LLM-Enhanced User-Item Interactions: Leveraging Edge Information for Optimized Recommendations

1 code implementation14 Feb 2024 Xinyuan Wang, Liang Wu, Liangjie Hong, Hao liu, Yanjie Fu

Additionally, we introduce graph relationship understanding and analysis functions into LLMs to enhance their focus on connectivity information in graph data.

Leveraging Frequency Domain Learning in 3D Vessel Segmentation

no code implementations11 Jan 2024 Xinyuan Wang, Chengwei Pan, Hongming Dai, Gangming Zhao, Jinpeng Li, Xiao Zhang, Yizhou Yu

In this study, we leverage Fourier domain learning as a substitute for multi-scale convolutional kernels in 3D hierarchical segmentation models, which can reduce computational expenses while preserving global receptive fields within the network.
