In this section, you will learn to use the Multiple Linear Regression model in Python to predict house prices based on features from theCalifornia Housing Dataset. You’ll learn how to preprocess data, fit a regression model, and evaluate its performance while addressing common challenges like mul...

In ML, we write the equation for a linear regression model as follows: y′=b+w_1x_1 where: y′ is the predicted label—the output. b is thebiasof the model. Bias is the same concept as the y-intercept in the algebraic equation for a line. In ML, bias is sometimes referred to...
