About this paper

Yang Su, Na Yan, Yansha Deng, Robert Schober

The PWC-MoE framework introduces a privacy-aware Mixture of Experts model designed for wireless collaborative systems, dynamically routing sensitive input tokens for local processing while intelligently offloading non-sensitive tokens to a base station based on importance and bandwidth constraints. This system aims to balance computational cost, model performance, and data privacy in resource-limited environments.

Key insights

  • Fine-grained token-level privacy control, by routing sensitive tokens locally, can effectively protect user data without compromising the overall model's capability.
  • Sparse Mixture of Experts architectures, when deployed collaboratively, can optimize resource utilization across local and remote computation nodes.
  • Predicting token importance enables efficient use of limited wireless bandwidth, allowing high performance with a reduced number of transmitted tokens.
