Gradient Boosting – A Concise Introduction from Scratch

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 gradient-boosted trees; it usually outperforms random forest. A gradient-boosted trees … WebGradient boosting is a machine learning technique that makes the prediction work simpler. It can be used for solving many daily life problems. However, boosting works best in a given set of constraints & in a given set of situations. The three main elements of this boosting method are a loss function, a weak learner, and an additive model.
