accredited in the EU, led by Professor Francesco Profumo, former Minister of Education and Rector, and by Riccardo Ocleppo, founder and director. 66% of those who frequent the famous social network believe it is essential to introduce the teaching of Artificial Intelligence already in High School. Additionally, 72% noted an increase in mentions of AI in job ads, while 48% said the use of AI was considered an essential requirement by the companies where they applied for jobs. 38% use Artificial Intelligence mainly for writing texts, a further 38% for specific analysis and research, while 23% use it for translations.

OPIT

Open Institute of Technology carried out the survey on a sample of its followers (to date there are around 8,000 followers worldwide). The survey was launched on the occasion of the start of the new academic year of OPIT (October 2024) and involved professionals, students and technology enthusiasts, offering a significant insight into the perceptions and current trends regarding the use and teaching of Artificial Intelligence. The evidence from the survey highlights an increasingly widespread propensity towards a future in which Artificial Intelligence plays a crucial role. It is no longer a distant concept, but a reality that is already manifesting itself in daily work dynamics. Companies and professionals are rapidly adapting their strategies and skills to remain competitive in an ever-changing market, where the use of AI has become a fundamental element.

“Opportunities to innovate and improve professional development”

“The growing awareness of the importance of Artificial Intelligence in the workplace suggests that professionals are actively integrating these skills into their daily practices. This change offers opportunities to innovate and improve professional development” – explained Riccardo Ocleppo. “The technological transition we are experiencing is rapidly transforming the world of work, and AI will be increasingly central to this evolution. Rather than fear it, it is essential to study it, know it and understand its potential. Only through conscious preparation and a proactive approach will we be able to make the most of the opportunities that this technology offers. One of the distinctive elements of OPIT is precisely the integration of the teaching of Artificial Intelligence, in different modalities and with different perspectives, in all programs. This approach provides students with the appropriate tools to successfully face a constantly changing professional context, characterized by the growing demand for updated skills in the digital field”.

Reference academic reality

With two degrees already started in September 2023 – a three-year degree in Modern Computer Science and a Master’s degree in Applied Data Science & AI – and four new degree courses starting in September 2024 (a three-year degree in Digital Business, and the Master’s degrees in Enterprise Cybersecurity, Digital Business & Innovation and Responsible Artificial Intelligence, which brings the overall offer to 6 degrees), today OPIT is an academic institution of reference for those who intend to take up the challenges of a job market increasingly projected towards Artificial Intelligence, technology, digitalisation and information security. And the interest in three-year degrees in Computer Science and Digital Business is such that OPIT has reopened registrations for these courses, offering the possibility of entry from January. Today OPIT has more than 300 students from 78 countries around the world. The highest percentages come from Italy (31%) and Europe (36%) followed, to a lesser extent, by other areas of the world: North America, Asia, Africa, Latin America and the Middle East.

Artificial Intelligence is now the leading edge of technology, driving unprecedented advancements across sectors. From healthcare to finance, education to environment, the AI industry is witnessing a skyrocketing demand for professionals. However, the path to creating a successful career in AI is multifaceted and constantly evolving. What does it take and what does one need in order to create a highly successful career in AI?

In this interview series, we are talking to successful AI professionals, AI founders, AI CEOs, educators in the field, AI researchers, HR managers in tech companies, and anyone who holds authority in the realm of Artificial Intelligence to inspire and guide those who are eager to embark on this exciting career path.

As part of this series, we had the pleasure of interviewing Zorina Alliata.

Zorina Alliata is an expert in AI, with over 20 years of experience in tech, and over 10 years in AI itself. As an educator, Zorina Alliata is passionate about learning, access to education and about creating the career you want. She implores us to learn more about ethics in AI, and not to fear AI, but to embrace it.

Thank you so much for joining us in this interview series! Before we dive in, our readers would like to learn a bit about your origin story. Can you share with us a bit about your childhood and how you grew up?

I was born in Romania, and grew up during communism, a very dark period in our history. I was a curious child and my parents, both teachers, encouraged me to learn new things all the time. Unfortunately, in communism, there was not a lot to do for a kid who wanted to learn: there was no TV, very few books and only ones that were approved by the state, and generally very few activities outside of school. Being an “intellectual” was a bad thing in the eyes of the government. They preferred people who did not read or think too much. I found great relief in writing, I have been writing stories and poetry since I was about ten years old. I was published with my first poem at 16 years old, in a national literature magazine.

AI, and its integration with society, had an incredible acceleration in recent months. By now, it seems certain that AI will be the fourth GPT (General Purpose Technology) of human history: one of those few technologies or inventions that radically and indelibly change society. The last of these technologies was ICT (internet, semiconductor industry, telecommunications); before this, electricity and the steam engine were the first 2 GPTs.

All three GPTs had a huge impact on the overall productivity and advancement of our society with, of course, a profound impact on the world of work. Such an impact, though, was very different across these technologies. The advent of electricity and the steam motor allowed the displacement of large masses of workers from more archaic and manual jobs to their equivalent jobs in the new industrial era, where not many skills were required. The advent of ICT, on the other hand, has generated enormous job opportunities, but also the need to develop meaningful skills to pursue them.

As a result, an increasingly large share of the economic benefit deriving from the advent of ICT has gradually been polarized towards people who had (and have) these skills in society. Suffice it to say that, already in 2017, the richest 1% of America owned twice the wealth of the “poorest” 90%.

It is difficult to make predictions about how the advent of AI will impact this trend already underway. But there are some very clear elements: one of these is that quality education in technology (and not only) will increasingly play a primary role in being able to secure the best career opportunities for a successful future in this new era.

To play a “lead actor” role in this change, though, the world of education – and in particular that of undergraduate and postgraduate education – requires a huge change towards being much more flexible, aligned to today’s needs of students and companies, and affordable.

This model needs to be seriously challenged and adapted to the times: solid foundational learning remains an essential prerogative. But in a “fast” world in rapid change like today’s, knowledge acquired along this “linear” path will not be able to accompany people in their professions until the end of their careers. The “utility period” of the knowledge we acquire today reduces every day, and this emphasizes how essential continuous learning is throughout our lives.

The transition must therefore be towards a more circular pattern for learning. A model in which one returns “to the school desk” several times in life, in order to update oneself, and forget “obsolete” knowledge, making room for new production models, new ways of thinking, organizing, and new technologies.

In this context, Education providers must rethink the way they operate and how they intend to address this need for lifelong learning.

Higher Education Institutions, as accredited bodies and guarantors of the quality of education (OPIT – Open Institute of Technology among these), have the honor of playing a primary role in this transition.

But also the great burden of rethinking their model from scratch which, in a digital age, cannot be a pure and simple digital transposition of the old analog learning model.

The Institutions Universities are called upon to review and keep updated their own study programmes, think of new, more flexible and faster ways of offering them to a wider public, forge greater connections with companies, and ultimately provide them with students who are immediately ready to successfully enter the dynamics of production. And, of course, be more affordable and accessible: quality education in the AI era cannot cost tens of thousands of dollars, and needs to be accessed from wherever the students are.

With OPIT – Open Institute of Technology, this is the path we have taken, taking advantage of the great privilege of being able to start a new path, without preconceptions or “attachment” to the past. We envision a model of a new, digital-first, higher education institution capable of addressing all the points above, and accompany students and professionals throughout their lifetime learning journey.

We are at the beginning, and we hope that the modern and fresh approach we are following can be an interesting starting point for other universities as well.

Reinforcement learning is a very useful (and currently popular) subtype of machine learning and artificial intelligence. It is based on the principle that agents, when placed in an interactive environment, can learn from their actions via rewards associated with the actions, and improve the time to achieve their goal.

In this article, we’ll explore the fundamental concepts of reinforcement learning and discuss its key components, types, and applications.

Definition of Reinforcement Learning

We can define reinforcement learning as a machine learning technique involving an agent who needs to decide which actions it needs to do to perform a task that has been assigned to it most effectively. For this, rewards are assigned to the different actions that the agent can take at different situations or states of the environment. Initially, the agent has no idea about the best or correct actions. Using reinforcement learning, it explores its action choices via trial and error and figures out the best set of actions for completing its assigned task.

The basic idea behind a reinforcement learning agent is to learn from experience. Just like humans learn lessons from their past successes and mistakes, reinforcement learning agents do the same – when they do something “good” they get a reward, but, if they do something “bad”, they get penalized. The reward reinforces the good actions while the penalty avoids the bad ones.

