What are machine learning?
The definitions of machine learning is offered. Arthur Samuel described it as: "The field of study that gives computers the ability to learn without being explicitly prog Rammed. " This was an older, informal definition.
Tom Mitchell provides a more modern definition: 'a computer program was said to learn from experience E with R Espect to some class of tasks T and performance measure P, if it performance at tasks in T, as measured By P, improves with experience E."
Example:playing Checkers.
E = The experience of playing many games of checkers
T = The task of playing checkers.
P = The probability that the program would win the next game.
In general, learning problem can is assigned to one of the broad classifications:
Supervised learning and unsupervised learning.
