WebbOne 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. regressor.score(data_test, target_test) 0.6872520581075487 WebbThe minimum weighted fraction of the sum total of weights (of all the input samples) required to be at a leaf node. Samples have equal weight when sample_weight is not provided. max_features{“sqrt”, “log2”, None}, int or float, default=1.0. The number of features to consider when looking for the best split:
