Collateral Damage Constrained Backdoor Attacks on Graph Neural Networks

IJCAI 2026

Graph Neural Networks (GNNs) are vulnerable to backdoor attacks, where models behave normally on clean data but exhibit targeted misclassifications once specific triggers are activated. Existing backdoor attacks on GNNs mainly focus on enhancing trigger stealthiness or diversifying attack paradigms.

Enabling Instructional Image Editing with In-Context Generation in Large Scale Diffusion Transformer

NeurIPS 2025poster

Instruction-based image editing enables precise modifications via natural language prompts, but existing methods face a precision-efficiency tradeoff: fine-tuning demands massive datasets (>10M) and computational resources, while training-free approaches suffer from weak instruction comprehension.…

SIFU: Side-view Conditioned Implicit Function for Real-world Usable Clothed Human Reconstruction

CVPR 2024highlight

Creating high-quality 3D models of clothed humans from single images for real-world applications is crucial. Despite recent advancements accurately reconstructing humans in complex poses or with loose clothing from in-the-wild images along with predicting textures for unseen areas remains a signific…

Global-correlated 3D-decoupling Transformer for Clothed Avatar Reconstruction

NeurIPS 2023poster

Reconstructing 3D clothed human avatars from single images is a challenging task, especially when encountering complex poses and loose clothing. Current methods exhibit limitations in performance, largely attributable to their dependence on insufficient 2D image features and inconsistent query metho…
