Introduction

Artificial intelligence (AI) is one of the most fascinating and impactful fields of science and technology in the 21st century. AI seems to have the potential to transform various aspects of our lives, from how we communicate, work, learn, shop, travel, and how we perceive the world around us. But what exactly is artificial intelligence, and how does it work?

In this blog post, we will explore the definition, a bit of history, key figures, facts, numbers, industries, and applications of Artificial Intelligence.

What is Artificial Intelligence?

Artificial Intelligence is a Branch of Computer Science that always aims to create machines or software that can perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and natural language processing. Artificial Intelligence can also refer to the intelligence exhibited such man-made machines or software.

But the field of Artificial Intelligence is vast and diverse, and naturally, its definition has evolved and been debated throughout its history. Please consider the following points for a better understanding.

Multiple Perspectives

  • Technical vs. Philosophical: Artificial Intelligence definitions vary depending on their intended audience and purpose. Technical definitions often focus on capabilities like learning, reasoning, and problem-solving, while philosophical definitions might dive quite deep into the questions of consciousness and sentience that may arise in human consciousness.
  • Specific Area vs. Overall Field: Within AI, various subfields like machine learningrobotics, and natural language processing each have their nuances and interpretations of intelligence.

Beyond Individuals

While individuals like McCarthy, Minsky, and Shannon made significant contributions, defining AI is often a collaborative effort. Organizations like the Association for the Advancement of Artificial Intelligence (AAAI) and research groups regularly contribute to refining and discussing AI definitions.

Continuous Evolution

As AI research progresses, so does its definition. New capabilities and challenges constantly emerge, necessitating adaptations and re-evaluations of what constitutes “intelligence” in a machine.

There isn’t just one single definition of Artificial Intelligence and it’s not limited to the work of a few individuals. It’s a dynamic field with diverse perspectives and constantly evolving understandings. Exploring these different viewpoints can provide a richer and more nuanced understanding of what artificial intelligence truly is.

Classification: Narrow AI and General AI.

The Artificial Intelligence that humans refer to is usually classified into 2 main categories.

Narrow AI

Narrow AI is the type of AI that can perform specific tasks or solve specific problems within a limited domain. For example, a chess-playing program or face recognition systems are part of the Narrow AI Domain. Why not remind you of Virtual Assistants like Apple’s Siri, Amazon’s Alexa, which recently got a new voice, and Google Assistant? These are examples of Narrow AI Models too. They are designed to perform tasks like setting alarms, answering questions, and providing weather updates within a limited domain.

But wait! What about the Recommendation Systems? Many online platforms use Narrow AI to make product or content recommendations based on your past behavior. For instance, Netflix suggests movies and TV shows you might like, and Amazon recommends products based on your browsing and purchase history. Expands in other fields like Chatbots, Medical Diagnosis, Autonomous Vehicles, and many others are worth mentioning. Let’s focus back on narrow AI, you can think of it as “narrowing down on something”, focusing on a singular task. For example, a model can be trained to beat humans at chess, it took only a couple of years as you can see in this timeline:

General AI

General AI is the type of Artificial Intelligence that can perform any intellectual task that a human can do across various domains. For example, a general AI could understand natural language, play any game, learn from any data, and reason about any situation. General AI is still a hypothetical concept and has not been achieved yet.

Language Understanding and Translation: A General AI or AGI could understand and translate natural language in real-time, accurately converting text or speech from one language to another, and even grasp nuances and cultural context.

Playing Any Game: An AGI could play and excel at a wide range of games, not just board games or video games but also complex strategy games, sports simulations, and even creative games like improvisational storytelling.

Universal Learning: Unlike narrow AI, a General AI would have the ability to learn from any type of data or domain. It could autonomously acquire knowledge and skills from new information and adapt to various tasks and environments making use of training grounds like NVIDIA Isaac Gym.

But what about Reasoning Across Diverse Situations? AGI would be capable of reasoning, problem-solving, and decision-making in diverse and unstructured situations. It could handle novel problems and adapt its reasoning based on context.

This relates directly to Creative and Innovative Tasks: General AI could engage in creative activities such as generating art, music, literature, and inventions. It could think abstractly, devise new concepts, and come up with solutions to complex problems independently. We are not there yet but in 5 to 10 years, who knows what the future will bring.

While we have made significant progress in Artificial Intelligence, we are currently working with narrow or specialized AI systems that excel in specific tasks, rather than a single AI that can perform any intellectual task across various domains like a human. We need some time to pass .

How does AI work?

AI works using various techniques and methods to process data and learn from it. Some of the most common techniques and methods are:

Machine Learning Algorithm

Machine Learning: is a subset of AI that enables machines or software to learn from data without being explicitly programmed. Machine learning algorithms can find patterns, make predictions, and improve their performance based on feedback or new data. Machine learning can be further divided into supervised learning, unsupervised learning, and reinforcement learning.

Deep Learning Algorithm

Deep learning: is a subset of machine learning that uses artificial neural networks to learn from data. Artificial neural networks are composed of layers of interconnected nodes that mimic the structure and function of biological neurons in the brain. Deep learning can handle complex and high-dimensional data such as images, speech, text, and video.

Natural Language Processing Algorithm

Natural Language Processing: (NLP) is a subset of Artificial Intelligence that deals with the analysis and generation of natural language. NLP can enable machines or software to understand, interpret, and respond to human language in spoken or written form. NLP can be used for various applications such as chatbots, sentiment analysis, machine translation, text summarization, and more.

Computer Vision Algorithm

Computer Vision: is a subset of AI that deals with the processing and understanding of visual information. Computer vision can enable machines or software to recognize, identify, classify, and analyze objects, faces, scenes, and activities in images or videos. Computer vision can be used for various applications such as face recognition, object detection, self-driving cars, medical imaging, and more

The History of Artificial Intelligence


The history of Artificial Intelligence can be traced back to Ancient Times when myths and legends depicted artificial beings endowed with intelligence or consciousness master craftsmen. However, the scientific and philosophical foundations of artificial intelligence began in the 17th and 18th centuries when thinkers such as René Descartes, Gottfried Leibniz, Thomas Hobbes, and David Hume attempted to describe the process of human thinking as the mechanical manipulation of symbols.



  • The field of artificial intelligence research was divided into two main camps: symbolic AI and connectionist AI. Symbolic AI focuses on using logic and symbols to represent knowledge and reasoning. Connectionist AI focuses on using artificial neural networks to learn from data and mimic biological neurons.

  • The field of Artificial Intelligence experienced several cycles of hype and disappointment over the decades. The first cycle was in the 1950s and 1960s when researchers made some remarkable achievements such as creating programs that could play chess (Samuel), prove mathematical theorems (Newell and Simon), understand natural language (Shakey), and solve problems (GPS). However, the limitations and difficulties of scaling up these programs became apparent the 1970s when funding and interest in artificial intelligence declined.

  • The second cycle was in the 1980s when researchers revived interest in artificial intelligence developing expert systems that could encode human knowledge in specific domains such as medicine (MYCIN), engineering (DENDRAL), finance (XCON), and law (PROSPECTOR). However, the brittleness and maintenance issues of these systems became evident the late 1980s when funding and interest in artificial intelligence declined again.
