How to use ReliefF algorithm for a dataset?

20 views (last 30 days)
I want to use ReliefF feature selection algorithm for a dataset(colon), I found this code for ReliefF function from github website (I attached two file ReliefF_Zeal and test_ReliefF) and also Matlab Help is similar to this code
function [Rank, Score] = ReliefF_Zeal(X, y, K)
[Rank, Score] = relieff(X, y, K);
but I don't know how to load my data (train and test) in this function, my goal was selecting 30 best features from the data,I'll be very gratefull to have your opinions. Thanks

I am also interested about Relief-F for a project and as I understood x is your input data, y is the target, k is a number can be 10(as I understood it depends on your data). But X must have as many rows as there are elements in Y.
