TransAug: Translate as Augmentation for Sentence Embeddings

no code implementations30 Oct 2021 Jue Wang, Haofan Wang, Xing Wu, Chaochen Gao, Debing Zhang

In this paper, we present TransAug (Translate as Augmentation), which provide the first exploration of utilizing translated sentence pairs as data augmentation for text, and introduce a two-stage paradigm to advances the state-of-the-art sentence embeddings.
