I noticed that xboost, which I believe is the Graph Lab impelmenation of boosted trees, takes a range objective function. It seems that some of these like reg:linear, reg:logistic would are set depending on whether I use a boosted tree classifier or a regression . However, there are some other like count:poisson, multi:softmax, multi:softprob, custom rank:pairwise or potentially a customised loss function that are not exposed by Graph Lab create.
Any plans to expose the objective function in later releases? I
