# of Trees needed

[hrstoyanov]

I see that in table Paragraph 5, page 7, FTDRF with 500 trees achieves almost the same accuracy as FTDRF with 2000 trees and gcForest with 4000 trees. Do you have any thoughts on this apparent overcapacity and how one can come up with the most economical model? Thanks

Btw, thank you and @kingfengji for publishing such interesting alternatives to DNNs.
