arXiv:2606.19036v1 Announce Type: new Abstract: Sparse Mixture-of-Experts (SMoE) architectures are now widely deployed in state-of-the-art language and vision models, where conditional routing allows scaling to very large networks. However, this very Top-$k$ expert selection that enables conditional routing also renders the SMoE map inherently discontinuous. In the vicinity of these discontinuity surfaces, even inputs that are arbitrarily close may activate substantially different sets of experts resulting in significantly different outputs. In this work we give a rigorous geometric and stocha
The increasing deployment of state-of-the-art sparse Mixture-of-Experts (SMoE) models highlights inherent architectural challenges, making this analysis timely for future AI development.
Understanding and mitigating discontinuities in SMoE architectures is critical for developing more robust, reliable, and predictable large language and vision models, impacting their integration into safety-critical applications.
This research provides a foundational geometric and stochastic analysis, enabling better design principles and potential solutions for instability in high-performance AI models.
