SolutionVersion - Amazon Personalize

SolutionVersion

An object that provides information about a specific version of a Solution.

Contents

creationDateTime

The date and time (in Unix time) that this version of the solution was created.

Type: Timestamp

Required: No

datasetGroupArn

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

Type: String

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.

Type: String

Length Constraints: Maximum length of 256.

Required: No

failureReason

If training a solution version fails, the reason for the failure.

Type: String

Required: No

lastUpdatedDateTime

The date and time (in Unix time) that the solution was last updated.

Type: Timestamp

Required: No

performAutoML

When true, Amazon Personalize searches for the most optimal recipe according to the solution configuration. When false (the default), Amazon Personalize uses recipeArn.

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 in the solution.

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

solutionVersionArn

The ARN of the solution version.

Type: String

Length Constraints: Maximum length of 256.

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

Required: No

status

The status of the solution version.

A solution version can be in one of the following states:

  • CREATE PENDING

  • CREATE IN_PROGRESS

  • ACTIVE

  • CREATE FAILED

Type: String

Length Constraints: Maximum length of 256.

Required: No

trainingHours

The time used to train the model. You are billed for the time it takes to train a model. This field is visible only after Amazon Personalize successfully trains a model.

Type: Double

Valid Range: Minimum value of 0.

Required: No

trainingMode

The scope of training used to create the solution version. The FULL option trains the solution version based on the entirety of the input solution's training data, while the UPDATE option processes only the training data that has changed since the creation of the last solution version. Choose UPDATE when you want to start recommending items added to the dataset without retraining the model.

Important

The UPDATE option can only be used after you've created a solution version with the FULL option and the training solution uses the HRNN-Coldstart Recipe (Legacy).

Type: String

Valid Values: FULL | UPDATE

Required: No

tunedHPOParams

If hyperparameter optimization was performed, contains the hyperparameter values of the best performing model.

Type: TunedHPOParams object

Required: No
