Overview

We introduce Language Imbalance Driven Rewarding, a novel approach that leverages the inherent capability imbalance across different languages in large language models (LLMs) as a reward signal for iterative self-improvement. By applying iterative DPO training, our approach not only enhances the performance of non-dominant languages but also improves outcomes in dominant languages.

Our goal with this approach is to contribute a new perspective to the multilingual LLM community by challenging the assumption that language imbalance is solely a challenge to be mitigated. We hope this approach will inspire further exploration into multilingual self-improvement in LLMs, broadening the horizon for more balanced and capable language models.
