Researchers have introduced Non-Commutative State Space Models (NC-SSM) to address limitations in existing selective state space models like Mamba. These new models, including SO(3)-SSM and Cayley-SSM, extend state transitions to compact Lie groups, enabling exact norm-preserving isometry. Benchmarks demonstrate that NC-SSM significantly outperforms diagonal models in tracking complex groups such as A_5 and S_5, and preserves Riemannian manifolds with minimal drift. AI
