Classifying the order of classes rather than the classes themselves

I'm currently tackling a classification problem that needs prediction of the order of objects in a sequence, but not the object class itself. I've spent quite s

True Positive Rate and False Positive Rate (TPR, FPR) for Multi-Class Data in python [duplicate]

How do you compute the true- and false- positive rates of a multi-class classification problem? Say, y_true = [1, -1, 0, 0, 1, -1, 1, 0,
