Scene Experts: Specializing in 3D Gaussian Splatting with Adaptive Decomposition

Xiaowen Fu, Yang Zhang, Yuhan Tang, Huazhong Zhang, Tianxing Zhao, Yuhang Guo +2

AAAI 2026technical

Anchor-based 3D Gaussian Splatting (GS), exemplified by Scaffold-GS, achieves remarkable storage efficiency through a hybrid explicit-implicit representation. However, their reliance on a single, monolithic network to decode anchor features imposes a severe bottleneck on model capacity, often result

DiffHammer: Rethinking the Robustness of Diffusion-Based Adversarial Purification

Kaibo Wang, Xiaowen Fu, Yuxuan Han, Yang Xiang

NeurIPS 2024poster

Diffusion-based purification has demonstrated impressive robustness as an adversarial defense. However, concerns exist about whether this robustness arises from insufficient evaluation. Our research shows that EOT-based attacks face gradient dilemmas due to global gradient averaging, resulting in in…
