      • performanceMetrics

        public final PerformanceMetrics 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.
