Hi, I try to create some machine learning model for each stock in S&P500 index. When creating the model(Boosted tree model) I try to make it more successfully by doing hyper parameters using GridSearchCV. It takes so long to create one model so I don't want to think of creating all stocks models. I tried to work with CreateML and swift but it looks like it takes longer to run than sklearn on python. My question is how can I make the process faster? is there any hyper parameters on CreateML on swift (I couldn't find it at docs) and how can I run this code on my GPU? (should be much faster).
