RoBERTa

TECHNICAL DEFINITION

RoBERTa (Robustly Optimized BERT approach) is a Facebook AI-developed language model that builds upon BERT by optimizing pretraining strategies, including dynamic masking, larger batch sizes, and training on significantly more data for longer, leading to improved performance on various NLP benchmarks.

BACKGROUND

Bidirectional encoder representations from transformers (BERT) is a language model introduced in October 2018 by researchers at Google. It learns to represent text as a sequence of vectors using self-supervised learning. It uses the encoder-only transformer architecture. BERT dramatically improved the state of the art for large language models. As of 2020, BERT is a ubiquitous baseline in natural language processing (NLP) experiments.
