TabPFN-TS 在建模协变量关系方面优于 Chronos-2

作者 PulseAugur 编辑部 · [1 个来源] · 2026-05-12 14:38

一项新的研究论文调查了两个主要的时序基础模型 Chronos-2 和 TabPFN-TS 集成协变量信息的效果。研究发现，TabPFN-TS 在捕捉协变量与目标变量之间简单关系方面更有效，尤其是在较短的预测范围内。这表明 Chronos-2 在基准测试中的强劲整体表现可能并不直接表明其在处理协变量依赖性方面更优。 AI

影响这项研究突出了高级时序模型处理协变量数据的潜在差异，这可能会影响预测任务的模型选择。

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…
