Returns:

  • (String)

    The AWS user account that invoked the evaluation.

#evaluation_data_source_idString

The ID of the DataSource that is used to evaluate the MLModel.

Returns:

  • (String)

    The ID of the DataSource that is used to evaluate the MLModel.

#evaluation_idString

The ID that is assigned to the Evaluation at creation.

Returns:

  • (String)

    The ID that is assigned to the Evaluation at creation.

#finished_atTime

A timestamp represented in epoch time.

Returns:

#performance_metricsTypes::PerformanceMetrics

Measurements of how well the MLModel performed, using observations referenced by the DataSource. One of the following metrics is returned, based on the type of the MLModel:

  • BinaryAUC: A binary MLModel uses the Area Under the Curve (AUC) technique to measure performance.

  • RegressionRMSE: A regression MLModel uses the Root Mean Square Error (RMSE) technique to measure performance. RMSE measures the difference between predicted and actual values for a single variable.

  • MulticlassAvgFScore: A multiclass MLModel uses the F1 score technique to measure performance.

For more information about performance metrics, please see the Amazon Machine Learning Developer Guide.

Returns:

  • (Types::PerformanceMetrics)

    Measurements of how well the MLModel performed, using observations referenced by the DataSource.
