Reward-Guided Self-Training Improves Pronoun Translation in Context-Aware MT
A new arXiv paper examines how context-aware machine translation systems handle pronouns, which depend on discourse information that ordinary fine-tuning tends not to emphasize. The authors propose ProNMT, a self-training approach that uses reward signals to iteratively refine these sparse, context-sensitive decisions while keeping overall translation quality balanced. The work targets the trade-off between general fluency and accurate pronoun-specific output.
