Explainable Time Series Forecasting

Overview

Explainable time series forecasting studies how to show which past observations, variables, contexts, or learned dynamics shape predictions across future horizons. Approaches include post-hoc methods such as SHAP and counterfactuals, interpretable decompositions and symbolic equations, causal or concept-based models, and language-model reasoning. Methods are tested on settings such as energy demand, health, traffic, and industrial forecasting, where temporal dependence, multiple variables, uncertainty, and changing regimes matter. A central challenge is ensuring explanations are faithful and stable—not merely plausible—while preserving forecast accuracy, especially when different horizons rely on different evidence.

Surrogate Modeling for Explainable Predictive Time Series Corrections

We introduce a local surrogate approach for explainable time-series forecasting. An initially non-interpretable predictive model to improve the forecast of a classical time-series 'base model' is used. 'Explainability' of the correction is provided by fitting the base model again to the data from which the error prediction is removed (subtracted), yielding a difference in the model parameters which can be interpreted. We provide illustrative examples to demonstrate the potential of the method to discover and explain underlying patterns in the data.
