What Is Machine Learning?

Arthur Samuel, an American pioneer in the fields of computer gaming and artificial intelligence, invented the phrase Machine Learning in 1959, stating that "it offers computers the ability to learn without being explicitly programmed."

"A computer programme is said to learn from experience E with respect to some task T and some performance measure P, if its performance on T, as measured by P, increases with experience E," Tom Mitchell wrote in 1997.


Machine learning is a subset of AI, which became very popular in 90’s. Artificial Intelligence(AI) deals with building computing machines which imitate human behavior and intelligence to solve complex problems. The goal here is to increase the success in finishing the tasks. Rather than describing the field in cognitive terms, the tasks in which machine learning(ML) is concerned offer an essentially operational description. ML aims to increase the accuracy of it's learning algorithm rather than bothering about the success.
