python - How can I use "metrics.mutual_info" in scikit's feature.selection -
i use other scoring functions chi2
etc., not listed on page.
http://scikit-learn.org/stable/modules/feature_selection.html
http://scikit-learn.org/stable/modules/classes.html
for example metrics.mutual_info
, metrics.balanced_accuracy_score
how can integrate code?
thanks help
the new scikit-learn version 0.18, has added support mutual information feature selection. no need use metrics.mutual_info
. can use new feature_selection.mutual_info_classif score function in selectkbest
or selectpercentile
use chi2
.
x_new = selectkbest(mutual_info_classif, k=100).fit_transform(x, y)
for more information resent changes @ changelog.
