case class DatasetParams(isEnableSparse: Option[Boolean], useMissing: Option[Boolean], zeroAsMissing: Option[Boolean]) extends ParamGroup with Product with Serializable
Defines the Dataset parameters passed to the LightGBM classifier.
- isEnableSparse
Used to enable/disable sparse optimization.
- useMissing
Set this to false to disable the special handle of missing value.
- zeroAsMissing
Set to true to treat all zero as missing values (including the unshown values in LibSVM/sparse matrices) Set to false to use na for representing missing values.
