cambridgeltl/mirror-roberta-base-sentence-drophead

An unsupervised sentence encoder proposed by Liu et al. (2021), using drophead instead of dropout as feature space augmentation. The model is trained with unlabelled raw sentences, using roberta-base as the base model. Please use [CLS] (before pooler) as the representation of the input.

Note the model does not replicate the exact numbers in the paper since the reported numbers in the paper are average of three runs.
