- disr(X, y, **kwargs)
- This function implement the DISR feature selection.
The scoring criteria is calculated based on the formula j_disr=sum_j(I(f,fj;y)/H(f,fj,y))
Input
-----
X: {numpy array}, shape (n_samples, n_features)
input data, guaranteed to be a discrete data matrix
y: {numpy array}, shape (n_samples,)
input class labels
kwargs: {dictionary}
n_selected_features: {int}
number of features to select
Output
------
F: {numpy array}, shape (n_features, )
index of selected features, F[1] is the most important feature
