What is Machine Learning ?
Old Machine Learning Definition: Field of study that gives computers the ability to learn without being explicitly programmed.
By Arthur Samuel (1959)
The above statement by Arthur Samuel is considered an Old one. A new one was stated by Tom Mitchell, a friend of Carnegie Melon.
New Machine Learning Definition: A computer program 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, improves with experience E.
By Tom Mitchell (1998)
Experience E: I think this is the data collected overtime.
Task T: Action from the experience
Performance P: Probability of right action
A Question asked by Andre Ng in his class.
Types of Learning:
1) Supervised Learning: We teach the computer how to do something
2) Unsupervised Learning: The computer learns by itself.
