Aleksey Zinoviev updated IGNITE-7025:
-------------------------------------
Description:
For example, it can be four strategies
* Fill missed value with zero or empty string or default value for categorical
features = ZERO
* Fill missed value with mean on column/Requires an additional time to
calculate = MEAN
* Fill missed value with mode on column. Requires an additional time to
calculate = MODE
* Deletes observation with missed values. Transforms dataset and changes
indexing = DELETE
was:
For example, it can be four strategies
public enum FillMissingValueWith {
* /**
* Fill missed value with zero or empty string or default value for
categorical features
*/
ZERO,
/**
* Fill missed value with mean on column
* Requires an additional time to calculate
*/
MEAN,
/**
* Fill missed value with mode on column
* Requires an additional time to calculate
*/
MODE,
/**
* Deletes observation with missed values
* Transforms dataset and changes indexing
*/
DELETE
