Curriculum-Aware Interpolate-then-Refine: Learned Physiological Time-Series Imputation under Realistic Missingness

Yu-Chao Huang, Haochen Zhang, Nicholas Konz +1

Imputing physiological time series (arterial blood pressure, blood glucose, etc.) is essential for addressing the missingness that pervades clinical data. Yet modern imputation met…

GALA: Generation-Aware Cross-Modal Alignment for Text-to-Time-Series Synthesis

Haochen Zhang, Gengwei Zhang, Laura Yao +2

Synthesizing time series from natural language is emerging as the most expressive form of controllable time series generation. However, existing text-conditioned generators either…

Represent, Then Generate: Multimodal-Conditioned Time-Series Generation under Irregular Missingness

Haochen Zhang, Jiaheng Guo, Yu-Chao Huang +2

Continuous physiological time series underpin modern clinical monitoring, yet many of the most informative signals are invasive, expensive, or simply unavailable for a given patien…

PAMF: Prior-Aware Multimodal Fusion for Incomplete Time Series Data

Ziwen Kan, Wugeng Zheng, Tianlong Chen +1

In healthcare, multimodal time series tasks often operate on incomplete observations in practice, for example when ECG segments are lost because electrodes detach or an entire resp…

TRACE: A Temporal Conditional Estimation for Multimodal Time Series Foundation Models

Ziwen Kan, Yishuo Chen, Kecheng Li +7

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 setting…

ConceptMoE: Concept-Guided Multimodal Mixture of Experts for Interpretable Computational Pathology

Xuan Wang, Zhongling Xu, Gopi Kannedhara +13

Healthcare models are transitioning from unimodal prediction toward multimodal reasoning over heterogeneous diagnostic inputs. In computational pathology, for complex tumor subtype…
