Description

Nowadays there are heaps of articles on the theory of fuzzy entropy and fuzzy mutual information. However, there is a clear significant lack for a Matlab implementation of these concepts. Based on numerous requests from students and researchers, I have prepared this code to simplify such concepts and give a tool that you can try directly. Of course, you may find heaps of different methods by which you may enhance the functionality of the code, so please feel free to inform me and the rest of any such updates overhere. Kindly, if you use this code then cite either of the following papers:

P.S: Let me know about bugs, if any.

Thank you very much Dr. Rami for sharing this great code

Updates
29 Aug 2011

The estimation of I_Cxx and I_xx have been updated into a better version now. Old versions are also included but commented for future use. If you find any bugs kindly let me know.

12 Mar 2012

I_xx estimation corrected with an example showing the values of I_xx and H_x when we have two completely redundant features.
