WebMar 23, 2024 · It works only for Linear Regression and not any other algorithm. Normal Equation is the Closed-form solution for the Linear Regression algorithm which … WebIn Module 2, we gave the normal equation (i.e., closed-form solution) for linear regression using MSE as the cost function. Prove that the closed-form solution for Ridge Regression is w = (21 + XT ·X)-1.xt.y, where I is the identity matrix, X = (x(1), x(2), ...,x(m))T is the input data matrix, x(i) (1, X1, X2, ... , Xn) is the i-th data sample ...
