Beyond Distillation: Task-level Mixture-of-Experts for Efficient Inference (2021.findings-emnlp)

Copied to clipboard

Challenge: Sparse Mixture-of-Experts (MoE) is a successful approach for scaling multilingual translation models to billions of parameters without a proportional increase in training computation.
Approach: They propose to use a task-level routing approach to extract smaller, ready-to-deploy sub-networks from large sparse models by ignoring distillation.
Outcome: Experiments on WMT and a web-scale dataset show that task-level routing outperforms token-level MoE models by +1.0 BLEU on average across 30 language pairs.
