New Continuous Horizon strategy enhances multi-horizon forecasting accuracy

Researchers have introduced a novel Continuous Horizon (CH) strategy for multi-horizon forecasting, which generalizes existing discrete forecast methods. This new approach redefines forecasts as a continuous operator and the forecast horizon as a query variable, rather than a fixed index. The strategy is supported by theoretical foundations, including a Universal Operator Approximation Theorem and a continuous-horizon bias-variance decomposition, which demonstrate improved estimation variance over discrete methods. Empirical validation on the M-series benchmark across 16 large-scale datasets shows CH achieves competitive RMSE accuracy while enabling parallel inference, targeted horizon querying, and interpolation/extrapolation across unseen horizons.
