LogisticRegression is a already multiclass classifier by default using the One vs Rest / All strategy by default (as implemented internally by liblinear which LogisticRegression is a wrapper of). So you don't need to use OneVsRest in this case.
If you want more info on multiclass reductions here is the doc: http://scikit-learn.org/stable/modules/multiclass.html > Is there a way to check how the normalization of the data is performed? What normalization? There is no normalization unless you do it yourself with one of those tools and a pipeline: http://scikit-learn.org/stable/modules/preprocessing.html -- Olivier ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
