how to cross validate own operators
Learner III
hi
I've made a few my own operators that do classification together and create a model in end of my process. when execute these operators,it work properly but when i put these operators in a x-validation operator, it just work properly on fold1 and on other folds my algorithm shows Strange behavior. in fact it do not give error but works wrong.
For a while my thesis, stuck.Can anyone suggest me a solution.
thanx

you can add breakpoints before/after each of your operators in the x-validation subproccess and check what data is recieved/sent from each one. Maybe that helps you figuring out what is wrong.
From a technical point of view, there is nothing special about x-val. However you may want to check that your operators do not modify the original data when being executed, otherwise each subsequent execution will work on data changed by the previous iterations.
