Gradient boosting is a machine learning technique used in regression and classification tasks, among others. It gives a prediction model in the form of an ensemble of weak prediction models, which are typically decision trees. When a decision tree is the weak learner, the resulting algorithm is called … See more The idea of gradient boosting originated in the observation by Leo Breiman that boosting can be interpreted as an optimization algorithm on a suitable cost function. Explicit regression gradient boosting algorithms … See more (This section follows the exposition of gradient boosting by Cheng Li. ) Like other boosting methods, gradient boosting combines weak "learners" into a single strong … See more Gradient boosting is typically used with decision trees (especially CARTs) of a fixed size as base learners. For this special case, Friedman proposes a modification to gradient boosting … See more Gradient boosting can be used in the field of learning to rank. The commercial web search engines Yahoo and Yandex use variants of gradient … See more In many supervised learning problems there is an output variable y and a vector of input variables x, related to each other with some probabilistic distribution. The goal is to find some function $${\displaystyle {\hat {F}}(x)}$$ that best approximates the … See more Fitting the training set too closely can lead to degradation of the model's generalization ability. Several so-called regularization techniques … See more The method goes by a variety of names. Friedman introduced his regression technique as a "Gradient Boosting Machine" (GBM). Mason, Baxter et al. described the generalized abstract class of algorithms as "functional gradient boosting". … See more WebThe name gradient boosting machines come from the fact that this procedure can be generalized to loss functions other than MSE. Gradient boosting is considered a gradient descent algorithm. Gradient descent …
