EGTR-Review: Efficient Evidence-Grounded Scientific Peer Review Generation via Multi-Agent Teacher Distillation

2026-06-04 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning · Depth: Expert, quick

Summary

EGTR-Review is an Evidence-Grounded and Traceable Review Generation framework that enhances scientific peer review generation by addressing limitations of existing Large Language Model (LLM)-based methods, such as generic comments, insufficient evidence, and high inference costs from complex multi-agent systems. This framework first employs a multi-agent teacher to perform structure-aware paper decomposition, key-element extraction, external scholarly evidence retrieval, evidence-state labeling, verification reasoning, and review synthesis. Subsequently, it distills both intermediate reasoning trajectories and final review comments into a lightweight student model using task-prefix-driven multi-task learning. An evidence-weighted objective further refines supervision. Experiments on public datasets demonstrate EGTR-Review (Student) surpasses strong prompt-based, fine-tuned, and structured/agentic baselines across automatic metrics, LLM-as-Judge evaluation, and human evaluation, achieving strong factual grounding and source traceability with substantially lower token consumption and inference time.

Key takeaway

For Machine Learning Engineers developing LLM-based scientific review systems, you should consider adopting multi-agent teacher distillation to overcome issues of generic comments and high inference costs. This approach allows you to train lightweight student models that deliver evidence-grounded, traceable reviews with significantly lower token consumption and faster inference times, improving both quality and operational efficiency.
