POINTACL: Adversarial Contrastive Learning for Robust Point Clouds Representation Under Adversarial Attack
ICASSP 2023accepted
Adversarial contrastive learning (ACL) is considered an effective way to improve the robustness of pre-trained models. In contrastive learning, a projector which consists of multilayer perceptron (MLP) will project high dimension 3D point cloud feature into low dimension for calculating contrastive…
