Improved Lexically Constrained Decoding for Translation and Monolingual Rewriting

NAACL 2019 J. Edward HuHuda KhayrallahRyan CulkinPatrick XiaTongfei ChenMatt PostBenjamin Van Durme

Lexically-constrained sequence decoding allows for explicit positive or negative phrase-based constraints to be placed on target output strings in generation tasks such as machine translation or monolingual text rewriting. We describe vectorized dynamic beam allocation, which extends work in lexically-constrained decoding to work with batching, leading to a five-fold improvement in throughput when working with positive constraints...
