Equifinality in Mixture of Experts: Routing Topology Does Not Determine Language Modeling Quality

📰 ArXiv cs.AI

Discover how routing topology in Mixture of Experts doesn't determine language modeling quality, and learn to build a geometric MoE with cosine-similarity routing

advanced Published 17 Apr 2026
Action Steps
  1. Build a geometric MoE (ST-MoE) using cosine-similarity routing against learned centroids in a low-dimensional space
  2. Compare the performance of ST-MoE with standard linear routers
  3. Apply cosine-similarity routing to reduce routing parameters by 80%
  4. Test the language modeling quality of the ST-MoE architecture
  5. Configure the routing mechanism to optimize language modeling performance
