Arthur Samuel described it as: "the field of study that gives computers the ability to learn without being explicitly programmed."
machine learning new definition
Tom Mitchell provides a more modern definition: "A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P, if its performance at tasks in T, as measured by P, improves with experience E."

what is supervised learning
In supervised learning, we are given a data set or training data and already know what our correct output should look like, having the idea that there is a relationship between the input and the output.
In a regression problem, we are trying to predict results within a continuous output, meaning that we are trying to map input variables to some continuous function.Definition
