A user-supplied name or description of the MLModel.

Returns:

  • (String)

    A user-supplied name or description of the MLModel.

#recipeString

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.

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.

Returns:

  • (Float)

    The scoring threshold is used in binary classification MLModel<?oxy_insert_start author=\"laurama\" timestamp=\"20160329T114851-0700\"> <?oxy_insert_end>models.

Returns:

  • (Time)

    The epoch time when Amazon Machine Learning marked the MLModel as INPROGRESS.

#statusString

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

  • 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.

  • (String)

    The current status of the MLModel.

#training_data_source_idString

The ID of the training DataSource.

Returns:

  • (String)

    The ID of the training DataSource.

#training_parametersHash<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 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.

Returns:

  • (Hash<String,String>)

    A list of the training parameters in the MLModel.
