We all know by now that AI learns, thinks and behaves like humans. AI is a branch of computer
science that focuses on developing machines which can think and work like human beings. In simple
terms, we can define AI as a system which can learn and perform tasks that require a higher level
of intelligence like learning from its past experience, planning and problem solving etc. which any
human being does with ease.
AI has already become an integral part of our daily life, therefore it’s important to understand
what AI can actually do. In fact, AI is a broad term which includes Machine Learning, Big data or
Natural Language Processing (NLP) as its subsets. These subsets can also be classified by the level
of intelligence.
AI can be classified into three categories which are based on the functionality of AI applications.
The given figure shows the classification of AI machines.
