Gradient boosting machine中文

WebBoost是"提升"的意思,一般Boosting算法都是一个迭代的过程,每一次新的训练都是为了改进上一次的结果,这要求每个基学习器的方差足够小,即足够简单(weak machine),因为Boosting的迭代过程足以让bias减小, … 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.
