hi all,
Im using the SelectPercentile function with chi2 feature selection in an
NLP task. I have created a sparse matrix using the feature extraction
techniques in sklearn. However, when I do the feature selection it thows a
warning saying:
"UserWarning: Duplicate scores. Result may depend on feature ordering.There
are probably duplicate features, or you used a classification score for a
regression task."
Can anyone explain what does this mean? Am I doing something wrong?
