The RoBERTa (Robustly Optimized BERT Approach) model is a variant of the BERT (Bidirectional Encoder Representations from Transformers) model, specifically designed and trained for natural language processing (NLP) tasks. Built upon the Transformer architecture, RoBERTa employs a large-scale unsupervised pretraining process followed by fine-tuning on specific downstream tasks. The model excels in various NLP tasks, including text classification, named entity recognition, sentiment analysis, and more.