Reinforcement learning requires several key components:

• Agent – This is the “who” or the subject of the process, which performs different actions to perform a task that has been assigned to it.
• Environment – This is the “where” or a situation in which the agent is placed.
• Actions – This is the “what” or the steps an agent needs to take to reach the goal.
• Rewards – This is the feedback an agent receives after performing an action.

Before we dig deep into the technicalities, let’s warm up with a real-life example. Reinforcement isn’t new, and we’ve used it for different purposes for centuries. One of the most basic examples is dog training.

Let’s say you’re in a park, trying to teach your dog to fetch a ball. In this case, the dog is the agent, and the park is the environment. Once you throw the ball, the dog will run to catch it, and that’s the action part. When he brings the ball back to you and releases it, he’ll get a reward (a treat). Since he got a reward, the dog will understand that his actions were appropriate and will repeat them in the future. If the dog doesn’t bring the ball back, he may get some “punishment” – you may ignore him or say “No!” After a few attempts (or more than a few, depending on how stubborn your dog is), the dog will fetch the ball with ease.

We can say that the reinforcement learning process has three steps:

1. Interaction
2. Learning
3. Decision-making

Types of Reinforcement Learning

There are two types of reinforcement learning: model-based and model-free.

Model-Based Reinforcement Learning

With model-based reinforcement learning (RL), there’s a model that an agent uses to create additional experiences. Think of this model as a mental image that the agent can analyze to assess whether particular strategies could work.

Some of the advantages of this RL type are:

• It doesn’t need a lot of samples.
• It can save time.
• It offers a safe environment for testing and exploration.

The potential drawbacks are:

• Its performance relies on the model. If the model isn’t good, the performance won’t be good either.
• It’s quite complex.

Model-Free Reinforcement Learning

In this case, an agent doesn’t rely on a model. Instead, the basis for its actions lies in direct interactions with the environment. An agent tries different scenarios and tests whether they’re successful. If yes, the agent will keep repeating them. If not, it will try another scenario until it finds the right one.

What are the advantages of model-free reinforcement learning?

• It doesn’t depend on a model’s accuracy.
• It’s not as computationally complex as model-based RL.
• It’s often better for real-life situations.

Some of the drawbacks are:

• It requires more exploration, so it can be more time-consuming.
• It can be dangerous because it relies on real-life interactions.

Model-Based vs. Model-Free Reinforcement Learning: Example

Understanding model-based and model-free RL can be challenging because they often seem too complex and abstract. We’ll try to make the concepts easier to understand through a real-life example.

Let’s say you have two soccer teams that have never played each other before. Therefore, neither of the teams knows what to expect. At the beginning of the match, Team A tries different strategies to see whether they can score a goal. When they find a strategy that works, they’ll keep using it to score more goals. This is model-free reinforcement learning.

On the other hand, Team B came prepared. They spent hours investigating strategies and examining the opponent. The players came up with tactics based on their interpretation of how Team A will play. This is model-based reinforcement learning.

Who will be more successful? There’s no way to tell. Team B may be more successful in the beginning because they have previous knowledge. But Team A can catch up quickly, especially if they use the right tactics from the start.

Reinforcement Learning Algorithms

A reinforcement learning algorithm specifies how an agent learns suitable actions from the rewards. RL algorithms are divided into two categories: value-based and policy gradient-based.

Value-Based Algorithms

Value-based algorithms learn the value at each state of the environment, where the value of a state is given by the expected rewards to complete the task while starting from that state.

Q-Learning

This model-free, off-policy RL algorithm focuses on providing guidelines to the agent on what actions to take and under what circumstances to win the reward. The algorithm uses Q-tables in which it calculates the potential rewards for different state-action pairs in the environment. The table contains Q-values that get updated after each action during the agent’s training. During execution, the agent goes back to this table to see which actions have the best value.

Deep Q-Networks (DQN)

Deep Q-networks, or deep q-learning, operate similarly to q-learning. The main difference is that the algorithm in this case is based on neural networks.

SARSA

The acronym stands for state-action-reward-state-action. SARSA is an on-policy RL algorithm that uses the current action from the current policy to learn the value.

Policy-Based Algorithms

These algorithms directly update the policy to maximize the reward. There are different policy gradient-based algorithms: REINFORCE, proximal policy optimization, trust region policy optimization, actor-critic algorithms, advantage actor-critic, deep deterministic policy gradient (DDPG), and twin-delayed DDPG.

