Solution

Important

After you create a solution, you can’t change its configuration. By default, all new solutions use automatic training. With automatic training, you incur training costs while your solution is active. You can't stop automatic training for a solution. To avoid unnecessary costs, make sure to delete the solution when you are finished. For information about training costs, see Amazon Personalize pricing.

An object that provides information about a solution. A solution includes the custom recipe, customized parameters, and trained models (Solution Versions) that Amazon Personalize uses to generate recommendations.

After you create a solution, you can’t change its configuration. If you need to make changes, you can clone the solution with the Amazon Personalize console or create a new one.

creationDateTime

The creation date and time (in Unix time) of the solution.

Type: Timestamp

Required: No

datasetGroupArn

The Amazon Resource Name (ARN) of the dataset group that provides the training data.

Length Constraints: Maximum length of 256.

Pattern: arn:([a-z\d-]+):personalize:.*:.*:.+

Required: No

eventType

The event type (for example, 'click' or 'like') that is used for training the model. If no eventType is provided, Amazon Personalize uses all interactions for training with equal weight regardless of type.

Type: String

Length Constraints: Maximum length of 256.

Required: No

lastUpdatedDateTime

Required: No

name

The name of the solution.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 63.

Pattern: ^[a-zA-Z0-9][a-zA-Z0-9\-_]*

performAutoML
Important

We don't recommend enabling automated machine learning. Instead, match your use case to the available Amazon Personalize recipes. For more information, see Determining your use case.

When true, Amazon Personalize performs a search for the best USER_PERSONALIZATION recipe from the list specified in the solution configuration (recipeArn must not be specified). When false (the default), Amazon Personalize uses recipeArn for training.

Type: Boolean

Required: No

performAutoTraining

Specifies whether the solution automatically creates solution versions. The default is True and the solution automatically creates new solution versions every 7 days.

For more information about auto training, see Creating and configuring a solution.

Type: Boolean

Required: No

performHPO

Whether to perform hyperparameter optimization (HPO) on the chosen recipe. The default is false.

Type: Boolean

Required: No

recipeArn

The ARN of the recipe used to create the solution. This is required when performAutoML is false.

Type: String

Length Constraints: Maximum length of 256.

Pattern: arn:([a-z\d-]+):personalize:.*:.*:.+

Required: No

solutionArn

The ARN of the solution.

Type: String

Length Constraints: Maximum length of 256.

Pattern: arn:([a-z\d-]+):personalize:.*:.*:.+

Required: No

solutionConfig

Describes the configuration properties for the solution.

Type: SolutionConfig object

Required: No

status

The status of the solution.

A solution can be in one of the following states:

  • CREATE PENDING > CREATE IN_PROGRESS > ACTIVE -or- CREATE FAILED

  • DELETE PENDING > DELETE IN_PROGRESS

Type: String

Length Constraints: Maximum length of 256.

Required: No
