Researchers have developed GEM, a generative LiDAR world model designed to simulate environmental dynamics for autonomous driving. The model utilizes a deformable Mamba architecture to overcome challenges with disordered LiDAR point clouds and distinguishing dynamic from static objects. GEM tokenizes LiDAR sweeps, separates dynamic and static features, and then processes them through a tri-path Mamba for enhanced spatio-temporal understanding, achieving state-of-the-art results on various benchmarks.
