Question about if about pdtb3 HOT 4 CLOSED

Thanks! Could you elaborate? To me it seems that if random_sections is True, you go to the else statement and get randomly shuffled section ordering (for xval). If it is False, you go to the first if and get a fixed section ordering (for xval) every time, starting from the case where dev has sections 0 & 1.

Let me know if you think otherwise!

Thank you for the reply. My understanding is that the default value for random_sections is False, so if not random_selection, it means true, you go to the if part, and the else part means random_selection is false. (???)

from pdtb3.

Yes, because the default is random_sections=False the default behavior is following the first if. The else part is followed when random_sections is True, not False.

You can read the if/else in the code as:

if not random_sections: 
   fixed split
elif random_sections:
   random split

does this make sense?

Ah, I see. Thank you very much for the clarification.
