Machine learning is an old concept that was defined in 1959 by Arthur Samuel as a field of study that gives computers the ability to learn without being explicitly programmed. Tom. M. Mitchel provided a more formal definition. In this definition, Tom links the concept of samples or experiences, labels, and performance measurements.
Note
The machine learning definition by Arthur Samuel is referenced from Some Studies in Machine Learning Using the Game of Checkers in the IBM Journal of Research and Development (Volume: 3, Issue: 3), p. 210 and a phrase in The New Yorker and Office Management the same year.
The more formal definition by Tom. M. Mitchel is referenced from Machine Learning Book, McGray Hill 1997 (http://www.cs.cmu.edu/afs/cs.cmu.edu/user/mitchell/ftp/mlbook.html).
Machine learning involves pattern recognition and the learning theory in artificial intelligence and is related to computational statistics.
Machine learning is used in hundreds of applications...
