Inference Synthesis

This package contains the logic from the Inference Synthesis Section of the Allora litepaper, which combine current inferences, forecasts, previous losses and current regrets into current network losses and new latest regrets per worker or combination of workers (and topic).

Functions

func CalcForecastImpliedInferences added in v0.6.0 

func CalcForecastImpliedInferences(args CalcForecastImpliedInferencesArgs) (
	forecasterToForecastImpliedInference map[Forecaster]*emissionstypes.Inference,
	infererToRegretOut map[Inferer]*Regret,
	forecasterToRegretOut map[Forecaster]*Regret,
	err error,
)

Calculate the forecast-implied inferences I_ik given inferences, forecasts and network losses. Calculates R_ijk, w_ijk, and I_ik for each forecast k and forecast element (forecast of worker loss) j

Forecast without inference => weight in calculation of I_ik and I_i set to 0. Use latest available regret R_i-1,l Inference without forecast => only weight in calculation of I_ik set to 0 A value of 0 => no inference corresponded to any of the forecasts from a forecaster

func CalcNetworkLosses 

func CalcNetworkLosses(
