特征选择的代码示例如下,这里我们假设使用方差选择特征。 fromsklearn.feature_selectionimportVarianceThreshold# 选择方差大于0.1的特征selector=VarianceThreshold(threshold=0.1)selected_features=selector.fit_transform(features) 1. 2. 3. 4. 5. 该代码通过删除低方差的特征来进行特征选择。 步骤5:分类器训练 fromsk...
One typical step in many studies is feature extraction, however, there are not many tools focused on that aspect. In this paper, eeglib: a Python library for EEG feature extraction is presented. It includes the most popular algorithms when working with EEG and can be easily combined with ...
