AWS CLI Command Reference

[ aws . forecast ]

describe-auto-predictor

Description

Describes a predictor created using the CreateAutoPredictor operation.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-auto-predictor
--predictor-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--predictor-arn (string)

The Amazon Resource Name (ARN) of the predictor.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

PredictorArn -> (string)

The Amazon Resource Name (ARN) of the predictor

PredictorName -> (string)

The name of the predictor.

ForecastHorizon -> (integer)

The number of time-steps that the model predicts. The forecast horizon is also called the prediction length.

ForecastTypes -> (list)

The forecast types used during predictor training. Default value is [“0.1”,”0.5”,”0.9”].

(string)

ForecastFrequency -> (string)

The frequency of predictions in a forecast.

Valid intervals are Y (Year), M (Month), W (Week), D (Day), H (Hour), 30min (30 minutes), 15min (15 minutes), 10min (10 minutes), 5min (5 minutes), and 1min (1 minute). For example, “Y” indicates every year and “5min” indicates every five minutes.

ForecastDimensions -> (list)

An array of dimension (field) names that specify the attributes used to group your time series.

(string)

DatasetImportJobArns -> (list)

An array of the ARNs of the dataset import jobs used to import training data for the predictor.

(string)

DataConfig -> (structure)

The data configuration for your dataset group and any additional datasets.

DatasetGroupArn -> (string)

The ARN of the dataset group used to train the predictor.

AttributeConfigs -> (list)

Aggregation and filling options for attributes in your dataset group.

(structure)

Provides information about the method used to transform attributes.

The following is an example using the RETAIL domain:

{

"AttributeName": "demand",

"Transformations": {"aggregation": "sum", "middlefill": "zero", "backfill": "zero"}

}

AttributeName -> (string)

The name of the attribute as specified in the schema. 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 .

Transformations -> (map)

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. Default values are bolded.

  • 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" .

key -> (string)

value -> (string)

AdditionalDatasets -> (list)

Additional built-in datasets like Holidays and the Weather Index.

(structure)

Describes an additional dataset. This object is part of the DataConfig object. Forecast supports the Weather Index and Holidays additional datasets.

Weather Index

The Amazon Forecast Weather Index is a built-in dataset that incorporates historical and projected weather information into your model. The Weather Index supplements your datasets with over two years of historical weather data and up to 14 days of projected weather data. For more information, see Amazon Forecast Weather Index .

Holidays

Holidays is a built-in dataset that incorporates national holiday information into your model. It provides native support for the holiday calendars of 66 countries. To view the holiday calendars, refer to the Jollyday library. For more information, see Holidays Featurization .

Name -> (string)

The name of the additional dataset. Valid names: "holiday" and "weather" .

Configuration -> (map)

Weather Index

To enable the Weather Index, do not specify a value for Configuration .
