Class Featurization

java.lang.Object

software.amazon.awssdk.services.forecast.model.Featurization

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<Featurization.Builder,Featurization>

@Generated("software.amazon.awssdk:codegen")
public final class Featurization
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Featurization.Builder,Featurization>

This object belongs to the CreatePredictor operation. If you created your predictor with CreateAutoPredictor, see AttributeConfig.

Provides featurization (transformation) information for a dataset field. This object is part of the FeaturizationConfig object.

For example:

{

"AttributeName": "demand",

FeaturizationPipeline [ {

"FeaturizationMethodName": "filling",

"FeaturizationMethodParameters": {"aggregation": "avg", "backfill": "nan"}

} ]

}

Method Detail

attributeName

public final String attributeName()

The name of the schema attribute that specifies the data field to be featurized. Amazon Forecast supports the target field of the TARGET_TIME_SERIES and the RELATED_TIME_SERIES datasets. For example, for the RETAIL domain, the target is demand, and for the CUSTOM domain, the target is target_value. For more information, see howitworks-missing-values.

Returns:

The name of the schema attribute that specifies the data field to be featurized. Amazon Forecast supports the target field of the TARGET_TIME_SERIES and the RELATED_TIME_SERIES datasets. For example, for the RETAIL domain, the target is demand, and for the CUSTOM domain, the target is target_value. For more information, see howitworks-missing-values.

hasFeaturizationPipeline

public final boolean hasFeaturizationPipeline()

For responses, this returns true if the service returned a value for the FeaturizationPipeline property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

featurizationPipeline

public final List<FeaturizationMethod> featurizationPipeline()

An array of one FeaturizationMethod object that specifies the feature transformation method.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFeaturizationPipeline() method.

Returns:

An array of one FeaturizationMethod object that specifies the feature transformation method.
