Web11 Apr 2024 · Now, we can estimate the performance of the model using cross_val_score(). We are using the r2 score here (What is R-squared in machine learning?). We will get the r2 score for each iteration of the k-fold cross-validation. We are printing the average r2 score. The output of the given program will be: R2: 0.9999999966902978 WebAn extra-trees regressor. This class implements a meta estimator that fits a number of randomized decision trees (a.k.a. extra-trees) on various sub-samples of the dataset and uses averaging to improve the predictive accuracy and control over-fitting.
