NAME

Paws::MachineLearning::CreateMLModel - Arguments for method CreateMLModel on Paws::MachineLearning

DESCRIPTION

This class represents the parameters used for calling the method CreateMLModel on the Amazon Machine Learning service. Use the attributes of this class as arguments to method CreateMLModel.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to CreateMLModel.

SYNOPSIS

    my $machinelearning = Paws->service('MachineLearning');
    my $CreateMLModelOutput = $machinelearning->CreateMLModel(
      MLModelId            => 'MyEntityId',
      MLModelType          => 'REGRESSION',
      TrainingDataSourceId => 'MyEntityId',
      MLModelName          => 'MyEntityName',                         # OPTIONAL
      Parameters           => { 'MyStringType' => 'MyStringType', },  # OPTIONAL
      Recipe               => 'MyRecipe',                             # OPTIONAL
      RecipeUri            => 'MyS3Url',                              # OPTIONAL
    );

    # Results:
    my $MLModelId = $CreateMLModelOutput->MLModelId;

    # Returns a L<Paws::MachineLearning::CreateMLModelOutput> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/machinelearning/CreateMLModel

ATTRIBUTES

REQUIRED MLModelId => Str

A user-supplied ID that uniquely identifies the MLModel.

MLModelName => Str

A user-supplied name or description of the MLModel.

REQUIRED MLModelType => Str

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 (https://docs.aws.amazon.com/machine-learning/latest/dg).

Valid values are: "REGRESSION", "BINARY", "MULTICLASS"

Parameters => Paws::MachineLearning::TrainingParameters

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.

Recipe => Str

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.

RecipeUri => Str

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.

REQUIRED TrainingDataSourceId => Str

The DataSource that points to the training data.