Examples of Reinforcement Learning Applications

The advantages of reinforcement learning have been recognized in many spheres. Here are several concrete applications of RL.

Robotics and Automation

With RL, robotic arms can be trained to perform human-like tasks. Robotic arms can give you a hand in warehouse management, packaging, quality testing, defect inspection, and many other aspects.

Another notable role of RL lies in automation, and self-driving cars are an excellent example. They’re introduced to different situations through which they learn how to behave in specific circumstances and offer better performance.

Gaming and Entertainment

Gaming and entertainment industries certainly benefit from RL in many ways. From AlphaGo (the first program that has beaten a human in the board game Go) to video games AI, RL offers limitless possibilities.

Finance and Trading

RL can optimize and improve trading strategies, help with portfolio management, minimize risks that come with running a business, and maximize profit.

Healthcare and Medicine

RL can help healthcare workers customize the best treatment plan for their patients, focusing on personalization. It can also play a major role in drug discovery and testing, allowing the entire sector to get one step closer to curing patients quickly and efficiently.

Basics for Implementing Reinforcement Learning

The success of reinforcement learning in a specific area depends on many factors.

First, you need to analyze a specific situation and see which RL algorithm suits it. Your job doesn’t end there; now you need to define the environment and the agent and figure out the right reward system. Without them, RL doesn’t exist. Next, allow the agent to put its detective cap on and explore new features, but ensure it uses the existing knowledge adequately (strike the right balance between exploration and exploitation). Since RL changes rapidly, you want to keep your model updated. Examine it every now and then to see what you can tweak to keep your model in top shape.

Explore the World of Possibilities With Reinforcement Learning

Reinforcement learning goes hand-in-hand with the development and modernization of many industries. We’ve been witnesses to the incredible things RL can achieve when used correctly, and the future looks even better. Hop in on the RL train and immerse yourself in this fascinating world.

The artificial intelligence market was estimated to be worth $136 billion in 2022, with projections of up to $1,800 billion by the end of the decade. More than a third of companies today implement AI in their business processes, and over 40% will consider doing so in the future.

These whopping numbers testify to the importance, prevalence, and reality of AI in the modern world. If you’re considering an education in AI, you’re looking at a highly rewarding and prosperous future career. But what are the applications of artificial intelligence, and how did it all begin? Let’s start from scratch.

What Is Artificial Intelligence?

Artificial intelligence definition describes AI as a part of computer science that focuses on building programs and software with human intelligence. There are four types of artificial intelligence: the theory of mind, reactive, self-aware, and limited memory.

Reactive AI masters one field, like playing chess, performing a single manufacturing task, and similar. Limited memory machines can gather and remember information and use findings to offer recommendations (hotels, restaurants, etc.).

Theory of mind is a more developed type of AI capable of understanding human emotions. These machines can also take part in social interactions. Finally, self-aware AI is a conscious machine, but its development is reserved for the future.

History of Artificial Intelligence

The concept of artificial intelligence has roots in the 1950s. This was when AI became an academic discipline, and scientists started publishing papers about it. It all started with Alan Turing and his paper about computer machinery and intelligence that introduced basic AI concepts.

Here are some important milestones in the artificial intelligence field:

• 1952 – Arthur Samuel created a program that taught itself to play checkers.
• 1955 – John McCarthy’s workshop on AI, where the term was used for the first time.
• 1961 – First robot worker on a General Motors factory’s assembly line.
• 1980 – First conference on AI.
• 1986 – Demonstration of the first driverless car.
• 1997 – A program beat Gary Kasparov in a legendary chess match, thus becoming the first AI tool to win in a competition over a human.
• 2000 – Development of a robot that simulates a person’s body movement and human emotions.

AI in the 21st Century

The 21st century has witnessed some of the fastest advancements and applications of artificial intelligence across industries. Robots are becoming more sophisticated, they land on other planets, work in shops, clean, and much more. Global corporations like Facebook, Twitter, Netflix, and others regularly use AI tools in marketing to boost user experience, etc.

We’re also seeing the rise of AI chatbots like ChatGPT that can create content indistinguishable from human content.

