Properties

creationDateTime DateTime
The date and time (in Unix time) that this version of the solution was created.
@UnixDateTimeConverter(), @JsonKey(name: 'creationDateTime'), final
datasetGroupArn String
The Amazon Resource Name (ARN) of the dataset group providing the training data.
@JsonKey(name: 'datasetGroupArn'), final
eventType String
The event type (for example, 'click' or 'like') that is used for training the model.
@JsonKey(name: 'eventType'), final
failureReason String
If training a solution version fails, the reason for the failure.
@JsonKey(name: 'failureReason'), final
hashCode int
The hash code for this object. [...]
read-only, inherited
lastUpdatedDateTime DateTime
The date and time (in Unix time) that the solution was last updated.
@UnixDateTimeConverter(), @JsonKey(name: 'lastUpdatedDateTime'), final
performAutoML bool
When true, Amazon Personalize searches for the most optimal recipe according to the solution configuration. When false (the default), Amazon Personalize uses recipeArn.
@JsonKey(name: 'performAutoML'), final
performHPO bool
Whether to perform hyperparameter optimization (HPO) on the chosen recipe. The default is false.
@JsonKey(name: 'performHPO'), final
recipeArn String
The ARN of the recipe used in the solution.
@JsonKey(name: 'recipeArn'), final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
solutionArn String
The ARN of the solution.
@JsonKey(name: 'solutionArn'), final
solutionConfig SolutionConfig
Describes the configuration properties for the solution.
@JsonKey(name: 'solutionConfig'), final
solutionVersionArn String
The ARN of the solution version.
@JsonKey(name: 'solutionVersionArn'), final
status String
The status of the solution version. [...]
@JsonKey(name: 'status'), final
trainingHours double
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.
@JsonKey(name: 'trainingHours'), final
trainingMode 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. The UPDATE option can only be used after you've created a solution version with the FULL option and the training solution uses the native-recipe-hrnn-coldstart.
@JsonKey(name: 'trainingMode'), final
tunedHPOParams TunedHPOParams
If hyperparameter optimization was performed, contains the hyperparameter values of the best performing model.
@JsonKey(name: 'tunedHPOParams'), final
