Hi @zizoo -

Did you see this post from last week?

Metrics in multiclass classification

Hi @zizoo - Sorry for the delayed response here. One method you’ll find mentioned a lot for evaluating the results of multi-class classifiers is the F-measure (or F1), both micro- and macro- averaged. There a brief explanation and associated calculation in this thread on CrossValidated. Scikit-learn has a function that will calculate it for you. Incidentally, macro-averaged F1 is what Amazon ML uses. There are also some methods to calculate multi-class ROC curves using pairwise comparison, whe…
