LiveHouse-TS introduces an open‑world living benchmark for Time Series Foundation Models, evaluating them prequentially on real future data rather than static test windows. The benchmark captures continuous performance across seasonal changes, distribution shifts, and unexpected events, providing a more realistic assessment of model robustness. Experiments across 11 domains and 17 datasets show that model rankings can dramatically change under this live protocol.

arXiv:2602. 17634v2 Announce Type: replace-cross Abstract: Learning time series foundation models has been shown to be a promising approach for zero-shot time series forecasting across diverse time series domains.
By Xinghong Fu, Yanhong Li, Georgios Papaioannou, Yoon Kim
The paper argues that zero‑shot time‑series forecasting should be treated as an evidence‑access claim rather than merely a no‑parameter‑update condition. It introduces a source‑first taxonomy that distinguishes three evidence sources—frozen LLM prior reuse, parametric time‑series pretraining, and retrieval‑augmented external memory—from the architectures that implement them. The authors further outline four audit questions—task interface, forecast object and scoring, prediction‑time context, and resource budget—to make zero‑shot leaderboards transparent and comparable.
