📘 Summary

The quality of large language model (LLM) outputs in machine translation (MT) strongly depends on the in-context examples (ICEs) provided along with the input text.
Selecting the most effective examples typically requires reference translations or human judgment — both costly and impractical at scale.

Our method, ICLviaQE, introduces a quality-estimation-guided in-context learning framework that selects and orders examples based on predicted translation quality, without using reference translations.
By leveraging XGLM as a QE estimator, the system automatically identifies the most beneficial examples, leading to consistent improvements across domains and outperforming fine-tuned mBART-50 baselines.
