For example, you could define a class that does everything that Python’s built-in lists do, and then add an additional method or methods based on your needs. 例如,您可以定义一个类来完成Python内置列表所做的一切,然后根据需要添加一个或多个附

简单来说,数据降维(dimensionality reduction)就是只选择一些特征作为输入,或者合并特征后输入模型的特征。因为过多的特征会导致模型预测准确率下降或者过拟合(overfitting)。一般常用的特征选择主要分为三类:Filter Methods,Wrapper Methods,Embeded Methods。因为特征选择不是本文重点,有兴趣的同学可以阅读这篇文章。
