Self-Attention Graph Residual Convolutional Networks for Event Detection with dependency relations

no code implementations Findings (EMNLP) 2021 AnAn Liu, Ning Xu, Haozhe Liu

While existing GCN-based methods explore latent node-to-node dependency relations according to a stationary adjacency tensor, an attention-based dynamic tensor, which can pay much attention to the key node like event trigger or its neighboring nodes, has not been developed.

Better Fit: Accommodate Variations in Clothing Types for Virtual Try-on

no code implementations13 Mar 2024 Xuanpu Zhang, Dan Song, Pengxin Zhan, QingGuo Chen, Kuilong Liu, AnAn Liu

Image-based virtual try-on aims to transfer target in-shop clothing to a dressed model image, the objectives of which are totally taking off original clothing while preserving the contents outside of the try-on area, naturally wearing target clothing and correctly inpainting the gap between target clothing and original clothing.

TBNet:Two-Stream Boundary-aware Network for Generic Image Manipulation Localization

no code implementations10 Aug 2021 Zan Gao, Chao Sun, Zhiyong Cheng, Weili Guan, AnAn Liu, Meng Wang

In this work, a novel end-to-end two-stream boundary-aware network (abbreviated as TBNet) is proposed for generic image manipulation localization in which the RGB stream, the frequency stream, and the boundary artifact location are explored in a unified framework.
