So M S E ( Y ^) = 1 N ∑ i N ( y i − y ^ i) 2 Now if we square we have something called Root Mean Square Error. This is something that could be interpratate as “average error” the same way we interpratate standard deviation as average deviation. R M S E ( Y ^) = 1 N ∑ i N ( y i − y ^ i) 2 Webbprint(‘Root Mean Squared Error:’, np.sqrt(metrics.mean_squared_error(y_test, y_pred))) R Squared score (R2) Explains in percentage terms the amount of variation in the response variable that is due to variation in the feature variables. sample network security resume
