Overview

An API client for MachineLearning. To construct a client, you need to configure a ‘:region` and `:credentials`.

client = Aws::MachineLearning::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • ‘Aws::Credentials` - Used for configuring static, non-refreshing credentials.

    • ‘Aws::SharedCredentials` - Used for loading static credentials from a shared file, such as `~/.aws/config`.

    • ‘Aws::AssumeRoleCredentials` - Used when you need to assume a role.

    • ‘Aws::AssumeRoleWebIdentityCredentials` - Used when you need to assume a role after providing credentials via the web.

    • ‘Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an access token generated from `aws login`.

    • ‘Aws::ProcessCredentials` - Used for loading credentials from a process that outputs to stdout.

    • ‘Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • ‘Aws::ECSCredentials` - Used for loading credentials from instances running in ECS.

    • ‘Aws::CognitoIdentityCredentials` - Used for loading credentials from the Cognito Identity service.

    When ‘:credentials` are not configured directly, the following locations will be searched for credentials:

    • ‘Aws.config`

    • The ‘:access_key_id`, `:secret_access_key`, and `:session_token` options.

    • ENV, ENV

    • ‘~/.aws/credentials`

    • ‘~/.aws/config`

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV to true.

  • :region (required, String) —

    The AWS region to connect to. The configured ‘:region` is used to determine the service `:endpoint`. When not passed, a default `:region` is searched for in the following locations:

  • :endpoint_provider (Aws::MachineLearning::EndpointProvider) —

    The endpoint provider used to resolve endpoints. Any object that responds to ‘#resolve_endpoint(parameters)` where `parameters` is a Struct similar to `Aws::MachineLearning::EndpointParameters`

  • :http_continue_timeout (Float) — default: 1 —

    The number of seconds to wait for a 100-continue response before sending the request body. This option has no effect unless the request has “Expect” header set to “100-continue”. Defaults to ‘nil` which disables this behaviour. This value can safely be set per request on the session.

  • :http_idle_timeout (Float) — default: 5 —

    The number of seconds a connection is allowed to sit idle before it is considered stale. Stale connections are closed and removed from the pool before making a request.

#create_batch_prediction(params = {}) ⇒ Types::CreateBatchPredictionOutput

Generates predictions for a group of observations. The observations to process exist in one or more data files referenced by a ‘DataSource`. This operation creates a new `BatchPrediction`, and uses an `MLModel` and the data files referenced by the `DataSource` as information sources.

‘CreateBatchPrediction` is an asynchronous operation. In response to `CreateBatchPrediction`, Amazon Machine Learning (Amazon ML) immediately returns and sets the `BatchPrediction` status to `PENDING`. After the `BatchPrediction` completes, Amazon ML sets the status to `COMPLETED`.

You can poll for status updates by using the GetBatchPrediction operation and checking the ‘Status` parameter of the result. After the `COMPLETED` status appears, the results are available in the location specified by the `OutputUri` parameter.

Examples:

  output_uri: "S3Url", # required
})

Response structure


resp.batch_prediction_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :batch_prediction_id (required, String) —

    A user-supplied ID that uniquely identifies the ‘BatchPrediction`.

  • :batch_prediction_name (String) —

    A user-supplied name or description of the ‘BatchPrediction`. `BatchPredictionName` can only use the UTF-8 character set.

  • :ml_model_id (required, String) —

    The ID of the ‘MLModel` that will generate predictions for the group of observations.

  • :batch_prediction_data_source_id (required, String) —

    The ID of the ‘DataSource` that points to the group of observations to predict.

  • :output_uri (required, String) —

    The location of an Amazon Simple Storage Service (Amazon S3) bucket or directory to store the batch prediction results. The following substrings are not allowed in the ‘s3 key` portion of the `outputURI` field: ’:‘, ’//‘, ’/./‘, ’/../‘.

    Amazon ML needs permissions to store and retrieve the logs on your behalf. For information about how to set permissions, see the [Amazon Machine Learning Developer Guide].

