## Methods detail

# `public static `Guzzle\Service\Resource\Model``
`factory( array $config = array() )`

Executes the UpdateMLModel operation.

Updates the MLModelName and the ScoreThreshold of an MLModel .

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

#### Parameters

$config
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - MLModelId => (string)

    The ID assigned to the MLModel during creation.

  - MLModelName => (string)

    A user-supplied name or description of the MLModel.

  - ScoreThreshold => (int)

    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

``Guzzle\Service\Resource\Model``
Returns a response Model object

- MLModelId => (string)

  The ID assigned to the MLModel during creation. This value should be identical to the value of the MLModelID in the request.

#### Overrides

`Guzzle\Service\Client::factory`
# `public `Guzzle\Service\Resource\Model``
`createBatchPrediction( array $args = array() )`

Executes the CreateBatchPrediction operation.

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

- Basic formatting example

      $result = $client->createBatchPrediction(array(
          // BatchPredictionId is required
          'BatchPredictionId' => 'string',

# `public `Guzzle\Service\Resource\Model``
`createMLModel( array $args = array() )`

Executes the CreateMLModel operation.

Creates a new MLModel using the data files and the recipe as information sources.

An MLModel is nearly immutable. Users can only update 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 is created and ready for use, Amazon ML sets the status to COMPLETED .

You can use the GetMLModel operation to check 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

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

  - Parameters => (associative-array<string>)

    Associative array of <StringType> keys mapping to (string) values. Each array key should be changed to an appropriate <StringType>.

    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.l1RegularizationAmount - Coefficient regularization L1 norm. It controls overfitting the data by penalizing large coefficients. This 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 not to use L1 normalization. The parameter cannot be used when L2 is specified. Use this parameter sparingly.

    - sgd.l2RegularizationAmount - 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 valuseis a double that ranges from 0 to MAX_DOUBLE. The default is not to use L2 normalization. This cannot be used when L1 is specified. Use this parameter sparingly.

    - sgd.maxPasses - 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.maxMLModelSizeInBytes - 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.

    - <StringType> => (string)

      String type.

  - TrainingDataSourceId => (string)

    The DataSource that points to the training data.

  - Recipe => (string)

    The data recipe for creating 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.

  - RecipeUri => (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.

- TrainingParameters => (associative-array<string>)

  Associative array of <string> keys mapping to (string) values. Each array key should be changed to an appropriate <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.l1RegularizationAmount - 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, specify a small value, such as 1.0E-04 or 1.0E-08.

    The value is a double that ranges from 0 to MAX_DOUBLE. The default is not to use L1 normalization. The parameter cannot be used when L2 is specified. Use this parameter sparingly.

  - sgd.l2RegularizationAmount - 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, specify a small value, such as 1.0E-04 or 1.0E-08.

    The value is a double that ranges from 0 to MAX_DOUBLE. The default is not to use L2 normalization. This parameter cannot be used when L1 is specified. Use this parameter sparingly.

  - 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.maxMLModelSizeInBytes - The maximum allowed size of the model. Depending on the input data, the model size might affect performance.

    The value is an integer that ranges from 100000 to 2147483648. The default value is 33554432.

  - <string> => (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 listing price should a house have?"
  - BINARY -- Produces one of two possible results. For example, "Is this an e-commerce website?"
  - MULTICLASS -- Produces more than two possible results. For example, "Is this a HIGH, LOW or MEDIUM risk trade?"
- ScoreThreshold => (int)

  The scoring threshold is used in binary classification MLModels, and 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 => (string)

  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)
