Point cloud models with neural network architectures have achieved great
success and have been widely used in safety-critical applications, such as
Lidar-based recognition systems in autonomous vehicles. However, such models
are shown vulnerable to adversarial attacks which aim to apply stealthy
semantic transformations such as rotation and tapering to mislead model
predictions. In this paper, we propose a transformation-specific smoothing
framework TPC, which provides tight and scalable robustness guarantees for
point cloud models against semantic transformation attacks. We first categorize …
