The short version
  • Researchers have proposed Riemannian Language Models (RiLM) to address efficiency bottlenecks in models under one million parameters.
  • The RiLM method uses geodesic decoding to bypass the standard output projection matrix, which typically consumes up to a third of model capacity.
