Fillers

The cesnet_tszoo package supports various ways of dealing with missing data in dataset. Possible config parameters in TimeBasedConfig, DisjointTimeBasedConfig and SeriesBasedConfig:

  • fill_missing_with: Can pass enum FillerType for built-in filler or pass a type of custom filler that must derive from Filler base class.
  • default_values: Default values for missing data, applied before fillers. Can set one value for all features or specify for each feature.

Note for TimeBasedConfig

Fillers can carry over values from the train set to the validation and test sets. For example, ForwardFiller can carry over values from previous sets.

Built-in fillers

The cesnet_tszoo package comes with multiple built-in fillers. To check built-in fillers refer to fillers.

Custom fillers

It is possible to create and use own fillers. But custom filler must derive from Filler base class.
