Machine Learning Algorithms from Start to Finish in Python: Linear Regression

Probably one of the most common algorithms around, Linear Regression is a must know for Machine Learning Practitioners. This is usually a beginner's first exposure to a real Machine Learning algorithm, and knowing how it operates on a deeper level is crucial to gain a better understanding of it. So, briefly, let's break down the real question; What really is Linear Regression? Linear Regression is a supervised learning algorithm that aims at taking a linear approach at modelling the relation between a dependent variable and an independent variable. In other words, It aims to fit a linear trendline that best captures the relationship of the data, and, from this line, it can predict what the target values may be.
