Self-Supervised 3D Point Cloud Detection with Depthwise Separable Masked Autoencoders

DS-MAE introduces a pyramidal transformer encoder with depthwise separable attention to enhance local geometric feature extraction while reducing computational cost and a density-aware reconstruction loss accounts for the non-uniform point density of LiDAR observations.
