get-ml-model

Description

Returns an MLModel that includes detailed metadata, data source information, and the current status of the MLModel .

GetMLModel provides results in normal or verbose format.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-ml-model
--ml-model-id <value>
[--verbose | --no-verbose]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--ml-model-id (string)

The ID assigned to the MLModel at creation.

--verbose | --no-verbose (boolean)

Specifies whether the GetMLModel operation should return Recipe .

If true, Recipe is returned.

If false, Recipe is not returned.

--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.

See ‘aws help’ for descriptions of global parameters.

Output

MLModelId -> (string)

The MLModel ID, which is same as the MLModelId in the request.

TrainingDataSourceId -> (string)

The ID of the training DataSource .

CreatedByIamUser -> (string)

The AWS user account from which the MLModel was created. The account type can be either an AWS root account or an AWS Identity and Access Management (IAM) user account.

CreatedAt -> (timestamp)

The time that the MLModel was created. The time is expressed in epoch time.

LastUpdatedAt -> (timestamp)

The time of the most recent edit to the MLModel . The time is expressed in epoch time.

Name -> (string)

A user-supplied name or description of the MLModel .

Status -> (string)

The current status of the MLModel . This element can have one of the following values:

• PENDING - Amazon Machine Learning (Amazon ML) submitted a request to describe a MLModel .

• INPROGRESS - The request is processing.

• FAILED - The request did not run to completion. The ML model isn’t usable.

• COMPLETED - The request completed successfully.

• DELETED - The MLModel is marked as deleted. It isn’t usable.

SizeInBytes -> (long)

Long integer type that is a 64-bit signed number.

EndpointInfo -> (structure)

The current endpoint of the MLModel

PeakRequestsPerSecond -> (integer)

The maximum processing rate for the real-time endpoint for MLModel , measured in incoming requests per second.

CreatedAt -> (timestamp)

The time that the request to create the real-time endpoint for the MLModel was received. The time is expressed in epoch time.

EndpointUrl -> (string)

The URI that specifies where to send real-time prediction requests for the MLModel .

Note: The application must wait until the real-time endpoint is ready before using this URI.

EndpointStatus -> (string)

The current status of the real-time endpoint for the MLModel . This element can have one of the following values:

• NONE - Endpoint does not exist or was previously deleted.

• READY - Endpoint is ready to be used for real-time predictions.

• UPDATING - Updating/creating the endpoint.

TrainingParameters -> (map)

A list of the training parameters in the MLModel . The list is implemented as a map of key-value pairs.

The following is the current set of training parameters:

• sgd.maxMLModelSizeInBytes - The maximum allowed size of the model. Depending on the input data, the size of the model might affect its performance. The value is an integer that ranges from 100000 to 2147483648 . The default value is 33554432 .

• sgd.maxPasses - The number of times that the training process traverses the observations to build the MLModel . The value is an integer that ranges from 1 to 10000 . The default value is 10 .

• sgd.shuffleType - Whether Amazon ML shuffles the training data. Shuffling data improves a model’s ability to find the optimal solution for a variety of data types. The valid values are auto and none . The default value is none . We strongly recommend that you shuffle your data.

• sgd.l1RegularizationAmount - The coefficient regularization L1 norm. It controls overfitting the data by penalizing large coefficients. This tends to drive coefficients to zero, resulting in a sparse feature set. If you use this parameter, start by specifying a small value, such as 1.0E-08 . The value is a double that ranges from 0 to MAX_DOUBLE . The default is to not use L1 normalization. This parameter can’t be used when L2 is specified. Use this parameter sparingly.

• sgd.l2RegularizationAmount - The coefficient regularization L2 norm. It controls overfitting the data by penalizing large coefficients. This tends to drive coefficients to small, nonzero values. If you use this parameter, start by specifying a small value, such as 1.0E-08 . The value is a double that ranges from 0 to MAX_DOUBLE . The default is to not use L2 normalization. This parameter can’t be used when L1 is specified. Use this parameter sparingly.

key -> (string)

String type.

value -> (string)

String type.

InputDataLocationS3 -> (string)

The location of the data file or directory in Amazon Simple Storage Service (Amazon S3).

MLModelType -> (string)

Identifies the MLModel category. The following are the available types:

• REGRESSION – Produces a numeric result. For example, “What price should a house be listed at?”

• BINARY – Produces one of two possible results. For example, “Is this an e-commerce website?”

• MULTICLASS – Produces one of several possible results. For example, “Is this a HIGH, LOW or MEDIUM risk trade?”

ScoreThreshold -> (float)

The scoring threshold is used in binary classification MLModel models. It marks the boundary between a positive prediction and a negative prediction.

Output values greater than or equal to the threshold receive a positive result from the MLModel, such as true . Output values less than the threshold receive a negative response from the MLModel, such as false .

ScoreThresholdLastUpdatedAt -> (timestamp)

The time of the most recent edit to the ScoreThreshold . The time is expressed in epoch time.

LogUri -> (string)

A link to the file that contains logs of the CreateMLModel operation.

Message -> (string)

A description of the most recent details about accessing the MLModel .

ComputeTime -> (long)

The approximate CPU time in milliseconds that Amazon Machine Learning spent processing the MLModel , normalized and scaled on computation resources. ComputeTime is only available if the MLModel is in the COMPLETED state.

FinishedAt -> (timestamp)

The epoch time when Amazon Machine Learning marked the MLModel as COMPLETED or FAILED . FinishedAt is only available when the MLModel is in the COMPLETED or FAILED state.

StartedAt -> (timestamp)

The epoch time when Amazon Machine Learning marked the MLModel as INPROGRESS . StartedAt isn’t available if the MLModel is in the PENDING state.

Recipe -> (string)

The recipe to use when training the MLModel . The Recipe provides detailed information about the observation data to use during training, and manipulations to perform on the observation data during training.

Note: This parameter is provided as part of the verbose format.

Schema -> (string)

The schema used by all of the data files referenced by the DataSource .

Note: This parameter is provided as part of the verbose format.
