Unsupervised learning allows the computer to create rules by trying to partition and classify by itself - without labeled examples or reinforcement signals - data in homogeneous categories.

Supervised learning is one of the three types of learning implemented by artificial neural networks, the other two being unsupervised learning and reinforcement learning.

Machine learning is a process by which a computer or software improves, without human intervention, its mode of operation by acquiring new knowledge and skills from the results it has obtained during previous actions.

Artificial intelligence (AI) refers to the set of theories and technologies used to develop machines or software capable of simulating cognitive functions associated with human intelligence, such as learning or reasoning.
