The ultimate goal of AI is a world taking care of itself,
so the humans can finally become a pack of carefree, barefooted,
long-haired hippies. (← irony)

Last week, I discussed a paper claiming that forward-translation might be a better data augmentation technique than back-translation. This week, I will follow with a paper that touches a similar topic, but in a slightly different context. The title of the paper is Understanding Knowledge Distillation in Non-Autoregressive Machine Translation and was...

Does WMT speak translationese? And who else speaks translationese? Is the success of back-translation fake news? These are the questions that implicitly ask authors of a paper called Domain, Translationese and Noise in Synthetic Data for Neural Machine Translation that was uploaded on arXiv earlier...

Everyone who followed natural language processing on Twitter last week must have noticed a paper called BPE-Dropout: Simple and effective Subword Regularizations that introduces a simple way of adding stochastic noise into text segmentation to increase model robustness. It sounds complicated, but it is fairly easy. As...

One of the biggest limitations of current machine translation systems is they only work with isolated sentences. The systems need to guess when it comes to phenomena that cross the (often rather arbitrary) sentence boundaries. The typical example that is mentioned everywhere is the translation...

One of the topics I am currently dealing with in my research is character-level modeling for neural machine translation. Therefore, I was glad to see a paper that appeared on arXiv last week called On the Importance of Word Boundaries in Character-level Neural Machine Translation that shows an interesting...

Neural machine translation is based on machine learning—we collect training data, pairs of parallel sentences which we hope represent how language is used in the two languages, and train models using the data. When the model is trained, the more the input resembles the sentences...

It’s time to talk about gender—why things go wrong with gender in machine translation and what people do about it. Some languages have gendered nouns (German), some have gendered almost everything (Czech, French) and some only few pronouns (English). Let’s say you want to translate...

Machine translation is typically trained on bilingual data that can be found on the Internet. It mostly comes from international government and non-government organizations, commercial web presentations, books, movie subtitles, etc. Therefore, most of the text is quite formal and almost without typos and certainly...