#create_data_source_from_rds(params = {}) ⇒ Types::CreateDataSourceFromRDSOutput

Creates a ‘DataSource` object from an [ Amazon Relational Database Service] (Amazon RDS). A `DataSource` references data that can be used to perform `CreateMLModel`, `CreateEvaluation`, or `CreateBatchPrediction` operations.

‘CreateDataSourceFromRDS` is an asynchronous operation. In response to `CreateDataSourceFromRDS`, Amazon Machine Learning (Amazon ML) immediately returns and sets the `DataSource` status to `PENDING`. After the `DataSource` is created and ready for use, Amazon ML sets the `Status` parameter to `COMPLETED`. `DataSource` in the `COMPLETED` or `PENDING` state can be used only to perform `>CreateMLModel`&gt;, `CreateEvaluation`, or `CreateBatchPrediction` operations.

If Amazon ML cannot accept the input source, it sets the ‘Status` parameter to `FAILED` and includes an error message in the `Message` attribute of the `GetDataSource` operation response.

#create_data_source_from_redshift(params = {}) ⇒ Types::CreateDataSourceFromRedshiftOutput

Creates a ‘DataSource` from a database hosted on an Amazon Redshift cluster. A `DataSource` references data that can be used to perform either `CreateMLModel`, `CreateEvaluation`, or `CreateBatchPrediction` operations.

‘CreateDataSourceFromRedshift` is an asynchronous operation. In response to `CreateDataSourceFromRedshift`, Amazon Machine Learning (Amazon ML) immediately returns and sets the `DataSource` status to `PENDING`. After the `DataSource` is created and ready for use, Amazon ML sets the `Status` parameter to `COMPLETED`. `DataSource` in `COMPLETED` or `PENDING` states can be used to perform only `CreateMLModel`, `CreateEvaluation`, or `CreateBatchPrediction` operations.

If Amazon ML can’t accept the input source, it sets the ‘Status` parameter to `FAILED` and includes an error message in the `Message` attribute of the `GetDataSource` operation response.

The observations should be contained in the database hosted on an Amazon Redshift cluster and should be specified by a ‘SelectSqlQuery` query. Amazon ML executes an `Unload` command in Amazon Redshift to transfer the result set of the `SelectSqlQuery` query to `S3StagingLocation`.

After the ‘DataSource` has been created, it’s ready for use in evaluations and batch predictions. If you plan to use the ‘DataSource` to train an `MLModel`, the `DataSource` also requires a recipe. A recipe describes how each input variable will be used in training an `MLModel`. Will the variable be included or excluded from training? Will the variable be manipulated; for example, will it be combined with another variable or will it be split apart into word combinations? The recipe provides answers to these questions.

You can’t change an existing datasource, but you can copy and modify the settings from an existing Amazon Redshift datasource to create a new datasource. To do so, call ‘GetDataSource` for an existing datasource and copy the values to a `CreateDataSource` call. Change the settings that you want to change and make sure that all required fields have the appropriate values.

#create_data_source_from_s3(params = {}) ⇒ Types::CreateDataSourceFromS3Output

Creates a ‘DataSource` object. A `DataSource` references data that can be used to perform `CreateMLModel`, `CreateEvaluation`, or `CreateBatchPrediction` operations.

‘CreateDataSourceFromS3` is an asynchronous operation. In response to `CreateDataSourceFromS3`, Amazon Machine Learning (Amazon ML) immediately returns and sets the `DataSource` status to `PENDING`. After the `DataSource` has been created and is ready for use, Amazon ML sets the `Status` parameter to `COMPLETED`. `DataSource` in the `COMPLETED` or `PENDING` state can be used to perform only `CreateMLModel`, `CreateEvaluation` or `CreateBatchPrediction` operations.

If Amazon ML can’t accept the input source, it sets the ‘Status` parameter to `FAILED` and includes an error message in the `Message` attribute of the `GetDataSource` operation response.

The observation data used in a ‘DataSource` should be ready to use; that is, it should have a consistent structure, and missing data values should be kept to a minimum. The observation data must reside in one or more .csv files in an Amazon Simple Storage Service (Amazon S3) location, along with a schema that describes the data items by name and type. The same schema must be used for all of the data files referenced by the `DataSource`.

