FemWear: A Parameter-Efficient Wearable Foundation Model for Women's Health
Yifan Wang, Chenzhong Li
General-purpose wearable foundation models are pretrained on broad sensor streams and populations, but their representations are not organized around women's health. FemWear is a w…
Discrepancy-Aware Contrastive Adaptation in Medical Time Series Analysis
Yifan Wang, Hongfeng Ai, Ruiqi Li +5
In medical time series disease diagnosis, two key challenges are identified. First, the high annotation cost of medical data leads to overfitting in models trained on label-limited…
Optimizing Vision-Language Consistency via Cross-Layer Regional Attention Alignment
Yifan Wang, Hongfeng Ai, Quangao Liu +7
Vision Language Models (VLMs) face challenges in effectively coordinating diverse attention mechanisms for cross-modal embedding learning, leading to mismatched attention and subop…
