Web21 apr. 2024 · $\begingroup$ So to clarify by "Cross validation is not necessary" I mean the cross_val_score function used. Test cv is of course necessary, but if no model selection or hyper-parameter tuning was done then there is no need to do 5 fold cv. $\endgroup$ Web3 aug. 2024 · If MSE -> 0, consequently RMSE -> 0, and r2 -> 1. But if RMSE -> +inf, MSE -> +inf and if MSE <= VAR (y) this will lead to r2 values lower Than 1 e.g. 0.2, 0.3, etc. So your results might place your analysis on the right track.

WebThe output of the function in maths is called range and input is called domain. We are using MSE in the linear regression because it is sensitive to the outliers and help in penalizing the parameters to get more accurate value that fits the training example (aka line of best fit). Web4 nov. 2024 · Additionally, MSE is a proper scoring rule, as compared to something like accuracy or AUC (I know we're talking about linear regression, but we could just as easily fit a logistic regression by minimizing the brier score. There are just problems with the gradient were we to do that). Lots of reasons to like MSE. – Demetri Pananos
the reason for the difference in values is that regressor.best_score_ is evaluated on a particular fold out of the 5-fold split that you do, whereas r2_score(y_pred = best.predict(X), y_true = y) evaluates the same model (regressor.best_estimator_) but on the full sample (including the (5-1)-fold sub-set that was used to train that ...
