The authors show that incorporating contextualized word vectors (CoVe), generated by the MT encoder, into models for tasks like sentiment analysis, question classification, entailment, and question answering significantly improves performance. These context vectors capture word meaning in the context of a sentence, which allows for better transfer learning compared to using only unsupervised word vectors. The authors demonstrate that larger and more complex MT datasets lead to higher-quality CoVe representations, resulting in greater performance gains for downstream NLP tasks. They further explore how combining CoVe with other types of word embeddings, such as character n-grams, can further boost model performance. 原文链接：arxiv.org
