Interesting question. There are general techniques for extending from binary classification to
-category one. For instance, one simple approach (one-versus-all decomposition) is to form the following yes/no questions: "Does an example belong to category k or not?" If the machine learns
hypotheses that answer each of the
questions correctly, you can combine the answers to form a multi-category prediction. Hope this helps.
