In the coming age of AI and technology, we see advancements in every corner of our lives. The same is the case with businesses. Organizations all over the are opting for different technological elements to add to their business operations. According to statistics, around 37% of organisations and companies have already added AI to their structure.

But before you pick an AI software for your business, it is crucial to understand the four types.

The Four Most Basic Types

  1. Theory of Mind
  2. Reactive Machines
  3. Limited Memory
  4. Self-Aware.

Here is all you need to know about them.

Theory of Mind

The Theory of Mind type is scarce since it is just starting to get adopted by businesses. However, it can be seen in technologies such as self-driving cars. The idea behind the theory of mind AI is that the technology will coordinate with the emotions and thoughts of human beings.

Reactive Machine

This type is responsible for catering to basic operations with input and output. When we talk about the stages, this is the first one. Any static models of machine learning that you see are working on the model of reactive machines.

Limited Memory

Limited memory type if AI refers to the systems when it can tackle the previous data entered by the user. The AI can tackle previous data, store it, and work on further predictions. This type of AI is highly used in domains where people need prediction-based analyses. Limited Memory can also be divided into three types.

Reinforcement Learning

This type is where the computer or the software learns by the trial-and-error method. When discussing real-life scenarios, this can be most commonly seen when computers are taught how to play different games like DOTA2, Chess, etc.


E-GAN, short for Evolutionary Generative Adverbial Networks, is another type of limited memory. This one comes with a memory that learns to evolve and grow as time grows. While it is self-evolving, there is room for modifications to ensure that the path is as smooth as the user wants.


LSTMs, short for Long, Short-Term Memory, use the previous data to predict what is about to come next.


The last type is the self-aware model. This model is not achieved yet, but it is said that it can be attained shortly. When done, it can change the human race for the better. This system works on the policy of self-awareness. It also comes with independent intelligence. This is said to be the last tier in progress.

According to statistics, nine out of ten leading businesses worldwide make use in one way or another. If you happen to be looking to employ it for your businesses, make sure you know the difference between the four common types.
