Non Autoregressive Translation

Non-autoregressive translation (NAT) aims to accelerate machine translation by generating entire translations in a single forward pass, unlike the sequential approach of autoregressive methods. Current research focuses on mitigating NAT's inherent accuracy limitations through techniques like improved training objectives (e.g., modifications to cross-entropy loss), enhanced model architectures (e.g., incorporating directed acyclic graphs or hybrid autoregressive-non-autoregressive approaches), and leveraging pretrained language models. These advancements are significant because they offer the potential for substantially faster translation while striving to match the quality of established autoregressive systems, impacting both research and real-world applications requiring high-throughput translation.
