Python Machine Learning Illustrated Guide For Beginners & Intermediates

In mathematical terms, you have input variable X and output variable y, and you have to find a function that captures relationship between the two i.e.
y= f(X)

Tom Mitchel from Carnegie Mellon University defined machine learning in mathematically understandable terms as in 1997. He said:
“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.”
