mRMR(min-redundancy max-relevance)的matlab程序

**********************************************************

To run the mRMR variable/feature selection for discrete 
variables, you need to add the path of mi_0.9 in your 
Matlab path. Then simply run mrmr_mid_d.m or mrmr_miq_d.m 
for your data.

If you have continuous data as input, you need to discretize 
the data first. Simple methods to do this can be thresholding 
at the mean or mean-plus/minus-std. Of course, you may also 
try the MI computation for continuous variables directly, as 
I showed in the my paper (below). However, typically the results 
are not as good as discrete variables.

Note that this version is old and uses double-precision 
in mutual information computation, thus the feature selection
results may be slightly different if you also compare the 
against those produced by the newer C versions downloadable
from our website. The C versions uses single precision for
floating numbers to save some memories.

The codes cannot be re-distributed without permission from 
the author, Hanchuan Peng.
