Retrieve the residual deviance If "train", "valid", and "xval" parameters are FALSE (default), then the training residual deviance value is returned. If more than one parameter is set to TRUE, then a named vector of residual deviances are returned, where the names are "train", "valid" or "xval".
h2o.residual_deviance(object, train = FALSE, valid = FALSE, xval = FALSE)
Retrieve the training residual deviance
Retrieve the validation residual deviance
Retrieve the cross-validation residual deviance