Fields Used in Artificial Intelligence

Artificial intelligence relies on the use of numerous technologies:

• Machine Learning – Making apps and processes that can perform tasks like humans.
• Natural Language Processing – Training computers to understand words like humans.
• Computer Vision – Developing tools and programs that can read visual data and take information from it.
• Robotics – Programming agents to perform tasks in the physical world.

Applications of Artificial Intelligence

Below is an overview of applications of artificial intelligence across industries.

Automation

Any business and sector that relies on automation can use AI tools for faster data processing. By implementing advanced artificial intelligence tools into daily processes, you can save time and resources.

Healthcare

Fraud is common in healthcare. AI in this field is mostly oriented toward lowering the risk of fraud and administrative fees. For example, using AI makes it possible to check insurance claims and find inconsistencies.

Similarly, AI can help advance and finetune medical research, telemedicine, medical training, patient engagement, and support. There’s virtually no aspect of healthcare and medicine that couldn’t benefit from AI.

Business

Businesses across industries benefit from AI to finetune various aspects like the hiring process, threat detection, analytics, task automation, and more. Business owners and managers can make better-informed business decisions with less risk of error.

Education

Modern-day education offers personalized programs tailored to the individual learner’s abilities and goals. By automating tasks with AI tools, teachers can spend more time helping students progress faster in their studies.

Security

Security has never been more important following the rise of web applications, online shopping, and data sharing. With so much sensitive information shared daily, AI can help increase data protection and mitigate hacking attacks and threats. Systems with AI features can diagnose, scan, and detect threats.

Benefits and Challenges of Artificial Intelligence

There are enormous benefits of AI applications that can revolutionize any industry. Here are just some of them:

Automation and Increased Efficiency

AI helps streamline repetitive tasks, automate processes, and boost work efficiency. This characteristic of AI is already visible in all industries, and the use of programming languages like R and Python makes it all possible.

Improved Decision Making

Stakeholders can use AI to analyze immense amounts of data (with millions or billions of pieces of information) and make better-informed business decisions. Compare this to limited data analysis of the past, where researchers only had access to local documents or libraries, and you can understand how AI empowers present-day business owners.

Cost Savings

By automating tasks and streamlining processes, businesses also spend less money. Savings in terms of energy, extra work hour costs, materials, and even HR are significant. When you use AI right, you can turn almost any project into reality with minimal cost.

Challenges of AI

Despite the numerous benefits, AI also comes with a few challenges:

Data Privacy and Security

All AI developments take place online. The web still lacks proper laws on data protection and privacy, and it’s highly possible that user data is being used without consent in AI projects worldwide. Until strict laws are enacted, AI will continue to pose a threat to data privacy.

Algorithmic Bias

Algorithms today assist humans in decision-making. Stakeholders and regular users rely on data provided by AI tools to complete or approach tasks and even form new beliefs and behaviors. Poorly trained machines can encourage human biases, which can be especially harmful.

Job Less

AI is developing at the speed of light. Many tools are already replacing human labor in both the physical and digital worlds. A question remains to what degree machines will overtake the labor market in the future.

Artificial Intelligence Examples

Let’s look at real-world examples of artificial intelligence across applications and industries.

Virtual Assistants

Apple was the first company to introduce a virtual assistant based on AI. We know the tool today by the name of Siri. Numerous other companies like Amazon and Google have followed suit, so now we have Alexa, Google Assistant, and many other AI talking assistants.

Recommendation Systems

Users today find it ever more challenging to resist addictive content online. We’re often glued to our phones because our Instagram feed keeps suggesting must-watch Reels. The same goes for Netflix and its binge-worthy shows. These platforms use AI to enhance their recommendation system and offer ads, TV shows, or videos you love.

Shopping on Amazon works in a similar fashion. Even Spotify uses AI to offer audio recommendations to customers. It relies on your previous search history, liked content, and similar data to provide new suggestions.

Autonomous Vehicles

New-age vehicles powered by AI have sophisticated systems that make commuting easier than ever. Tesla’s latest AI software can collect information in real-time from the multiple cameras on the vehicles. The AI makes a 3D map with roads, obstacles, traffic lights, and other elements to make your ride safer.

Waymo has a similar system of lidar sensors around the vehicles that send pulsations around the car and offer an overview of the car’s surroundings.

Fraud Detection

Banks and credit card companies implement AI algorithms to prevent fraud. Advanced software helps these companies understand their customers and prevent non-authorized users from making payments or completing other unauthorized actions.

