WebMean squared error on the testing set: 2064.736 The raw MSE can be difficult to interpret. One way is to rescale the MSE by the variance of the target. This score is known as the R 2 also called the coefficient of determination. Indeed, this is the default score used in scikit-learn by calling the method score.
