case class ObjectiveParams(objective: String, fobj: Option[FObjTrait]) extends Serializable with Product

Defines parameters related to the lightgbm objective function.

objective

The Objective. For regression applications, this can be: regression_l2, regression_l1, huber, fair, poisson, quantile, mape, gamma or tweedie. For classification applications, this can be: binary, multiclass, or multiclassova.

fobj

Customized objective function. Should accept two parameters: preds, train_data, and return (grad, hess).