Image and Voice Recognition

If you have a newer smartphone, you’re already familiar with Face ID and voice assistant tools. These are built on basic AI principles and are being integrated into broader systems like vehicles, vending machines, home appliances, and more.

Deep Learning

Artificial intelligence encompasses both deep learning and machine learning. Machine learning encompasses deep learning and uses algorithms that learn from data, explore patterns, and predict outputs.

Deep learning relies on sophisticated neural networks similar to the networks in the human brain. Deep learning specialists use these neural networks to pinpoint patterns in large data sets.

Artificial Intelligence Continues to Grow and Develop

Although predicting the future is impossible, numerous AI specialists expect to see further development in this computer science discipline. More businesses will start implementing AI and we’ll see more autonomous vehicles and smarter robotics. That said, it’s increasingly important to take into account ethical considerations. As long as we use AI ethically, there’s no danger to our social interactions and privacy.

The future looks bright for the data science sector, with the U.S. Bureau of Labor Statistics stating that there were 113,300 jobs in the industry in 2021. Growth is also a major plus. The same resource estimates a 36% increase in data scientist roles between 2021 and 2031, which outpaces the national average considerably. Combine that with attractive salaries (Indeed says the average salary for a data scientist is $130,556) and you have an industry that’s ready and waiting for new talent.

That’s where you come in, as you’re exploring the possibilities in data science and need to find the appropriate educational tools to help you enter the field. A Master’s degree may be a good choice, leading to the obvious question – do you need a Master’s for data science?

The Value of a Masters in Data Science

There’s plenty of value to committing the time (and money) to earning your data science Master’s degree:

• In-depth knowledge and skills – A Master’s degree is a structured course that puts you in front of some of the leading minds in the field. You’ll develop very specific skills (most applying to the working world) and can access huge wellsprings of knowledge in the forms of your professors and their resources.
• Networking opportunities – Access to professors (and similar professionals) enables you to build connections with people who can give you a leg up when you enter the working world. You’ll also work with other students, with your peers offering as much potential for startup ideas and new roles as your professors.
• Increased job opportunities – With salaries in the $130,000 range, there’s clearly plenty of potential for a comfortable career pursuing a subject that you love. Having a Master’s degree in data science on your resume demonstrates that you’ve reached a certain skill threshold for employers, making them more likely to hire you.

Having said all of that, the answer to “do I need a Master’s for data science?” is “not necessarily.” There are actually some downsides to going down the formal studying route:

• The time commitment – Data science programs vary in length, though you can expect to commit at least 12 months of your life to your studies. Most courses require about two years of full-time study, which is a substantial time commitment given that you’ve already earned a degree and have job opportunities waiting.
• Your financial investment – A Master’s in data science can cost anywhere between about $10,000 for an online course to over $50,000 for courses from more prestigious institutions. For instance, Tufts University’s course requires a total investment of $54,304 if you wish to complete all of your credit hours.
• Opportunity cost – When opportunity beckons, committing two more years to your studies may lead to you missing out. Say a friend has a great idea for a startup, or you’re offered a role at a prestigious company after completing your undergraduate studies. Saying “no” to those opportunities may come back to bite you if they’re not waiting for you when you complete your Master’s degree.

Alternatives to a Masters in Data Science

If spending time and money on earning a Master’s degree isn’t to your liking, there are some alternative ways to develop data science skills.

Self-Learning and Online Resources

With the web offering a world of information at your fingertips, self-learning is a viable option (assuming you get something to show for it). Options include the following:

• Online courses and tutorials – The ability to learn at your own pace, rather than being tied into a multi-year degree, is the key benefit of online courses and tutorials. Some prestigious universities (including MIT and Harvard) even offer more bite-sized ways to get into data science. Reputation (both for the course and its providers) can be a problem, though, as some employers prefer candidates with more formal educations.
• Books and articles – The seemingly old-school method of book learning can take you far when it comes to learning about the ins and outs of data science. While published books help with theory, articles can keep you abreast of the latest developments in the field. Unfortunately, listing a bunch of books and articles that you’ve read on a resume isn’t the same as having a formal qualification.
• Data science competitions – Several organizations (such as Kaggle) offer data science competitions designed to test your skills. In addition to giving you the opportunity to wield your growing skillset, these competitions come with the dual benefits of prestige and prizes.

