Choosing the Best Tree-Based Method for Predictive Modeling

WebGradient Boosting for regression. This estimator builds an additive model in a forward stage-wise fashion; it allows for the optimization of arbitrary differentiable loss functions. In each stage a regression tree is fit on the negative gradient of the given loss function. 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. simply the kids blogspot https://stankoga.com
