Linear Regression (Gradient Descent Method) If you don't have any idea of Gradient Descent Algorithm , please check our previous post , there I have explained Gradient Descent Algorithm very well explained in brief. Now moving toward our current topic Linear Regression . In the previous post , we have just discussed the theory behind the Gradient Descent . Today we will learn Linear Regression where we will use Gradient Descent to minimize the cost function. WHAT IS LINEAR REGRESSION: Suppose you are given a equation: y=2x1+3x2+4x3+1 and you are said to find the value at any point (1,1,1) corresponds to x1, x2, x3 respectively. You'll simply put the value of x1, x2, x3 into equation and tell me the answer :10,Right? But What if you are given different set of (x1, x2, x3,y) and you are said to find the equation. Here's what,Linear Regression Comes into picture.It helps us to find out or fit a Linear equation to datasets given. Above equation can be easily tra...
