Class PerformanceMetrics

java.lang.Object

software.amazon.awssdk.services.machinelearning.model.PerformanceMetrics

All Implemented Interfaces:

StructuredPojo, ToCopyableBuilder<PerformanceMetrics.Builder,PerformanceMetrics>

@Generated("software.amazon.awssdk:codegen")
public class PerformanceMetrics
extends Object
implements StructuredPojo, ToCopyableBuilder<PerformanceMetrics.Builder,PerformanceMetrics>

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.
