Gradient Boosting

Gradient boosting ensemble technique for regression

Gradient boosting is a machine learning technique for regression and classification  problems, which produces a prediction model in the form of an ensemble of weak prediction models, typically decision trees. It builds the model in a stage-wise fashion like other boosting methods do, and it generalizes them by allowing optimization of an arbitrary differentiable loss function.
