MLModel

public struct MLModel : AWSShape

Undocumented

  • Declaration

    Swift

    public static var _members: [AWSShapeMember]

  • The algorithm used to train the MLModel. The following algorithm is supported: SGD – Stochastic gradient descent. The goal of SGD is to minimize the gradient of the loss function.

    Declaration

    Swift

    public let inputDataLocationS3: String?

  • The time of the most recent edit to the MLModel. The time is expressed in epoch time.

    Declaration

    Swift

    public let lastUpdatedAt: TimeStamp?

  • A description of the most recent details about accessing the MLModel.

    Declaration

    Swift

    public let message: String?

  • The ID assigned to the MLModel at creation.

    Declaration

    Swift

    public let mLModelId: String?

  • Identifies the MLModel category. The following are the available types: REGRESSION - Produces a numeric result. For example, “What price should a house be listed at?” BINARY - Produces one of two possible results. For example, “Is this a child-friendly web site?”. MULTICLASS - Produces one of several possible results. For example, “Is this a HIGH-, LOW-, or MEDIUM-risk trade?”.

    Declaration

    Swift

    public let mLModelType: MLModelType?

  • A user-supplied name or description of the MLModel.

    Declaration

    Swift

    public let name: String?

  • Undocumented

    Declaration

    Swift

    public let scoreThreshold: Float?

  • The time of the most recent edit to the ScoreThreshold. The time is expressed in epoch time.

    Declaration

    Swift

    public let scoreThresholdLastUpdatedAt: TimeStamp?

  • Undocumented

    Declaration

    Swift

    public let sizeInBytes: Int64?

  • Undocumented

    Declaration

    Swift

    public let startedAt: TimeStamp?

  • The current status of an MLModel. This element can have one of the following values: PENDING - Amazon Machine Learning (Amazon ML) submitted a request to create an MLModel. INPROGRESS - The creation process is underway. FAILED - The request to create an MLModel didn’t run to completion. The model isn’t usable. COMPLETED - The creation process completed successfully. DELETED - The MLModel is marked as deleted. It isn’t usable.

    Declaration

    Swift

    public let status: EntityStatus?

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

    Declaration

    Swift

    public let trainingDataSourceId: 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. 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.
