Artificial intelligence, both as a word and as a field of study and application, has gained a tremendous amount of momentum over the past few years. With the ever-growing relevance of data in the decision-making process of most institutions and companies, the rise of different types of AI, or intelligent systems capable of handling a large amount of data swiftly and efficiently is perhaps a necessity.

However, there is a vast difference between systems capable of handling data fed to them and the sentient, all-powerful beings that pop culture leads us to believe are the end goal of AI. The latter still remains a distant dream, with developers and scientists working extremely hard to make machines more and more like us humans.

In this article, we are going look at the different types of AI, and what the future holds for each category

 

  1. Reactive Machines

These are perhaps the most fundamental of AI systems- they are purely reactive and do not use past experiences to improve future decisions. Neither do they possess the ability to form memories.

Such machines observe the world and make decisions based purely on what they see. A famous example is Deep Blue, IBM’s chess-playing computer that beat Garry Kasparov, an international grandmaster in the 1990s.

 

  1. Limited Memory AI

These types of machines possess the ability to use the past. Limited memory AI is most frequently used today in self-driving cars. Such AI constantly monitor the movement of foreign vehicles around them. This data, along with other static data like traffic lights, lane marks, etc. help self-driving cars avoid accidents.

 

  1. Theory of Mind AI

Theory of Mind is perhaps one for the future. The machines in this category have their own representation of the world. And along with that, they have representations of the entities in the world as well.
The name comes from a term in psychology- the “theory of mind”. It governs that people and other creatures in this world have emotions and thoughts that affect their behavior.

If AI wishes to fulfill the age-old vision of having machines walk amongst humans, being able to understand how each human being thinks and works is crucial.

 

  1. Self Aware AI

This is the final step, and if pop culture is to be believed, the most daunting and frightening one from a moral perspective. Self aware AI machines can form a representation of themselves.
