AI is a more advanced field of Learning. Using which one can improve the machine intelligence. The deep architecture of ANN improve the experiences of learning.

All though it's a study inspired by the human brain (neural) architecture, Example: Very very intelligent are humans because of emotions, thinking (@ time learning/update), from childhood to adult we keep learning and improving our experiences, classify everything that has we learned from the surrounding.
