Introduction
Artificial Intelligence (AI) is the science of creating smart machines—systems that can perform technical tasks such as learning, reasoning, problem-solving, understanding natural language, and perception that typically require human intelligence. It is important to note that machines themselves do not "think" in the human sense.
The AI approach is based on discovery, unlike traditional software projects. The reality of the AI world is statistical and probabilistic, not absolute.
Machine learning models are not programmed with traditional logic.
By leveraging massive datasets, AI algorithms train, learn, and adapt—often outperforming humans in a wide range of tasks.
How Does Artificial Intelligence Work?
Machine Learning (ML):
Machine learning describes the ability of AI systems to learn and make decisions by recognizing patterns and analyzing data from previous experiences. Unlike traditional programming, where every task is explicitly coded, machine learning allows computer systems to learn and improve autonomously.
Just like humans, artificial intelligence requires various learning techniques when first exposed to data. Examples include supervised learning and unsupervised learning (more on these below).
Machine learning is the driving force behind many AI applications, from financial forecasting to recommendations on platforms like Spotify and YouTube. Its capacity to process huge amounts of data, learn patterns, and draw insights is a cornerstone in advancing AI capabilities.
Neural Networks:
These are complex webs of connections that mimic the human brain’s neural network.
Artificial neural networks use a similar approach—rather than asking direct questions to establish context, the neural network leverages thousands or millions of tokens (data points) interconnected based on the training data (e.g., via supervised learning) to predict the next required action.
🔎 Each token or group of tokens can represent a letter/word, for example.
Imagine you want a system to identify a dog in an image:
Humans recognize and understand a dog because we were taught, from a young age, what a dog looks like and how to differentiate it from other animals.
Artificial neural networks work similarly.
First, you feed the system images labeled “dog.”
AI doesn’t look at the label until it reaches its own conclusion.
To provide an answer, the neural network scans every pixel in the image, then “guesses” the output.
Suppose its first guess is a 10% chance that the image is a dog. It compares this guess to the actual label, refines its logic, and adjusts.
Just like humans, the more the neural network trains, the more accurate and contextual its predictions become.
This is called training the neural network—this process builds up the web of connections.
Deep Learning (DL):
A subfield of machine learning, deep learning uses neural networks with many layers (“deep” networks) to analyze data patterns. This enables advanced AI applications like speech recognition and complex image analysis at a high level of accuracy.
Natural Language Processing (NLP):
A branch of machine learning, NLP enables machines to understand and communicate with humans using natural, everyday language. This allows for chatbots, language translation, voice recognition, and summarizing vast amounts of text.
ChatGPT and similar tools are examples of NLP in action through text-based conversations.
Robotics:
Robotics merges AI with mechanical engineering, enabling us to build smart machines that can perform tasks in the physical world—think car manufacturing lines, smart warehouses, drones, and even surgical robots in hospitals.
Cognitive Computing:
This aspect of AI focuses on simulating human thought processes in complex situations where answers may be ambiguous or unclear, aiming for human-like interactions with machines.
Cognitive computing uses all the above (ML, DL, NLP, robotics) plus self-learning algorithms to analyze sentiment, assess risks, and even recognize faces in very low resolution.
It is especially useful in fields like healthcare, banking, finance, and the military.
Learning Methods in Artificial Intelligence
When it comes to machine learning, the key is learning itself.
Imagine learning to play chess. There are several ways to approach it:
One strategy: Hire a teacher who explains the theory, the practical rules, supervises your moves, and corrects your mistakes.
Supervised Learning – An expert teaches a robot by demonstrating moves on a chessboard, illustrating AI learning from labeled guidance. Another strategy: Observe chess players in the park—just by watching, without interaction. You might not know every piece or rule, but after enough observation, you’ll start to grasp the moves.
Unsupervised Learning – An AI quietly observes chess players in the park, discovering patterns without guidance or labels
These strategies closely mirror how machines learn:
Supervised Learning:
The most common method—models learn from labeled data, guided by a human expert (data scientist), making predictions based on input-output pairs.
Unsupervised Learning:
Here, algorithms learn from unlabeled data, analyzing and discovering patterns and relationships within the dataset to improve and refine their analysis and performance.
Examples: Siri, Alexa, Netflix recommendations, and more.
Reinforcement Learning:
Two key characteristics are trial-and-error search and delayed reward.
Reinforcement learning is defined by the absence of pre-existing data. It is Agent-oriented learning, performed through interaction with the environment.
Examples include autonomous cars and investment portfolio management. Reinforcement learning differs from other ML paradigms in that there is no supervisor, only a reward signal, and the feedback is delayed rather than immediate. Time plays an important role (sequentiality), and it is considered more realistic and demanding (like a newborn baby). It includes concepts of Exploration/Exploitation
Other learning methods exist, but I’ll leave those for another time.
Types of Artificial Intelligence
AI can be categorized into three main types:
Narrow AI (ANI – Artificial Narrow Intelligence)
General AI (AGI – Artificial General Intelligence)
Superintelligent AI (ASI – Artificial Super Intelligence)
Let’s break it down:
Narrow AI (ANI):
This is the most common form of AI today.
These systems are designed to solve a single problem and can perform one specific task exceptionally well.
By definition, they have limited capabilities, like recommending products on an e-commerce site or predicting the weather.
This is the only kind of AI that currently exists. It can approach or even exceed human performance in highly specific domains, but only within controlled environments with a defined set of parameters.
General AI (AGI):
Still theoretical (currently). This is AI with human-level cognitive abilities, able to operate across a broad range of domains (language, vision, logical reasoning, etc.).
As of this writing, we’re still far from this technology. To achieve it, we’ll likely need hundreds or thousands of narrow AI systems (ANI) communicating to mimic human thinking.
Only recently did OpenAI announce early-stage research aimed at developing this technology, a testament to the vast complexity of the human brain’s network.
Superintelligent AI (ASI):
A potential future state, where AI surpasses human intelligence in all respects, possibly leading to runaway technological growth beyond human control—a scenario often depicted in science fiction.
This would include rational decision-making, the ability to create art, and even forming emotional relationships.
Once AGI (stage 2) is achieved, the leap to ASI (stage 3) could happen quickly, potentially in ways we can’t yet imagine.

Last words
Artificial intelligence (AI) is a cornerstone of humanity’s technological evolution, breaking ground in countless fields and offering innovative solutions to complex challenges. AI is reshaping our reality, closing the gap between human and machine intelligence. While it presents huge opportunities, it’s important to remember:
AI won’t replace people—those who know how to use it will.
We must also keep in mind (and I’m putting this in asterisk) the ethical and societal challenges that come with integrating AI into our lives. It’s essential to maintain an ongoing dialogue about how we develop and use these technologies to serve human needs while upholding ethical values and norms.
