Forecasting Associations, Not Interventions: A Preregistered Causal Audit of Covariate-Aware Time Series Foundation Models

arXiv cs.LG ↗ · 2026-10-27 Cached

A preregistered causal audit finds that covariate-aware time series foundation models (Chronos-2, TiRex-2, TabPFN-TS, TimesFM-2.5) forecast associations rather than intervention effects, with a derived confounding gap that can be reduced up to 83% via brief interventional post-training with LoRA adapters.

Rethinking Time Series Tokenization from a Frequency Perspective

arXiv cs.LG ↗ · 2026-10-22 Cached

The paper identifies that existing time series tokenization strategies (patch and phase tokenization) introduce spectral distortions such as spectral leakage and aliasing, and proposes TimeFT, a parameter-free, nearly distortion-free frequency-based tokenizer that serves as a drop-in replacement and improves performance across forecasting, classification, and anomaly detection tasks.
