WebFor a regression model, the predicted value based on X is returned. score(X, y) ¶ Returns the coefficient of determination R^2 of the prediction. The coefficient R^2 is defined as (1 - u/v), where u is the regression sum of squares ( (y - y_pred) ** 2).sum () and v is the residual sum of squares ( (y_true - y_true.mean ()) ** 2).sum ().

WebApr 8, 2024 · Decision trees are a non-parametric model used for both regression and classification tasks. The from-scratch implementation will take you some time to fully understand, but the intuition behind the algorithm is quite simple.

WebIn a gradient-boosting algorithm, the idea is to create a second tree which, given the same data data, will try to predict the residuals instead of the vector target. We would therefore have a tree that is able to predict the errors made by the initial tree. Let’s train such a tree. residuals = target_train - target_train_predicted tree ...
