describe-solution

Description

Describes a solution. For more information on solutions, see CreateSolution .

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

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

Options

--solution-arn (string)

The Amazon Resource Name (ARN) of the solution to describe.

--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.

Output

solution -> (structure)

An object that describes the solution.

name -> (string)

The name of the solution.

solutionArn -> (string)

The ARN of the solution.

performHPO -> (boolean)

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

performAutoML -> (boolean)

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.

recipeArn -> (string)

The ARN of the recipe used to create the solution.

datasetGroupArn -> (string)

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

eventType -> (string)

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.

solutionConfig -> (structure)

Describes the configuration properties for the solution.

eventValueThreshold -> (string)

Only events with a value greater than or equal to this threshold are used for training a model.

hpoConfig -> (structure)

Describes the properties for hyperparameter optimization (HPO).

hpoObjective -> (structure)

The metric to optimize during HPO.

Note

Amazon Personalize doesn’t support configuring the hpoObjective at this time.

type -> (string)

The type of the metric. Valid values are Maximize and Minimize .

metricName -> (string)

The name of the metric.

metricRegex -> (string)

A regular expression for finding the metric in the training job logs.

hpoResourceConfig -> (structure)

Describes the resource configuration for HPO.

maxNumberOfTrainingJobs -> (string)

The maximum number of training jobs when you create a solution version. The maximum value for maxNumberOfTrainingJobs is 40 .

maxParallelTrainingJobs -> (string)

The maximum number of parallel training jobs when you create a solution version. The maximum value for maxParallelTrainingJobs is 10 .

algorithmHyperParameterRanges -> (structure)

The hyperparameters and their allowable ranges.

integerHyperParameterRanges -> (list)

The integer-valued hyperparameters and their ranges.

(structure)

(structure)

Provides the name and range of a categorical hyperparameter.

name -> (string)

The name of the hyperparameter.

values -> (list)

autoMLConfig -> (structure)

The AutoMLConfig object containing a list of recipes to search when AutoML is performed.

metricName -> (string)

The metric to optimize.

recipeList -> (list)

(string)

optimizationObjective -> (structure)

Describes the additional objective for the solution, such as maximizing streaming minutes or increasing revenue. For more information see Optimizing a solution .

itemAttribute -> (string)

The numerical metadata column in an Items dataset related to the optimization objective. For example, VIDEO_LENGTH (to maximize streaming minutes), or PRICE (to maximize revenue).

objectiveSensitivity -> (string)

Specifies how Amazon Personalize balances the importance of your optimization objective versus relevance.

autoMLResult -> (structure)

When performAutoML is true, specifies the best recipe found.

bestRecipeArn -> (string)

The Amazon Resource Name (ARN) of the best recipe.

status -> (string)
