ephasHi, if I use ROCEvaluation during cross validation, I am able to extract the mean AUC using ".mean".  I was wondering if there was a way to extract the tp/fp matrix you get from the get_ROC function, i.e. I am after the cross validated get_ROC matrix (I can only seem to extract the tp/fp matrix from the last fold and not the averaged matrix).  I hope this makes sense?16:08
ephasThe reason I am after this matrix is that I would like to draw an ROC curve from the cross validated results.16:09
ephasPS: I'm using the Python interface16:09
lisitsynephas: hey16:10
lisitsynyeah I got your problem16:10
lisitsynlet me check16:12
ephas@lisitsyn - thanks!16:12
lisitsynephas: you need averaged matrix right?16:13
ephasyes please16:14
lisitsynok this need some hack :(16:14
ephasrunning the .get_ROC function on the metric returns the matrix corresponding to the last fold16:14
ephasah - is the hack doable?16:15
lisitsyn.. in progress :)16:17
lisitsynlet me check again16:17
lisitsynephas: what about running it only once so that last fold is the only one?16:25
lisitsynand then again and again16:25
lisitsynthen manually compute mean ROC16:25
ephasI was thinking about that, but I couldn't work out how to calculate the mean matrix when the dimensions differ across folds (or is this consistent? ... I've not checked)16:28
lisitsynephas: I think they should match16:31
ephasok - I'll have a quick look and let you know how I get on16:32
ephasthanks for your help so far btw16:33
lisitsynnp, I'll try to help if any other issues occur16:34