After the ‘DataSource` has been created, it’s ready to use in evaluations and batch predictions. If you plan to use the ‘DataSource` to train an `MLModel`, the `DataSource` also needs a recipe. A recipe describes how each input variable will be used in training an `MLModel`. Will the variable be included or excluded from training? Will the variable be manipulated; for example, will it be combined with another variable or will it be split apart into word combinations? The recipe provides answers to these questions.

#create_evaluation(params = {}) ⇒ Types::CreateEvaluationOutput

Creates a new ‘Evaluation` of an `MLModel`. An `MLModel` is evaluated on a set of observations associated to a `DataSource`. Like a `DataSource` for an `MLModel`, the `DataSource` for an `Evaluation` contains values for the `Target Variable`. The `Evaluation` compares the predicted result for each observation to the actual outcome and provides a summary so that you know how effective the `MLModel` functions on the test data. Evaluation generates a relevant performance metric, such as BinaryAUC, RegressionRMSE or MulticlassAvgFScore based on the corresponding `MLModelType`: `BINARY`, `REGRESSION` or `MULTICLASS`.

‘CreateEvaluation` is an asynchronous operation. In response to `CreateEvaluation`, Amazon Machine Learning (Amazon ML) immediately returns and sets the evaluation status to `PENDING`. After the `Evaluation` is created and ready for use, Amazon ML sets the status to `COMPLETED`.

You can use the ‘GetEvaluation` operation to check progress of the evaluation during the creation operation.

Examples:

resp = client.create_evaluation({
  evaluation_id: "EntityId", # required
  evaluation_name: "EntityName",

})

Response structure


resp.evaluation_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

Options Hash (params):

  • :evaluation_id (required, String) —

    A user-supplied ID that uniquely identifies the ‘Evaluation`.

  • :evaluation_name (String) —

    A user-supplied name or description of the ‘Evaluation`.

  • :ml_model_id (required, String) —

    The ID of the ‘MLModel` to evaluate.

    The schema used in creating the ‘MLModel` must match the schema of the `DataSource` used in the `Evaluation`.

  • :evaluation_data_source_id (required, String) —

    The ID of the ‘DataSource` for the evaluation. The schema of the `DataSource` must match the schema used to create the `MLModel`.

#create_ml_model(params = {}) ⇒ Types::CreateMLModelOutput

Creates a new ‘MLModel` using the `DataSource` and the recipe as information sources.

An ‘MLModel` is nearly immutable. Users can update only the `MLModelName` and the `ScoreThreshold` in an `MLModel` without creating a new `MLModel`.

‘CreateMLModel` is an asynchronous operation. In response to `CreateMLModel`, Amazon Machine Learning (Amazon ML) immediately returns and sets the `MLModel` status to `PENDING`. After the `MLModel` has been created and ready is for use, Amazon ML sets the status to `COMPLETED`.

You can use the ‘GetMLModel` operation to check the progress of the `MLModel` during the creation operation.

‘CreateMLModel` requires a `DataSource` with computed statistics, which can be created by setting `ComputeStatistics` to `true` in `CreateDataSourceFromRDS`, `CreateDataSourceFromS3`, or `CreateDataSourceFromRedshift` operations.

Examples:

Request syntax with placeholder values


resp = client.create_ml_model({
  ml_model_id: "EntityId", # required
  ml_model_name: "EntityName",
  ml_model_type: "REGRESSION", # required, accepts REGRESSION, BINARY, MULTICLASS
  parameters: {

})

Response structure


resp.ml_model_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :ml_model_id (required, String) —

    A user-supplied ID that uniquely identifies the ‘MLModel`.

  • :ml_model_name (String) —

    A user-supplied name or description of the ‘MLModel`.

  • :ml_model_type (required, String) —

    The category of supervised learning that this ‘MLModel` will address. Choose from the following types:

    • Choose ‘REGRESSION` if the `MLModel` will be used to predict a numeric value.

