An online approach for feature selection for classification in big data Feature selection (FS), also known as attribute selection, is a process of selection of a subset of relevant features used in model construction. This process or method improves the classification accuracy by removing irrelevant...
也就是枚举特征集中的所有特征组合从而选出最优的特征子集,复杂度为O(2n)O(2n),因此实际应用中几乎不用。 启发式搜索 启发式搜索策略主要有序列前向选择(SFS,Sequential Forward Selection)和序列后向选择(SFS,Sequential Forward Selection)等。假定原始特征集是ff,挑选出来的特征子集是fsubfsub。序列前向搜索策略...

NCA Feature Selection for Regression The fsrnca function performs NCA feature selection modified for regression. Given n observations S={(xi,yi),i=1,2,…,n}, the only difference from the classification problem is that the response values yi∈ℝ are continuous. In this case, the aim is ...
特征选择 (feature_selection) [toc] 本文主要参考sklearn(0.18版为主,部分0.17)的1.13节的官方文档,以及一些工程实践整理而成。 当数据预处理完成后,我们需要选择有意义的特征输入机器学习的算法和模型进行训练。通常来说,从两个方面考虑来选择特征: 特征是否发散
