Class PerformanceMetrics

java.lang.Object
com.amazonaws.services.machinelearning.model.PerformanceMetrics
All Implemented Interfaces:
Serializable, Cloneable
public class PerformanceMetrics extends Object implements Serializable, Cloneable

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.
