/**
 * 
 * Measurements of how well the MLModel performed on known observations. One of the following metrics is
 * returned, based on the type of the MLModel:
 * 
 * 
 * 
 * 
 * BinaryAUC: The binary MLModel uses the Area Under the Curve (AUC) technique to measure performance.
 * 
 * 
 * 
 * 
 * RegressionRMSE: The 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: The multiclass MLModel uses the F1 score technique to measure performance.
 * 
 * 
 * 
 * 
 * For more information about performance metrics, please see the Amazon Machine Learning Developer Guide.
