Multiple Linear Regression in Machine Learning

A couple of weeks ago I wrote an article on simple linear regression, which I would recommend reading before proceeding to read this one. Machine learning is a very interesting topic and I have been studying it on my free time. I hope this article sparks your interest in the subject or helps continue fuel it. In simple linear regression there is a one-to-one relationship between the input variable and the output variable. But in multiple linear regression, as the name implies there is a many-to-one relationship, instead of just using one input variable, you use several.
