Unpredictable infinite loops in orngSVM.parameterSelection

Postby bgbg » Tue Apr 07, 2009 7:11

Hello,
In my experiments with SVM I want to select the best kernel/svm type combination. In order to do that, I exhaustively loop over all the possible combinations, perform orngSVM.parameterSelection on the learners and record the results.
However, several combinations of setup parameters and input data result in infinite loop. The most frustrating thing is that I cannot predict which combination will stuck infinitely.
Any comments?

Can you please post:
- which version of orange are you using (print orange.version)
- what data you are using
- can you print out the trace (parameters), or - even better - post the code, so we can trace out the bug.

Thanks!

I will try reconstructing this behavior with a code and data that does not expose my employee's IP and create an appropriate bug report.

(This might take me couple of days)