    • Choose ‘BINARY` if the `MLModel` result has two possible values.

    • Choose ‘MULTICLASS` if the `MLModel` result has a limited number of values.

    For more information, see the [Amazon Machine Learning Developer Guide].

    [1]: docs.aws.amazon.com/machine-learning/latest/dg

  • :parameters (Hash<String,String>) —

    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 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`. 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.

  • :training_data_source_id (required, String) —

    The ‘DataSource` that points to the training data.

  • :recipe (String) —

    The data recipe for creating the ‘MLModel`. You must specify either the recipe or its URI. If you don’t specify a recipe or its URI, Amazon ML creates a default.

  • :recipe_uri (String) —

    The Amazon Simple Storage Service (Amazon S3) location and file name that contains the ‘MLModel` recipe. You must specify either the recipe or its URI. If you don’t specify a recipe or its URI, Amazon ML creates a default.

#update_evaluation(params = {}) ⇒ Types::UpdateEvaluationOutput

Updates the ‘EvaluationName` of an `Evaluation`.

You can use the ‘GetEvaluation` operation to view the contents of the updated data element.

Examples:

Request syntax with placeholder values


resp = client.update_evaluation({
  evaluation_id: "EntityId", # required
  evaluation_name: "EntityName", # required
})

Response structure


resp.evaluation_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :evaluation_id (required, String) —

    The ID assigned to the ‘Evaluation` during creation.

  • :evaluation_name (required, String) —

    A new user-supplied name or description of the ‘Evaluation` that will replace the current content.

Returns:

#update_ml_model(params = {}) ⇒ Types::UpdateMLModelOutput

Updates the ‘MLModelName` and the `ScoreThreshold` of an `MLModel`.

You can use the ‘GetMLModel` operation to view the contents of the updated data element.

Examples:

Request syntax with placeholder values


resp = client.update_ml_model({
  ml_model_id: "EntityId", # required
  ml_model_name: "EntityName",
  score_threshold: 1.0,
})

Response structure


resp.ml_model_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :ml_model_id (required, String) —

    The ID assigned to the ‘MLModel` during creation.

  • :ml_model_name (String) —

    A user-supplied name or description of the ‘MLModel`.

  • :score_threshold (Float) —

    The ‘ScoreThreshold` used in binary classification `MLModel` that marks the boundary between a positive prediction and a negative prediction.

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

Returns:

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean

Polls an API operation until a resource enters a desired state.

## Basic Usage

A waiter will call an API operation until:

  • It is successful

  • It enters a terminal state

  • It makes the maximum number of attempts

In between attempts, the waiter will sleep.

# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.

# poll for ~25 seconds
client.wait_until(waiter_name, params, {
  max_attempts: 5,
  delay: 5,
})

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw ‘:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(waiter_name, params, {

  # disable max attempts
  max_attempts: nil,

  # poll for 1 hour, instead of a number of attempts
  before_wait: -> (attempts, response) do
    throw :failure if Time.now - started_at > 3600
  end
})

## Handling Errors

When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

## Valid Waiters

The following table lists the valid waiter names, the operations they call, and the default ‘:delay` and `:max_attempts` values.

| waiter_name | params | :delay | :max_attempts | | ————————– | ———————————– | ——– | ————- | | batch_prediction_available | #describe_batch_predictions | 30 | 60 | | data_source_available | #describe_data_sources | 30 | 60 | | evaluation_available | #describe_evaluations | 30 | 60 | | ml_model_available | #describe_ml_models | 30 | 60 |

Parameters:

  • waiter_name (Symbol)
  • params (Hash) (defaults to: {}) —

    ({})

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :max_attempts (Integer)
  • :delay (Integer)
  • :before_attempt (Proc)
  • :before_wait (Proc)

Yields:

  • (w.waiter)

Returns:

  • (Boolean) —

    Returns ‘true` if the waiter was successful.

Raises:

  • (Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError) —

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError) —

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError) —

    Raised when you request to wait for an unknown state.
