Before revision:  Non-autoregressive translation techniques, on the other hand, parallelize generation across positions and speed up inference at the expense of translation quality. Much recent effort has been devoted to non-autoregressive methods, aiming for a better balance between speed and quality .
After revision:  Non-autoregressive machine translation provides a tradeoff between translation quality and inference speed, but some of the latest models have achieved impressive tradeoffs compared to autoregressive baselines .
