What are the Four Main Types of AI?

Due to its impact on creating new opportunities that are beyond human capability across almost every sector, it may not come as a surprise that there are different types of artificial intelligence (AI).  

If you’re a technology or AI enthusiast and want to find out more, keep reading as this blog gives you the insight you need about the four different forms of AI! We also explain how you can develop your understanding further with a BSc (Hons) Artificial Intelligence degree. 

Reactive Machines  

Starting with the most basic forms of unsupervised AI, we have reactive machines. These have no memory and are task-specific, meaning that input always delivers the same output as they can’t use past experiences to influence present decisions. Examples of reactive machines would be machine learning models. This is because they are used to take customer data and use it to make recommendations to the same customers. 

Despite being one of the most basic forms of AI, it is classed as ‘super’ as humans would be unable to take data in this way and make relevant recommendations. Take the ‘recommended for you’ section on Netflix, for instance. A human wouldn’t be able to store the data based on Netflix shows someone has watched and make recommendations on similar shows that they might also like. This is an example of how reactive machines come into their own.  

Limited Memory 

At number two, there’s limited memory. This refers to AI’s ability to restore previous data, with the intention of using the data to make better future predictions. If you’re wondering how this works, the answer lies with the algorithm and how it imitates the way our brain neurons’ work together. This also means that over time, the algorithm will get smarter as it receives more data to train on. 

As an example of limited memory in action, we have Tesla’s driverless cars and the way they observe the speed, direction and proximity of other cars to determine how to function.  

Theory of Mind 

Considering the aim of AI is to replicate the level of human-like intelligence and more, this makes the theory of mind function a fitting one to talk about. It refers to the ability of the human mind to attribute human mind to others. The key difference of this to the other types of AI is that it will be built in the future. If developed, the opportunities are endless. It could allow for the understanding of how and why people have different thoughts and emotions, with the intention of predicting behaviour and simulating human relationships.  

Self-Awareness 

Going a step beyond the theory of mind is the idea of self-awareness; a form of AI that is still a long way off as there is a lot yet to uncover about brain intelligence. The main aim of it is to not only understand emotions, but to get to grips with people’s state of mind and use this data to predict other people’s feelings.
