They have to be from the same classes that were in previous batches, i.e. you need to know all the classes upfront. This is what the classes parameter on partial_fit is for. > 2) Will there be a interface for online learning in OnevsRestClassifier? If you care to implement it, then we're happy to accept a patch. Are you doing multi-label classification? ------------------------------------------------------------------------------ November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.
