Hey Guys,
I have 3 models I trained and I want to ensemble them together in hope of getting better results.
What is the best way of doing that:

Taking the softmaxes of each model and do averege
Taking the softmaxes and concatenating them and feeding it into Xgboost
Taking the last Linear output (not softmaxes) and feeding it into Xgboost
Other ways I don’t know about

Thanks in advance!
Yana
