Fine-Grained Reward Optimization for Machine Translation using Error Severity Mappings (2026.tacl-1)

Copied to clipboard

Challenge: Reinforcement learning (RL) is an effective and robust method for training neural machine translation systems.
Approach: They propose a method that leverages fine-grained, token-level quality assessments . they use a state-of-the-art quality estimation system as their token- level reward model .
Outcome: The proposed approach leverages fine-grained, token-level quality assessments along with error severity levels to improve translation quality.
