[jira] [Updated] (IGNITE-7025) Implement different strategies to
fill missed data in LabeledDataset during loading from file
[ https://issues.apache.org/jira/browse/IGNITE-7025?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aleksey Zinoviev updated IGNITE-7025:
-------------------------------------
Description:
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
}
