Machine Learning : Regression Analysis #1
Introduction If you are aspiring to become a data scientist, regression will be the first algorithm you will learn. It is one of the most well known and easiest algorithm in machine learning. Learning about regression analysis would not only help you to clear job interviews but also to solve real-world problems. This article would mainly focus on Linear Regression, which is a form of regression. What is Regression? Regression is a statistical technique which is used to predict continuous dependent variable given a set of independent variables. Regression Analysis takes certain criteria(we will discuss in another post) to work properly. However, if the criteria are met, the algorithm gives splendid results. Mathematically, linear regression is a function in the form, y = a0 + a1x1 + a2x2+....aNxN where y is the dependent variable, x1,x2,x3...xN are the independent variable or features wit...
