How many types of AI are there on the basis of functionality?

Artificial intelligence is divided into 4types which are as follows:

• Reactive Machines:
• Absolutely responsive machines are the most essential kinds of Artificial Intelligence.
• Such AI frameworks don’t store r memories or past experiences encounters for future activities.
• These machines just focus on current situations and respond on it according to best activity.
• IBM’s Deep Blue framework is an illustration of reactive machines.
• Google’s AlphaGo is additionally an illustration of reactive machines.

• Limited Memory:

• Can store past experiences and data for a short period of time.
• Self-driving cars are one of the best examples of Limited Memory systems. These cars can store recent speed of nearby cars, the distance of other cars, speed limit, and other information to navigate the road.

• Theory of Mind:

• Thoery of Mind AI is capable of understanding human behaviour, actions, emotions and belief and be able to interact like humans
• The researchers are very close to developing such machines but have not been fully successful

• Self Awareness:

• It is the future of AI as these machines would be able to have their own Consciousness, self aware.
• This is a hypothetical concept as it assumes that machines are smarter than humans.
