[R] GA/SWARM Hyperparameter (HP) Optimisation for Classification based Machine Learning

[Alexander Gracian]

Hi,
I believe that Caret uses a  grid-serach approach. I was wondering if:
1 There are more efficient implementations for HP tuning for classification algos (eg XGboost, CatBoost, SVM, RF etc), using say GM/SWARM approaches, akin to Google's approach AutoML for Image related Net problems?
2 This one is most probably wishful thinking, but is anyone looking at GM/SWARM at HP tuning across models (ensemble models). eg the best set of HP for combined XGBoost + SVM, which accounts for the correlation/interaction of the prediction assumptions.
