Enhancing Local Geometry Learning for 3D Point Cloud via Decoupling Convolution

no code implementations4 Jul 2022 Haoyi Xiu, Xin Liu, Weimin WANG, Kyoung-Sook Kim, Takayuki Shinohara, Qiong Chang, Masashi Matsuoka

Modeling the local surface geometry is challenging in 3D point cloud understanding due to the lack of connectivity information.

Enhancing Local Feature Learning for 3D Point Cloud Processing using Unary-Pairwise Attention

no code implementations1 Mar 2022 Haoyi Xiu, Xin Liu, Weimin WANG, Kyoung-Sook Kim, Takayuki Shinohara, Qiong Chang, Masashi Matsuoka

We present a simple but effective attention named the unary-pairwise attention (UPA) for modeling the relationship between 3D point clouds.

DeepUrbanEvent: A System for Predicting Citywide Crowd Dynamics at Big Events

1 code implementation 25th ACM SIGKDD International Conference on Knowledge Discovery & Data Mining 2019 Renhe Jiang, Xuan Song, Dou Huang, Xiaoya Song, Tianqi Xia, Zekun Cai, Zhaonan Wang, Kyoung-Sook Kim, Ryosuke Shibasaki

Therefore in this study, we aim to extract the “deep” trend only from the current momentary observations and generate an accurate prediction for the trend in the short future, which is considered to be an effective way to deal with the event situations.
