QiYao-I: A Manifold Based Foundation Model for Irregular Multivariate Time Series Forecasting

Linfeng Wang, Ruitong Zhang, Kai Zhao وآخرون · 2026

Irregular multivariate time series forecasting is a challenging yet important problem in real-world applications, where observations are often irregularly sampled and asynchronously recorded across variables. Existing time series foundation models are mostly built on regularly sampled sequences, making them difficult t …

QiYao-M: Multimodal Time Series Foundation Model with Role-Aware Modeling of Endogenous and Exogenous Modalities

Hanyin Cheng, Linfeng Wang, Zhengbo Qu وآخرون · 2026

Existing multimodal time series foundation models (TSFMs) typically model heterogeneous modalities through largely shared mechanisms, overlooking the distinct forecasting roles of endogenous and exogenous modalities. In this work, we propose QiYao-M, a role-aware multimodal TSFM that models the two types of modalities …
