class Aws::ForecastService::Types::FeaturizationMethod
Provides information about the method that featurizes (transforms) a dataset field. The method is part of the `FeaturizationPipeline` of the Featurization
object.
The following is an example of how you specify a `FeaturizationMethod` object.
`{`
`“FeaturizationMethodName”: “filling”,`
`“FeaturizationMethodParameters”: {“aggregation”: “sum”, “middlefill”: “zero”, “backfill”: “zero”}`
`}`
@note When making an API call, you may pass FeaturizationMethod
data as a hash: { featurization_method_name: "filling", # required, accepts filling featurization_method_parameters: { "ParameterKey" => "ParameterValue", }, }
@!attribute [rw] featurization_method_name
The name of the method. The "filling" method is the only supported method. @return [String]
@!attribute [rw] featurization_method_parameters
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. For example, to set backfilling to a value of 2, include the following: `"backfill": "value"` and `"backfill_value":"2"`. @return [Hash<String,String>]
