> I assume that you want to tell that it is not wise to compute TP, FP, FN and then precision and recall using cross_val_predict. If this is what you mean, I'd like you to explain why.
Because if there is high variance as a function of training set rather than test sample I'd like to know. > The pooled mean is the correct metric in this case. I don't think we are in agreement on that.
