GUARD: Graph Universal Adversarial Defense

1 code implementation20 Apr 2022 Jintang Li, Jie Liao, Ruofan Wu, Liang Chen, Jiawang Dan, Changhua Meng, Zibin Zheng, Weiqiang Wang

Graph convolutional networks (GCNs) have shown to be vulnerable to small adversarial perturbations, which becomes a severe threat and largely limits their applications in security-critical scenarios.

1st Place Solution for Waymo Open Dataset Challenge -- 3D Detection and Domain Adaptation

no code implementations28 Jun 2020 Zhuangzhuang Ding, Yihan Hu, Runzhou Ge, Li Huang, Sijia Chen, Yu Wang, Jie Liao

We proposed a one-stage, anchor-free and NMS-free 3D point cloud object detector AFDet, using object key-points to encode the 3D attributes, and to learn an end-to-end point cloud object detection without the need of hand-engineering or learning the anchors.
