Dec 05, 2025 đź“„ My work with Jingwen Zhang, PhD (First Author), Addressing Cohort Variability with Adaptive Fusion of Wearable and Clinical Data: A Case Study in Predicting Pancreatic Surgery Outcomes, has been accepted in ACM Transactions on Computing for Healthcare (HEALTH).
Paper Summary
  • We identify substantial cohort variability, exemplified by pre- vs. post-COVID surgical populations, and show that wearable and clinical features provide differing predictive value across patients, undermining fixed-weight multimodal models.
  • To address this, we introduce AdaMoE, an adaptive Mixture-of-Experts framework with diversity regularization that dynamically fuses wearable and clinical data, achieving more robust and accurate post-surgical outcome prediction than existing fusion methods.

Sep 18, 2025 đź“„ CHEF-VL: Detecting Cognitive Sequencing Errors in Cooking with Vision-Language Models, accepted to Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies and to be presented at UbiComp / ISWC 2026 in Oct. 2026 in Shanghai.
Paper Summary
  • Two-Year Real-World Data Collection:
    Developed a Smart Kitchen environment and collected a large, richly annotated dataset from over 100 participants performing a standardized cooking task, enabling research grounded in authentic human behavior.
  • A New AI Framework for Cognitive Support:
    Introduced CHEF-VL, a dual–Vision-Language Model system that integrates action recognition, environmental state detection, and action–state refinement to accurately detect sequencing errors in real time.
