A new framework called NVExplain has been developed to improve the interpretability of time series forecasting models. This model-agnostic approach attributes forecast horizons to relevant historical lags by modeling forecasting as a latent trajectory and quantifying information evolution. NVExplain also generates structure-preserving perturbations and fits sparse local surrogate models to provide human-readable explanations. Evaluations show that the semantic-flow variant of NVExplain offers competitive faithfulness and superior computational efficiency compared to existing post-hoc methods, while also demonstrating robust explanations.
