Sentence -BERT: Sentence Embeddings using Siamese BERT-NetworksNils Reimers and Iryna GurevychUbiquitous Knowledge Processing Lab (UKP-TUDA)Department of Computer Science, Technische Universit at (Devlin et al., 2018) and RoBERTa (Liuet al., 2019) has set a new state-of-the-artperformance on Sentence -pair regression taskslike semantic textual similarity (STS). How-ever, it requires that both sentences are fedinto the network, which causes a massive com-putational overhead: Finding the most sim-ilar pair in a collection of 10,000 sentencesrequires about 50 million inference computa-tions (~65 hours) with BERT.
2017). RoBERTa (Liu et al.,2019) showed, that the performance of BERT can further improved by small adaptations to the pre-training process. We also tested XLNet (Yang et al.,2019), but it led in general to worse results than BERT. A large disadvantage of the BERT network structure is that no independent sentence embed-
