transformer model, typically used to improve performance in multilingual or multi-task natural language processing.

RoBERTa, developed by Facebook AI, is a transformer-based model that improved upon BERT by training on more data, using dynamic masking, and removing the Next Sentence Prediction (NSP) objective. It consistently outperforms BERT on GLUE, SuperGLUE, and SQuAD benchmarks. wals roberta sets top

RoBERTa, short for Robustly Optimized BERT Pretraining Approach, is a variant of the BERT (Bidirectional Encoder Representations from Transformers) model, developed by Facebook AI in 2019. RoBERTa was designed to improve upon the original BERT model by optimizing its pretraining approach, leading to better performance on a wide range of natural language processing (NLP) tasks.
