Learning Attributed Graph Representations with Communicative Message Passing Transformer

1 code implementation19 Jul 2021 Jianwen Chen, Shuangjia Zheng, Ying Song, Jiahua Rao, Yuedong Yang

For this sake, we propose a Communicative Message Passing Transformer (CoMPT) neural network to improve the molecular graph representation by reinforcing message interactions between nodes and edges based on the Transformer architecture.

Lossless Point Cloud Attribute Compression with Normal-based Intra Prediction

no code implementations23 Jun 2021 Qian Yin, Qingshan Ren, Lili Zhao, Wenyi Wang, Jianwen Chen

In this paper, we propose a normal-based intra prediction scheme, which provides a more efficient lossless attribute compression by introducing the normals of point clouds.

RAI-Net: Range-Adaptive LiDAR Point Cloud Frame Interpolation Network

no code implementations1 Jun 2021 Lili Zhao, Zezhi Zhu, Xuhu Lin, Xuezhou Guo, Qian Yin, Wenyi Wang, Jianwen Chen

In this paper, we propose a novel LiDAR point cloud frame interpolation method, which exploits range images (RIs) as an intermediate representation with CNNs to conduct the frame interpolation process.
