Multi label implement #13

Closed emma-sjwang closed 6 years ago

I wonder how to realize multi label classification task using this binary classification MISVM.

Sorry for the delay in responding. This might depend on the assumptions that you make for how bag and instance labels are related. For example, a multi-class instance problem would imply a multi-label bag-level problem under the standard MIL assumption.

In any case, you could probably use a one-vs-rest classification scheme: treat each class as a separate binary problem, train a classifier for each, then recombine the outputs of the resulting classifiers to determine which of the multiple classes each bag or instance belongs to.

Thanks a lot.
