Method Detail

getMaxCategories

int getMaxCategories()

handleInvalid

Param<String> handleInvalid()

Param for how to handle invalid data (unseen labels or NULL values). Note: this param only applies to categorical features, not continuous ones. Options are: 'skip': filter out rows with invalid data. 'error': throw an error. 'keep': put invalid data in a special additional bucket, at index of the number of categories of the feature. Default value: "error"

Specified by:

handleInvalid in interface HasHandleInvalid

Returns:

(undocumented)

maxCategories

IntParam maxCategories()

Threshold for the number of values a categorical feature can take. If a feature is found to have > maxCategories values, then it is declared continuous. Must be greater than or equal to 2.

(default = 20)

Returns:
