【机器学习】特征选择(Feature Selection)方法汇总 孙佳伟 特征选择之-CFS(Correlation-based Feature Selection) 文章:Correlation-based Feature Selection for Discrete and Numeric Class Machine Learning CFS是能确定所选子集特征个数的特征选择方法,其估计特征子集并对特征子集而不是单个特征进… 刘嘟嘟打开...
特征选择(feature selection)是查找和选择数据集中最有用特征的过程,是机器学习流程中的一大关键步骤。不必要的特征会降低训练速度、降低模型可解释性,并且最重要的是还会降低其在测试集上的泛化表现。 目前存在一些专用型的特征选择方法,我常常要一遍又一遍地将它们应用于机器学习问题,这实在让人心累。所以我用Python构...
