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.
