openstef_beam.benchmarking.baselines.openstef4.create_openstef4_preset_backtest_forecaster(workflow_config: ForecastingWorkflowConfig | EnsembleForecastingWorkflowConfig, backtest_config: BacktestForecasterConfig | None = None, cache_dir: Path = Path('cache')) → ForecasterFactory[BenchmarkTarget][source]#

Create a factory that returns an OpenSTEF4BacktestForecaster for a benchmark target.

Parameters:

  • workflow_config (ForecastingWorkflowConfig | EnsembleForecastingWorkflowConfig) – The configured ForecastingWorkflowConfig that will be cloned and assigned to a target-specific workflow instance.

  • backtest_config (BacktestForecasterConfig | None) – Optional BacktestForecasterConfig to control training/prediction windows. If None, a sensible default is created.

  • cache_dir (Path) – Directory to store cached artifacts for created forecasters. A subdirectory will be created per benchmark run and target.

  • workflow_config

  • backtest_config

  • cache_dir

Returns:

A ForecasterFactory[BenchmarkTarget] partial which accepts a BenchmarkContext and a BenchmarkTarget and returns a configured OpenSTEF4BacktestForecaster.

Return type:

GenericAlias[BenchmarkTarget]
