  - performanceMetrics
```
public 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.
