3DVerifier: Efficient Robustness Verification for 3D Point Cloud Models

1 code implementation15 Jul 2022 Ronghui Mu, Wenjie Ruan, Leandro S. Marcolino, Qiang Ni

Thus, we propose an efficient verification framework, 3DVerifier, to tackle both challenges by adopting a linear relaxation function to bound the multiplication layer and combining forward and backward propagation to compute the certified bounds of the outputs of the point cloud models.
