CUSTOM Domain

The CUSTOM domain supports the following dataset types. For each dataset type, we list required and optional fields. For information on how to map the fields to columns in your training data, see Dataset Domains and Dataset Types.

TARGET_TIME_SERIES Dataset Type

The following fields are required:

  • item_id (string)

  • timestamp (timestamp)

  • target_value (floating-point integer) – This is the target field for which Amazon Forecast generates a forecast.

Ideally, only these required fields should be included. Other additional time series information should be included in a RELATED_TIME_SERIES dataset.

The following fields are required: :

  • item_id (string)

  • timestamp (timestamp)

In addition to the required fields, your training data can include other fields.

ITEM_METADATA Dataset Type

The following field is required:

  • item_id (string)

Although the following field is optional, Amazon Forecast suggests that you include it:

  • category (string)

In addition to the required and suggested optional fields, your training data can include other fields.
