OPDSearch+: On-Policy Distillation with RL Refinement for Search-Augmented Reasoning
Qinglin Ye, Zhiyuan Gu, Jingjie Xia +6
Search-augmented reasoning remains difficult for small language models. On-policy distillation (OPD) from trained teachers offers a promising direction, but suffers from two issues…
Semi-Supervised Gaze Estimation via Disentangled Subspace Contrastive Learning
Qida Tan, Hongyu Yang, Wenchao Du
Appearance-based gaze estimation always suffers from poor generalization due to limited annotated samples and insufficient dataset diversity. Leading approaches adopt weakly superv…
Progressively Texture-Aware Diffusion for Contrast-Enhanced Sparse-View CT
Tianqi Wang, Wenchao Du, Hongyu Yang
Diffusion-based sparse-view CT (SVCT) imaging has achieved remarkable advancements in recent years, thanks to its more stable generative capability. However, recovering reliable im…
Hybrid-Domain Adaptative Representation Learning for Gaze Estimation
Qida Tan, Hongyu Yang, Wenchao Du
Appearance-based gaze estimation, aiming to predict accurate 3D gaze direction from a single facial image, has made promising progress in recent years. However, most methods suffer…
Affective Behavior Analysis using Task-adaptive and AU-assisted Graph Network
Xiaodong Li, Wenchao Du, Hongyu Yang
In this paper, we present our solution and experiment result for the Multi-Task Learning Challenge of the 7th Affective Behavior Analysis in-the-wild(ABAW7) Competition. This chall…
