HilDA: Hierarchical Distillation with Diffusion Advances Self-Supervised LiDAR Pre-Training
Researchers propose HilDA, a self-supervised pretraining framework for LiDAR backbones that uses hierarchical distillation and temporal occupancy diffusion. The method achieves state-of-the-art results on cross-modal distillation benchmarks for 3D object detection, scene flow, and semantic occupancy prediction.
