/AWS1/CL_FCS=>GETACCURACYMETRICS()¶
About GetAccuracyMetrics¶
Provides metrics on the accuracy of the models that were trained by the CreatePredictor operation. Use metrics to see how well the model performed and to decide whether to use the predictor to generate a forecast. For more information, see Predictor Metrics.
This operation generates metrics for each backtest window that was evaluated. The number
of backtest windows (NumberOfBacktestWindows) is specified using the EvaluationParameters object, which is optionally included in the
CreatePredictor request. If NumberOfBacktestWindows isn't
specified, the number defaults to one.
The parameters of the filling method determine which items contribute to the
metrics. If you want all items to contribute, specify zero. If you want only
those items that have complete data in the range being evaluated to contribute, specify
nan. For more information, see FeaturizationMethod.
Before you can get accuracy metrics, the Status of the predictor must be
ACTIVE, signifying that training has completed. To get the status, use the
DescribePredictor operation.
