RoBERTa, which stands for Robustly optimized BERT approach, is a state-of-the-art natural language processing model built on the BERT architecture but optimized for better performance. By using larger training datasets and removing the Next Sentence Prediction objective, RoBERTa improves on its predecessor's capabilities, particularly in tasks like named entity recognition and part-of-speech tagging where understanding context and relationships in text is crucial.
