What Is Machine Learning?

Machine Learning is the science (and art) of programming computers so they can learn from data.

Here is a slightly more general definition: -

[Machine Learning is the field of study that gives computers the ability to learn without being explicitly programmed.]

-Arthur Samuel, 1959

Machine learning is also a subfield of artificial intelligence. Its goal is to enable computers to learn on their own. A machine’s learning algorithm enables it to identify patterns in observed data, build models that explain the world, and predict things without having explicit pre-programmed rules and models.
