FLEX-MoE: Federated Mixture-of-Experts for Resource-Constrained FL
Analysis
This paper addresses the challenges of deploying Mixture-of-Experts (MoE) models in federated learning (FL) environments, specifically focusing on resource constraints and data heterogeneity. The key contribution is FLEX-MoE, a framework that optimizes expert assignment and load balancing to improve performance in FL settings where clients have limited resources and data distributions are non-IID. The paper's significance lies in its practical approach to enabling large-scale, conditional computation models on edge devices.
Key Takeaways
- •Addresses resource constraints and data heterogeneity in Federated Learning (FL) for MoE models.
- •Proposes FLEX-MoE, a framework for optimized expert assignment and load balancing.
- •Employs client-expert fitness scores and an optimization-based algorithm.
- •Aims to improve performance and maintain balanced expert utilization in FL settings.
“FLEX-MoE introduces client-expert fitness scores that quantify the expert suitability for local datasets through training feedback, and employs an optimization-based algorithm to maximize client-expert specialization while enforcing balanced expert utilization system-wide.”
