Researchers have developed MELO, a novel model-agnostic method for online prediction that hedges across different adaptation scales. MELO wraps base predictors with exponentially weighted least-squares adaptation experts and aggregates their forecasts using a parameter-free online aggregation rule. In evaluations on French electricity load forecasting during the COVID-19 lockdown, MELO significantly reduced RMSE compared to baseline methods and a reference model that used external policy covariates.
