Overview
When passing FeaturizationMethod as input to an Aws::Client method, you can use a vanilla Hash:
{
featurization_method_name: "filling", # required, accepts filling
featurization_method_parameters: {
"ParameterKey" => "ParameterValue",
},
}
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"}
}
Instance Attribute Summary collapse
-
#featurization_method_name ⇒ String
The name of the method.
-
#featurization_method_parameters ⇒ Hash<String,String>
The method parameters (key-value pairs), which are a map of override parameters.
Instance Attribute Details
#featurization_method_name ⇒ String
The name of the method. The \"filling\" method is the only supported method.
Possible values:
- filling
#featurization_method_parameters ⇒ Hash<String,String>
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.

The following list shows the parameters and their valid values for a Related Time Series featurization method (there are no defaults):

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"
.
