SuperLine3D: Self-supervised Line Segmentation and Description for LiDAR Point Cloud

1 code implementation3 Aug 2022 Xiangrui Zhao, Sheng Yang, Tianxin Huang, Jun Chen, Teng Ma, Mingyang Li, Yong liu

To repetitively extract them as features and perform association between discrete LiDAR frames for registration, we propose the first learning-based feature segmentation and description model for 3D lines in LiDAR point cloud.

High-Dimensional Stochastic Gradient Quantization for Communication-Efficient Edge Learning

no code implementations9 Oct 2019 Yuqing Du, Sheng Yang, Kaibin Huang

First, the framework features a practical hierarchical architecture for decomposing the stochastic gradient into its norm and normalized block gradients, and efficiently quantizes them using a uniform quantizer and a low-dimensional codebook on a Grassmann manifold, respectively.

Learning Markov Clustering Networks for Scene Text Detection

no code implementations CVPR 2018 Zichuan Liu, Guosheng Lin, Sheng Yang, Jiashi Feng, Weisi Lin, Wang Ling Goh

MCN predicts instance-level bounding boxes by firstly converting an image into a Stochastic Flow Graph (SFG) and then performing Markov Clustering on this graph.

Flint Water Crisis: Data-Driven Risk Assessment Via Residential Water Testing

no code implementations30 Sep 2016 Jacob Abernethy, Cyrus Anderson, Chengyu Dai, Arya Farahi, Linh Nguyen, Adam Rauh, Eric Schwartz, Wenbo Shen, Guangsha Shi, Jonathan Stroud, Xinyu Tan, Jared Webb, Sheng Yang

In this analysis, we find that lead service lines are not the only factor that is predictive of the risk of lead contamination of water.
