Hi, Thomas,

the VotingClassifier can combine different models per majority voting amongst their predictions. Unfortunately, it refits the classifiers though (after cloning them). I think we implemented it this way to make it compatible to GridSearch and so forth. However, I have a version of the estimator that you can initialize with “refit=False” to avoid refitting if it helps. http://rasbt.github.io/mlxtend/user_guide/classifier/EnsembleVoteClassifier/#example-5-using-pre-fitted-classifiers

Best,
Sebastian

Is there a meta-estimator that can get as input a few precomputed MLPRegressors and give consensus predictions? Can the BaggingRegressor do this job using MLPRegressors as input?
