On Learning Form and Meaning in Neural Machine Translation Models
Neural machine translation (MT) models obtain state-of-the-art performance while maintaining a simple, end-to-end architecture. However, interpreting such models remains challenging and not much is known about what they learn about source and target languages during the training process. In this talk, I will present our recent work on investigating what neural MT models learn about linguistic properties. We analyze the representations learned by neural MT models at various levels of granularity and empirically evaluate the quality of the representations through extrinsic classification tasks. First, we utilize part-of-speech and morphological tagging tasks to evaluate morphological learning in neural MT models. We conduct a thorough investigation along several parameters: word-based vs. character-based representations, depth of the encoding layer, the identity of the target language, and encoder vs. decoder representations. Second, we analyze what kind of semantic information is captured in neural MT models through a semantic tagging task. Our data-driven, quantitative evaluation sheds light on important aspects in the neural MT system and its ability to capture the form and meaning of words.
