TabPFN-TS outperforms Chronos-2 in modeling covariate relationships

By PulseAugur Editorial · [1 sources] ·

A new research paper investigates how well two prominent time series foundation models, Chronos-2 and TabPFN-TS, integrate covariate information. The study found that TabPFN-TS is more effective at capturing simple relationships between covariates and the target variable, particularly for shorter prediction horizons. This suggests that Chronos-2's strong overall performance on benchmarks may not directly indicate superior handling of covariate dependencies. AI

IMPACT This research highlights potential differences in how advanced time series models handle covariate data, which could influence model selection for forecasting tasks.

    Investigating simple target-covariate relationships for Chronos-2 and TabPFN-TS

    Time Series Foundation Models (TSFMs) have recently achieved state-of-the-art performance, often outperforming supervised models in zero-shot settings. Recent TSFM architectures, such as Chronos-2 and TabPFN-TS, aim to integrate covariates. In this paper, we design controlled exp…