Bootcamps and Certificate Programs

Like the previously mentioned competitions, bootcamps offer intensive tests of your data science skills, with the added bonus of a job waiting for you at the end (in some cases). Think of them like cramming for an exam – you do a lot in a short time (often a few months) to get a reward at the end.

The prospect of landing a job after completing a bootcamp is great, but the study methods aren’t for everybody. If you thrive in a slower-paced environment, particularly one that allows you to expand your skillset gradually, an intensive bootcamp may be intimidating and counter to your educational needs.

Gaining Experience Through Internships and Entry-Level Positions

Any recent graduate who’s seen a job listing that asks for a degree and several years of experience can tell you how much employers value hands-on experience. That’s as true in data science as it is in any other field, which is where internships come in. An internship is an unpaid position (often with a prestigious company) that’s ideal for learning the workplace ropes and forming connections with people who can help you advance your career.

If an internship sounds right for you, consider these tips that may make them easier to find:

• Check the job posting platforms – The likes of Indeed and LinkedIn are great places to find companies (and the people within them) who may offer internships. There are also intern-dedicated websites, such as internships.com, which focus specifically on this type of employment.
• Meet the basic requirements – Most internships don’t require you to have formal qualifications, such as a Master’s degree, to apply. But by the same token, companies won’t accept you for a data science internship if you have no experience with computers. A solid understanding of major programming and scripting languages, such as Java, SQL, and C++, gives you a major head start. You’ve also got a better chance of landing a role if you enrolled in an undergraduate program (or have completed one) in computer science, math, or a similar field.
• Check individual business websites – Not all companies run to LinkedIn or job posting sites when they advertise vacant positions. Some put those roles on their own websites, meaning a little more in-depth searching can pay off. Create a list of companies that you believe you’d enjoy working for and check their business websites to see if they’re offering internships via their sites.

Factors to Consider When Deciding if a Masters Is Necessary

You know that the answer to “Do you need a Master’s for data science?” is “no,” but there are downsides to the alternatives. Being able to prove your skills on a resume is a must, which the self-learning route doesn’t always provide, and some alternatives may be too fast-paced for those who want to take their time getting to grips with the subject. When making your choice, the following four factors should play into your decision-making

Personal Goals and Career Aspirations

The opportunity cost factor often comes into play here, as you may find that some entry-level roles for computer science graduates can “teach you as you go” when it comes to data science. Still, you may not want to feel like you’re stuck in a lower role for several years when you could advance faster with a Master’s under your belt. So, consider charting your ideal career course, with the positions that best align with your goals, to figure out if you’ll need a Master’s to get you to where you want to go.

Current Level of Education and Experience

Some of the options for getting into data science aren’t available to those with limited experience. For example, anybody can make their start with books and articles, which have no barrier to entry. But many internships require demonstrable proof that you understand various programming and scripting languages, with some also asking to see evidence of formal education. As for a Master’s degree, you’ll need a BSc in computer science (or an equivalent degree) to walk down that path.

Financial Considerations

Money makes the educational wheel turn, at least when it comes to formal education. As mentioned, a Master’s in data science can set you back up to $50,000, which may sting (and even be unfeasible) if you already have student loans to pay off for an undergraduate degree. Online courses are more cost-effective (and offer certification), while bootcamps and competitions can either pay you for learning or set you up in a career if you succeed.

Time Commitment and Flexibility

The simple question here is how long do you want to wait to start your career in data science? The patient person can afford to spend a couple of years earning their Master’s degree, and will benefit from having formal and respectable proof of their skills when they’re done. But if you want to get started right now, internships combined with more flexible online courses may provide a faster route to your goal.

A Master’s Degree – Do You Need It to Master Data Science?

Everybody’s answer is different when they ask themselves “do I need a Master’s in data science?” Some prefer the formalized approach that a Master’s offers, along with the exposure to industry professionals that may set them up for strong careers in the future. Others are less patient, preferring to quickly develop skills in a bootcamp, while yet others want a more free-form educational experience that is malleable to their needs and time constraints.

In the end, your circumstances, career goals, and educational preferences are the main factors when deciding which route to take. A Master’s degree is never a bad thing to have on your resume, but it’s not essential for a career in data science. Explore your options and choose whatever works best for you.
