Method Detail

foldCol

Param<String> foldCol()

Param for the column name of user specified fold number. Once this is specified, CrossValidator won't do random k-fold split. Note that this column should be integer type with range [0, numFolds) and Spark will throw exception on out-of-range fold numbers.

Returns:

(undocumented)

getFoldCol

String getFoldCol()

getNumFolds

int getNumFolds()

numFolds

IntParam numFolds()

Param for number of folds for cross validation. Must be >= 2. Default: 3

Returns:

(undocumented)
