Abstract: Various studies have been undertaken to learn point cloud representations that are both discriminative and robust. However, most of them suffer from rotation disturbance and insufficient ...

We develop a new physical-world backdoor threat model via rotation transformation, and demonstrate its effectiveness on image classification and object detection task.

Abstract: Least-squares reverse time migration (LSRTM) can estimate high-quality reflectivity of subsurface medium from seismic data. However, the subsurface reflectivity depends on reflection angles, ...
