This research introduces a multi-teacher collaborative distillation strategy to enable parameter-efficient deployment of large language models. The method achieves a perplexity of 20.8 and a BLEU score of 86.7 on the C4 dataset, demonstrating superior performance over existing distillation baselines and robust generalization across multiple NLP tasks.
Key insights
- Leveraging multiple teacher models provides a broader linguistic reference and richer contextual information, leading to substantial gains in student model performance.
- Dynamically weighting teachers based on their output information entropy (certainty) prioritizes more confident signals, enhancing learning efficiency and mitigating potential conflicts among teachers.
- Distilling intermediate semantic features in addition to output distributions enables the student model to capture deeper internal representations and achieve stronger language understanding and generation abilities.
