21 Feb19 Issue #26 – Context and Copying in Neural MT Author: Raj Patel, Machine Translation Scientist @ Iconic When translating from one language to another, certain words and tokens need to be copied, and not translated, per se, in the target sentence. This includes things like proper nouns, names, numbers, and ‘unknown’ tokens. We want these to appear in the translation just as they were in the original text. Neural MT systems with subword vocabulary are capable of copying […]

01 Feb19 Issue #23 – Unbiased Neural MT Author: Raj Patel, Machine Translation Scientist @ Iconic A recent topic of conversation and interest in the area of Neural MT – and Artificial Intelligence in general – is gender bias. Neural models are trained using large text corpora which inherently contain social biases and stereotypes, and as a consequence, translation models inherit these biases. In this article, we’ll try to understand how gender bias affects the translation quality and discuss a […]

24 Jan19 Issue #22 – Mixture Models in Neural MT Author: Dr. Rohit Gupta, Sr. Machine Translation Scientist @ Iconic It goes without saying that Neural Machine Translation has become state of the art in MT. However, one challenge we still face is developing a single general MT system which works well across a variety of different input types. As we know from long-standing research into domain adaptation, a system trained on patent data doesn’t perform well when translating software documentation […]

17 Jan19 Issue #21 – Revisiting Data Filtering for Neural MT   Author: Dr. Patrik Lambert, Machine Translation Scientist @ Iconic The Neural MT Weekly is back for 2019 after a short break over the holidays! 2018 was a very exciting year for machine translation, as documented over the first 20 articles in this series. What was striking was the pace of development, even in the 6 months since we starting publishing these articles. This was illustrated by the fact […]

15 Nov18 Issue #17 – Speeding up Neural MT Author: Raj Nath Patel, Machine Translation Scientist @ Iconic For all the benefits Neural MT has brought in terms of translation quality, producing output quickly and efficiently is still a challenge for developers. All things being equal, Neural MT is slower than its statistical counterpart. This is particularly the case when running translation on standard processors (CPUs) as opposed to faster, more powerful (but also more expensive) graphics processors (GPUs), which is […]
