Overview

Novel contrastive representation improves modularization and specialization in mixture-of-experts models, enhancing performance.

Key Points

  • CoMoE enhances the capacity of mixture-of-experts, promoting better specialization among experts in model training.
  • Experiments demonstrated improvements across various benchmarks, suggesting enhanced performance in heterogeneous datasets.
  • The method uses a contrastive objective that recovers information gaps between activated and inactivated experts.
  • The study emphasizes the importance of effective module training for optimal use of expert capacities.
