Improved Neural Machine Translation using Side Information
Cong Duy Vu Hoang | Gholamreza Haffari | Trevor Cohn
Proceedings of the Australasian Language Technology Association Workshop 2018

In this work, we investigate whether side information is helpful in neural machine translation (NMT). We study various kinds of side information, including topical information, personal trait, then propose different ways of incorporating them into the existing NMT models. Our experimental results show the benefits of side information in improving the NMT models.

Towards Decoding as Continuous Optimisation in Neural Machine Translation
Cong Duy Vu Hoang | Gholamreza Haffari | Trevor Cohn
Proceedings of the 2017 Conference on Empirical Methods in Natural Language Processing

We propose a novel decoding approach for neural machine translation (NMT) based on continuous optimisation. We reformulate decoding, a discrete optimization problem, into a continuous problem, such that optimization can make use of efficient gradient-based techniques. Our powerful decoding framework allows for more accurate decoding for standard neural machine translation models, as well as enabling decoding in intractable models such as intersection of several different NMT models. Our empirical results show that our decoding framework is effective, and can leads to substantial improvements in translations, especially in situations where greedy search and beam search are not feasible. Finally, we show how the technique is highly competitive with, and complementary to, reranking.
