您好,我读过了您Github上的源代码,有一个疑问:从代码看随机特征的选择是在构建每棵树的时候,而不是每棵树每一次分裂的时候。这好像和随机森林构建的方法有一些不同:我看到的资料里面是在随机森林中每棵树的每次分裂的时候都是选择的不同特征来进行分裂的?这一点有一点迷惑,恳请大佬指教,谢谢! 2020-02-02 ...

random forest algorithm was set to “balanced”, which penalises misclassification of the minority class (i.e. the positive samples)21. The remaining parameters of the random forest model were left to the default settings of thescikit-learnPython library (please refer to the “Random forest ...
We combined the random forest models for sleep–wake and wear-nonwear classification as presented in this paper to distinguish: Nonwear, Sleep, and Wake, and applied these to real-life (out of the lab) the accelerometer data. Total weekly napping time was calculated as the total duration of...
