Talk Title: Qualitative Analysis of Unsupervised Neural Machine Translation
Series: NL Seminar
Abstract: Supervised neural machine translation SNMT models built on all the available parallel data result in higher BLEU on test sets than unsupervised neural machine translation UNMT models leveraging all available monolingual data.
Recently UNMT models such as XLM and MASS are reducing the gap with SNMT in terms of BLEU. Prior work has shown that linguistic and domain dissimilarity often hinder UNMTs performance. The question we're asking in this investigation is, when SNMT and UNMT do have comparable BLEU, do they exhibit qualitative differences, and if these differences can be detected by other metrics.
Biography: Weiqiu You is a rising first year PhD student at University of Pennsylvania who just graduated with MS from UMass Amherst. Her interests include machine translation and natural language processing in general.
