Researchers have introduced Manifold-Aligned Point Recognition (MAPR), a new framework designed to enhance the robustness of 3D point cloud networks against adversarial attacks. MAPR addresses the geometric root cause of vulnerability by aligning the latent geometry learned by the model with the intrinsic geometry of the underlying surface. This approach regularizes the latent geometry by ensuring predictions remain consistent across intrinsic perturbations, without requiring adversarial training or additional data. MAPR demonstrated significant robustness improvements on the ModelNet40 and ScanObjectNN datasets, achieving average gains of over 20% and 8% respectively. AI
