What is Artificial Intelligence? IA Meaning and Categories

show table of contents

What is Artificial Intelligence (AI)? It is undoubtedly one of the most incredible technologies of our era, capable of fundamentally transforming the way we live, work, and interact with the world around us.🌍

What is certain is that there will be a world before and a world after, just as there was a world before the internet and a new way of living after its invention. 🤯

We take the time to define AI in this video!

Researchers have worked hard to create algorithms and machine learning systems that can process large amounts of data, understand natural language, and make complex decisions autonomously. It’s pretty crazy, and I’ll explain why…

In this article, you will discover all types of AI and how they work.


What is Artificial Intelligence (A.I.)?

🤖 Artificial intelligence (AI) is a field of computer science that aims to create computer systems that can replicate human functions, such as:

  • Perception,
  • Reasoning,
  • Learning,
  • Understanding,
  • Interaction.

🧐 The benefits of AI are many and varied.


It can be used to improve people’s quality of life by enabling better decision-making in areas such as:

  • Medicine,
  • Agriculture,
  • Environment
  • Safety and security.

🚀 It can also help businesses be more efficient by automating sales processes and providing accurate and timely analysis.


In addition, it can help solve complex problems like:

  • Face recognition,
  • Content creation,
  • Task automation,
  • Fraud detection.

🤔 However, we all know A.I. also raises concerns about its impact on society. Like any major novelty, it worries.

One of the main concerns is the loss of jobs, as some tasks once done by human workers can now be automated.

In addition, there are concerns about the use of AI in situations of surveillance, control, and manipulation. Therefore, it is important to ensure that the tool is used responsibly and ethically.

We talk about the different types of AI in the next chapter! 😉


What is Artificial Intelligence? AI Meaning and types

You probably have a hard time identifying what is artificial intelligence and in which category they fit and well there are about 8 main categories of AI. Some can be hybrid and therefore fall into two categories. 🤯


Weak AI (Chat AI)

This category is also known as the “expert system”. 🤖

It is capable of solving specific problems in a specific domain but lacks the ability to generalize beyond that domain.

For example, “chatbot” belongs to the category of AI called “Natural Language Processing” (NLP), which focuses on the interaction between computers and human language.


Chatbots use NLP algorithms to understand user requests and generate appropriate responses. It can only go so far, i.e. if it doesn’t understand the question, the chatbot offers the alternative “talk to a human”.

💡 Here are some of its features:

  • Analysis of the user’s question to determine the topic of the conversation.
  • Identification of the user’s keywords and intentions.
  • Automatic response to the user based on their question.
  • Ability to direct the user to additional resources if needed.

Chatbots are considered weak because they are limited and answer specific questions in a given context, and cannot understand the conversation as a whole or adapt to more complex situations.


Symbolic AI

This type of AI is based on the manipulation of abstract symbols and is often used in logical reasoning tasks. 🤖🔬

An example of symbolic AI is DXplain, an expert system developed by Harvard Medical School to help doctors diagnose complex diseases. In the same genre, there is Isabel Healthcare, a web-based medical diagnostic expert system that uses logic rules and a knowledge database to help diagnose rare and complex diseases.

They both use symbolic knowledge to solve medical diagnostic problems.

The system uses logical rules to diagnose bacterial infections based on symptoms and medical test results, using medical knowledge represented as logical rules.

💡 Some examples of tasks they can perform are:

  • 🥼 Analyzing patient symptoms and medical history.
  • 💉 Use of logic rules to identify possible causes of symptoms.
  • 🩻 Evaluation of medical test results to refine the diagnosis.


Photo AI (Perception AI)

Perception-based AI categories are capable of perceiving information from sensory data (images or sounds). 🤖👀

An example of a task for this category is image recognition for facial recognition or object detection 🖼️ in videos.

Facial recognition-based AI uses algorithms to identify 👀, analyze, and compare human facial features in images or videos.

The operation of facial recognition AI is based on several key steps:

  • 👩 Face detection.
  • 👩‍🦲 Extraction features.
  • 👱‍♀️👩 Feature comparison.

The name of the first facial recognition AI was “Eigenface.” It was developed in 1991 by researchers at MIT (Massachusetts Institute of Technology) to automatically recognize human faces from digital images.

Now there are new super powerful easy recognition AIs:


Simulation AI

This AI uses simulations to solve complex problems. 🤖🎮

It is often used for planning and decision-making in virtual environments.

A common simulation AI is the flight simulator ✈️, which is used to train pilots for various flight scenarios in a variety of conditions, ranging from emergency situations to severe weather 🍃. There are also simulation AIs for training drivers, doctors, and other professionals.

A few brands offer flight simulators of this type; X-Plane, Microsoft Flight Simulator, Prepar3D, and FlightGear. 🛫

The images, by the way, are breathtaking.

Knowledge-based AI

These AIs use expert knowledge to solve specific problems. 💬

They might look like weak AI, but in reality, there is a nuance.

Let’s use the Chatbot example again 🤖; A chatbot is typically designed to handle simple, repetitive human interactions using pre-made rules and scripts, rather than drawing on a larger, complex knowledge base.

Knowledge AIs, therefore, have access to a much more elaborate database.🌏

Here’s a more concrete example > Cyc is an AI system based on a knowledge base containing information about the world and logical rules for reasoning about that information.


AI in machine learning

While knowledge-based AI uses pre-existing knowledge to solve specific problems, machine learning AI uses algorithms to learn from data and improve its performance over time, and thus, continues to evolve on its own. 🧠

ChatGPT is considered one of the best examples of machine learning AI because of its design based on the transform language model, which has led to a significant improvement in the quality of text generation.

💡 Basically, the tool can answer any question, has uncommon knowledge, and continues to develop its techniques every time a user asks it questions.


AI based on web data

It is used for web search and analysis of large amounts of data. 🤖🕸️

It is often used in applications such as online product research or monitoring public opinion on social media.

For example, Google Search, which uses machine learning to understand user queries and provide relevant search results. 👍

If you’re looking for another example, there’s Facebook News Feed, a filtering algorithm that uses AI to determine which posts should be displayed in each user’s news feed, based on their interests and activity on the site.


AI that enables task optimization

This type of AI is used to find the best possible solutions to a given problem using optimization algorithms. 🤖🚀

It is often used in applications such as delivery route planning or transportation network optimization, and in some cases on prospecting tools or management CRM.

Of course, all the AIs mentioned above are there to optimize tasks, save time and make your life easier.

For example, the recommendation systems used by streaming platforms like Netflix and Spotify to suggest relevant content based on the user’s preferences, are also optimization AI. 😜

Artificial Intelligence are also hybrids

Some AIs are in several categories at once!

For example, ChatGPT is indeed an AI based on machine learning, which specifically uses transform neural networks to generate text.

Also, Google Assistant is a hybrid because it combines machine learning, knowledge AI and conversational AI (natural language processing) to provide a personal assistant experience to the user.
