Machine Learning with Python! Mean Squared Error (MSE)

Tutorial on how to calculate the mean squared error of model predictions. Learn different methods of calculating the mean squared error, graphing the prediction errors of a model and iterating over a parameter to minimize the MSE of a model.

Please note that the MSE formula notation at the top of the notebook is incorrect. 1/N is not included. The notebook on GitHub has been updated with the correction.

Also note the MSE was not calculated for the decision tree model predictions, but you can easily test it using the notebook by following the GitHub link below.
