Overview. The RoBERTa model was proposed in RoBERTa: A Robustly Optimized BERT Pretraining Approach by Yinhan Liu, Myle Ott, Naman Goyal, Jingfei Du, Mandar Joshi, Danqi Chen, Omer Levy, Mike Lewis, Luke Zettlemoyer, Veselin Stoyanov. It is based on Google’s BERT model released in 2018.
Jan 10, 2023 · RoBERTa (short for “Robustly Optimized BERT Approach”) is a variant of the BERT (Bidirectional Encoder Representations from Transformers) model, which was developed by researchers at Facebook AI.
Jun 28, 2021 · Let’s look at the development of a robustly optimized method for pretraining natural language processing (NLP) systems (RoBERTa). Open Source BERT by Google. Bidirectional Encoder Representations...
Jul 26, 2019 · RoBERTa: A Robustly Optimized BERT Pretraining Approach. Yinhan Liu, Myle Ott, Naman Goyal, Jingfei Du, Mandar Joshi, Danqi Chen, Omer Levy, Mike Lewis, Luke Zettlemoyer, Veselin Stoyanov. Language model pretraining has led to significant performance gains but careful comparison between different approaches is challenging.
RoBERTa is a transformers model pretrained on a large corpus of English data in a self-supervised fashion. This means it was pretrained on the raw texts only, with no humans labelling them in any way (which is why it can use lots of publicly available data) with an automatic process to generate inputs and labels from those texts.
Model Description. Bidirectional Encoder Representations from Transformers, or BERT, is a revolutionary self-supervised pretraining technique that learns to predict intentionally hidden (masked) sections of text.
Jul 29, 2019 · Facebook AI’s RoBERTa is a new training recipe that improves on BERT, Google’s self-supervised method for pretraining natural language processing systems. By training longer, on more data, and dropping BERT’s next-sentence prediction RoBERTa topped the GLUE leaderboard.

Nov 9, 2022 · RoBERTa is a reimplementation of BERT with some modifications to the key hyperparameters and tiny embedding tweaks, along with a setup for RoBERTa pre-trained models. In RoBERTa, we don’t need to define which token belongs to which segment or use token_type_ids.
Sep 24, 2023 · RoBERTa uses bytes instead of unicode characters as the base for subwords and expands the vocabulary size up to 50K without any preprocessing or input tokenization. This results in 15M and 20M additional parameters for BERT base and BERT large models respectively.
