Researchers have introduced a novel attention mechanism called Lie-Algebra Attention, which treats tokens as elements of a matrix Lie group. This approach allows attention scores to be derived from the intrinsic geometry of relative poses rather than relying on learned kernels. Experiments on sequence completion tasks involving SE(2), SO(3), and Aff(2) demonstrate that this closed-form score matches or outperforms learned MLP kernels, using significantly fewer parameters and maintaining invariance.
