If we have multi-class classification problem, like 3 classes in logistic regression, how model will categorize the classes?if we see the sigmoid curve there we see just s shaped curve which represent two classes.

Hi @ashokasr143,

In this case, you can use ‘one-versus-all’ method. For example, if you have three classes A, B and C, you can first classify as A or not A(B and C). And repeat the same with B and C.
