Linear Regression with multiple Variables in Matlab

In the previous post I showed you how to implement Linear Regression with one Variable in Matlab.  In this one I’m going to discuss implementation with multiple variables. Before implementing multivariate Linear Regression, feature normalization would be the smart step since the gradient descent would converge (would find minimum cost function) much more quickly. Every sample value is ...

Feature Scaling in Python and Pandas DataFrame

Hire is a small script that i wrote long time ago to scale some of the features in order to get better performance and better prediction results in some ML algorithms. I used Python with Pandas to read in the CSV file and process feature values. Formulas for feature scaling used in the script can be found ...
