By Semere Gerezgiher Tesfay Introduction Autonomous driving relies heavily on robust 3D perception systems, which require large-scale labeled datasets for training. However, annotating 3D data (LiDAR, camera) is expensive and time-consuming. Self-supervised learning (SSL) offers a solution by leveraging unlabeled data, but existing methods often borrow ideas from 2D vision without addressing 3D-specific challenges like sparsity and irregularity in point clouds. Enter UniPAD, a novel SSL framew
