Python是否将类权重传递给SequentialFeatureSelector？

Question

from mlxtend.feature_selection import SequentialFeatureSelector as SFS

xgboost分类器

XGB = xgboost.XGBClassifier(num_class = 3)

设置要素选择

SFSres = SFS(XGB, k_features=8,cv=5)

尝试传递特征选择的类权重

SFSres = SFSres.fit(train_data, train_labels, fit_params={'sample_weight':weights})

结果

TypeError: fit() got an unexpected keyword argument 'fit_params'

如何将类权重传递给特征选择

Answer 1

"the documentation is incorrect and needs to be updated"

决定：

fit(train_data, train_labels, sample_weight=weights)
