FemWear: A Specialized Wearable Foundation Model for Women's Health
Yifan Wang, Chenzhong Li
General wearable foundation models are pretrained across broad sensor streams and populations, but are not designed around women's-health tasks. We introduce FemWear, a specialized…
Efficient Time Series Clustering from Multiscale Reservoir Dynamics with Granular-Ball Anchoring Graph Optimization
Yifan Wang, Lifeng Shen, Shuyin Xia +1
Time-series clustering remains challenging due to the inherent trade-off between clustering effectiveness and computational efficiency. Similarity-based methods often suffer from q…
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…
A Review of Brain-Computer Interface Technologies: Signal Acquisition Methods and Interaction Paradigms
Yifan Wang, Cheng Jiang, Chenzhong Li
Brain-Computer Interface (BCI) technology facilitates direct communication between the human brain and external devices, representing a substantial advancement in human-machine int…
