Researchers have introduced Horizon-Resolved Attribution (HRA), a novel framework designed to improve the explainability of time series forecasting models. Unlike previous methods that provide a single importance vector, HRA generates distinct importance maps for each forecast step, acknowledging that different future predictions rely on different historical data points. This plug-in framework includes an estimator for extracting these maps, an evaluation protocol to validate the horizon axis, and a criterion to predict when resolving the horizon is beneficial. Experiments demonstrate that HRA enhances explanation accuracy across various forecasting models and datasets. AI
