Structured Hyperedge Adaptation for Parameter-Efficient Fine-Tuning of Vision Transformers
Edwin Kwadwo Tenagyei, Lei Wang, Ugochukwu Ejike Akpudo +2
Parameter-efficient fine-tuning (PEFT) has become a practical solution for adapting large pretrained vision transformers (ViTs) to downstream tasks while updating only a small subs…
Video Understanding by Design: How Datasets Shape Video Models
Lei Wang, Syuan-Hao Li, Piotr Koniusz +1
Research in video understanding has advanced rapidly, driven by increasingly diverse datasets and more powerful model architectures. While existing surveys typically organize progr…
Test-Time Self-Adaptive Conditioning for Stable Audio-Driven Talking-Head Generation
Zhicheng Zhang, Lei Wang, Yu Zhang +1
Audio-driven talking-head generation has achieved remarkable progress with recent models such as AniTalker, FLOAT, and Sonic. Despite their success, most existing approaches rely o…
Trust-Aware Joint Feature-Prediction Discrepancy for Robust Domain Adaptation
Xi Ding, Lei Wang, Syuan-Hao Li +1
Domain adaptation aims to mitigate performance degradation caused by distribution shifts between a labeled source domain and an unlabeled or sparsely labeled target domain. Most ex…
Uncertainty-DTW for Sequences and Visual Tokens
Lei Wang, Syuan-Hao Li, Yongsheng Gao +1
Aligning structured data is a fundamental problem in computer vision and machine learning, underlying tasks such as time series analysis, human action recognition, and visual repre…
Subspace Kernel Learning on Tensor Sequences
Lei Wang, Xi Ding, Yongsheng Gao +1
Learning from structured multi-way data, represented as higher-order tensors, requires capturing complex interactions across tensor modes while remaining computationally efficient.…
