what is the proper usage of scale_pos_weight in xgboost

Oct 30, 2016 · For Example: Classes are A,B,C. So you can have binary classifier for classifying (A/Not A ) , another one would be (B/Not B). You can do this for 'n' number of classes. Then among all the probabilities corresponding to each classifier, you have to find a way to assign classes. $\endgroup$ – Harshit Mehta Feb 8 '19 at 16:48
