I am facing difficulty using the code. I am running Matlab 7, on Mac OS. When i call the function I get the following error :
??? Error using ==> vertcat
CAT arguments dimensions are not consistent.
Error in ==> statistics at 9
Error in ==> GA_feature_selector at 19
Is the output of the conditionalEntropy function a normalized value? I ask this because, I computed conditional entropy myself with the aid of MutualInformation function and MATLAB's entropy() method. I had got values of conditional Entropy to be greater than 1, which was expected. However, I am getting all conditional entropy values < 1 using InfoTheory toolbox's conditonalEntropy() function.
Has the output been normalized?
Please let me know. Thanks
Very useful and efficient toolbox, thank you. However, there is a bug in the nmi.m. last sentence should read:
z = sqrt((MI/Hx)*(MI/Hy));
Output variable is "z" and not "v". But this is obvious a typo, so it does not influence my rating.
