Cant run the code

[awalece04ku]

Many thanks for the code.
I got an error due to missing functions.

Can you please upload an example of the code so that users can find it more useful?
Thanks in advance.

Dear @awalece04ku
I believe the missing function is the muteinf. You can find it at https://www.mathworks.com/matlabcentral/fileexchange/56937-feature-selection-library.

I hope this helps you.

Best regards,
Artur Jordão.

Dear Artur
I have used that function. Still got error on that line. I got all NAN value after executing line 86 of infFSs

Could you send me the data and the parameters (i.e., alpha) you are using?

[awalece04ku]

Dear Artur
please unzip data.zip file.

Many thanks in advance for your time and effort in investigating the error.
Also please suggest any modification so that I can run.

data.zip

the line i executed as follows.
load('data.mat')
[RANKED, WEIGHT, SUBSET] = InfFS_S(X,Y, alpha);

Dear @awalece04ku,

I see the problem. Your labels are in an incorrect format. Try this before calling InfFS_S(X, Y, alpha):
Y = randi([0, 1], [size(Y, 1), 1]);
Y(find(Y==0)) = -1;

In summary, the labels need to be between -1 and 1. For example, see "[length(find(Y==+1)) length(find(Y==-1))] / n;" in the muteinf function.

Unfortunately, I believe the current source code (InfFS_S) does not support multiclass problems. Thus, in the current form, InfFS_S is not suitable for your data as your labels present three categories.

I hope this helps you.
Best Regards,
Artur Jordão.

Many thanks, Artur, for your time and effort.
I now got the problem.
Hope Author @giorgioroffo will provide solutions for multiclass problems.
