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.
