arXiv:2606.06285v1 Announce Type: new Abstract: Time series foundation models (TS-FMs) aim to learn generalizable temporal representations that can be adapted to a wide range of downstream tasks. In real-world multimodal settings, time series are frequently affected by temporal misalignment and partial modality missingness, where different modalities are observed at heterogeneous time scales or are partially absent. Existing approaches typically rely on naive imputation or masking strategies, which fail to account for cross-modal dependencies and often lead to misaligned or degraded representa
The proliferation of multimodal data and the growing ambition for generalizable AI models necessitate more robust methods for handling data imperfections inherent in real-world time series. This research addresses a critical technical challenge for advanced temporal AI systems.
Improved handling of multimodal, misaligned, and incomplete time series data is fundamental for advancing foundation models, particularly in applications requiring complex real-world sensor fusion and predictive analytics. This enhances the utility and reliability of AI in critical domains.
The development of TRACE introduces a new approach to conditional estimation in multimodal time series foundation models, potentially leading to more accurate and resilient AI systems that can operate effectively with imperfect data. This could accelerate the development of practical AI agents.
