WebApr 24, 2024 · Scikit learn is a machine learning toolkit for Python. As such, it has tools for performing steps of the machine learning process, like training a model. The scikit learn ‘fit’ method is one of those tools. The ‘fit’ method trains the algorithm on the training data, after the model is initialized. That’s really all it does. WebApr 11, 2024 · 简单来说，集成学习是一种分类器结合的方法（不是一种分类器）。 宏观上讲集成学习 分为3类 ： 序列集成方法boosting 思路：每个学习器按照串行的方法生成。 把几个基本学习器层层叠加，但是每一层的学习器的重要程度不同，越前面的学习的重要程度越高。 它聚焦 样本的权重 。 每一层在学习的时候，对前面几层分错的样本“特别关注”，建立了 …
