Generalized Visual Relation Detection with Diffusion Models

no code implementations16 Apr 2025 Kaifeng Gao, Siqi Chen, Hanwang Zhang, Jun Xiao, Yueting Zhuang, Qianru Sun

To this end, we propose to model visual relations as continuous embeddings, and design diffusion models to achieve generalized VRD in a conditional generative manner, termed Diff-VRD.

This structured decomposition enables systematic understanding of both interface layouts and visual relationships.

Integrating Graph Neural Networks and Many-Body Expansion Theory for Potential Energy Surfaces

1 code implementation3 Nov 2024 Siqi Chen, Zhiqiang Wang, Xianqi Deng, Yili Shen, Cheng-Wei Ju, Jun Yi, Lin Xiong, Guo Ling, Dieaa Alhmoud, Hui Guan, Zhou Lin

Rational design of next-generation functional materials relied on quantitative predictions of their electronic structures beyond single building blocks.

pFedGPA: Diffusion-based Generative Parameter Aggregation for Personalized Federated Learning

no code implementations9 Sep 2024 Jiahao Lai, Jiaqi Li, Jian Xu, Yanru Wu, Boshi Tang, Siqi Chen, Yongfeng Huang, Wenbo Ding, Yang Li

In this framework, we deploy a diffusion model on the server to integrate the diverse parameter distributions and propose a parameter inversion method to efficiently generate a set of personalized parameters for each client.
