The method parameters (key-value pairs), which are a map of override parameters. Specify these parameters to override the default values. Related Time Series attributes do not accept aggregation parameters. The following list shows the parameters and their valid values for the "filling" featurization method for a Target Time Series dataset. Bold signifies the default value. -
aggregation: sum, avg, first, min, max -
frontfill: none -
middlefill: zero, nan (not a number), value, median, mean, min, max -
backfill: zero, nan, value, median, mean, min, max The following list shows the parameters and their valid values for a Related Time Series featurization method (there are no defaults): -
middlefill: zero, value, median, mean, min, max -
backfill: zero, value, median, mean, min, max -
futurefill: zero, value, median, mean, min, max To set a filling method to a specific value, set the fill parameter to value and define the value in a corresponding _value parameter.

- featurization_config.forecast_dimensions[]
- featurization_config.forecast_frequency
The frequency of predictions in a forecast. Valid intervals are an integer followed by Y (Year), M (Month), W (Week), D (Day), H (Hour), and min (Minute). For example, "1D" indicates every day and "15min" indicates every 15 minutes. You cannot specify a value that would overlap with the next larger frequency. That means, for example, you cannot specify a frequency of 60 minutes, because that is equivalent to 1 hour. The valid values for each frequency are the following: -
Minute - 1-59 -
Hour - 1-23 -
Day - 1-6 -
Week - 1-4 -
Month - 1-11 -
Year - 1 Thus, if you want every other week forecasts, specify "2W". Or, if you want quarterly forecasts, you specify "3M". The frequency must be greater than or equal to the TARGET_TIME_SERIES dataset frequency. When a RELATED_TIME_SERIES dataset is provided, the frequency must be equal to the TARGET_TIME_SERIES dataset frequency.
