ZurichNLP/unsup-simcse-xlm-roberta-base

xlm-roberta-base fine-tuned for sentence embeddings with SimCSE (Gao et al., EMNLP 2021).

See a similar English model released by Gao et al.: https://huggingface.co/princeton-nlp/unsup-simcse-roberta-base.

Fine-tuning was done using the reference implementation of unsupervised SimCSE and the 1M sentences from English Wikipedia released by the authors. As a sentence representation, we used the average of the last hidden states (pooler_type=avg), which is compatible with Sentence-BERT.

Fine-tuning command:
