describe-ml-models

Description

Returns a list of MLModel that match the search criteria in the request.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

describe-ml-models is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Results

--eq (string)

The equal to operator. The MLModel results will have FilterVariable values that exactly match the value specified with EQ .

--gt (string)

The greater than operator. The MLModel results will have FilterVariable values that are greater than the value specified with GT .

--lt (string)

The less than operator. The MLModel results will have FilterVariable values that are less than the value specified with LT .

--ge (string)

The greater than or equal to operator. The MLModel results will have FilterVariable values that are greater than or equal to the value specified with GE .

--le (string)

The less than or equal to operator. The MLModel results will have FilterVariable values that are less than or equal to the value specified with LE .

--ne (string)

The not equal to operator. The MLModel results will have FilterVariable values not equal to the value specified with NE .

--prefix (string)

A string that is found at the beginning of a variable, such as Name or Id .

For example, an MLModel could have the Name 2014-09-09-HolidayGiftMailer . To search for this MLModel , select Name for the FilterVariable and any of the following strings for the Prefix :

  • 2014-09

  • 2014-09-09

  • 2014-09-09-Holiday

--sort-order (string)

A two-value parameter that determines the sequence of the resulting list of MLModel .

  • asc - Arranges the list in ascending order (A-Z, 0-9).

  • dsc - Arranges the list in descending order (Z-A, 9-0).

Results are sorted by FilterVariable .

Possible values:

  • asc

  • dsc

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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

Results -> (list)

A list of MLModel that meet the search criteria.

(structure)

Represents the output of a GetMLModel operation.

The content consists of the detailed metadata and the current status of the MLModel .

MLModelId -> (string)

The ID assigned to the MLModel at creation.

TrainingDataSourceId -> (string)

The ID of the training DataSource . The CreateMLModel operation uses the TrainingDataSourceId .

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:

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.shuffleType - Whether Amazon ML shuffles the training data. Shuffling the 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 .

  • sgd.l1RegularizationAmount - The coefficient regularization L1 norm, which controls overfitting the data by penalizing large coefficients. This parameter tends to drive coefficients to zero, resulting in 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, which 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.
