case class SeedParams(seed: Option[Int], deterministic: Option[Boolean], baggingSeed: Option[Int], featureFractionSeed: Option[Int], extraSeed: Option[Int], dropSeed: Option[Int], dataRandomSeed: Option[Int], objectiveSeed: Option[Int], boostingType: String, objective: String) extends ParamGroup with Product with Serializable

Defines parameters related to seed and determinism for lightgbm.

seed

Main seed, used to generate other seeds.

deterministic

Setting this to true should ensure stable results when using the same data and the same parameters.

baggingSeed

Bagging seed.

featureFractionSeed

Feature fraction seed.

extraSeed

Random seed for selecting threshold when extra_trees is true.

dropSeed

Random seed to choose dropping models. Only used in dart.

dataRandomSeed

Random seed for sampling data to construct histogram bins.

objectiveSeed

Random seed for objectives, if random process is needed. Currently used only for rank_xendcg objective.

boostingType

Boosting type, used to determine if drop seed should be set.

objective

Objective, used to determine if objective seed should be set.
