New paper calls for scenario-grounded stress testing for time series forecasting models

A new paper published on arXiv argues that current benchmarks for time series forecasting (TSF) are insufficient for real-world deployment. The authors contend that existing stress tests, which often focus on Gaussian noise or adversarial perturbations, fail to capture the complex failure modes of deployed systems. These failures can stem from structured events that alter temporal dynamics, break dependencies, or propagate from faulty sensors. The paper advocates for scenario-grounded stress testing, which would involve evaluating models based on explicit failure operators and measurable difficulty levels, making the evaluation more interpretable and deployment-relevant.
