Hi

I have a question about running feature selection algorithms of weka in matlab

does Any body know how i can change the option of a feature selection algorithm of weka in matlab? for example i want to decrease the criteria of error to select more features.

Thanks

The easiest way to do this is that:

1. save your attributes in a excel file

2, save the excel file in CSV format

3,open CSV file in matlab

4, copy the data into a txt file 

5 add the headers at he beginning of the file

6 save the file as .arff

Thank you :) I have programed the creation of arf file automatically with a function 

Hi Khadidja can u pls share the function for the conversion
