Jan 10, 2023 · RoBERTa stands for Robustly Optimized BERT Pre-training Approach. It was presented by researchers at Facebook and Washington University. The goal of this paper was to optimize the training of BERT architecture in order to take lesser time during pre-training.
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. It builds on BERT and modifies key hyperparameters, removing the next-sentence pretraining objective and training with much larger mini-batches and learning rates.
Jun 28, 2021 · Open Source BERT by Google. Bidirectional Encoder Representations from Transformers, or BERT, is a self-supervised method released by Google in 2018.. BERT is a tool/model which understand ...
Jul 26, 2019 · Language model pretraining has led to significant performance gains but careful comparison between different approaches is challenging. Training is computationally expensive, often done on private datasets of different sizes, and, as we will show, hyperparameter choices have significant impact on the final results. We present a replication study of BERT pretraining (Devlin et al., 2019) that carefully measures the impact of many key hyperparameters and training data size. We find that BERT ...
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.
RoBERTa base model Pretrained model on English language using a masked language modeling (MLM) objective. It was introduced in this paper and first released in this repository.This model is case-sensitive: it makes a difference between english and English.

May 23, 2024 · RoBERTa (short for “Robustly Optimized BERT Approach”) is an advanced version of the BERT (Bidirectional Encoder Representations from Transformers) model, created by researchers at Facebook AI…
RoBERTa is an extension of BERT with changes to the pretraining procedure. The modifications include: training the model longer, with bigger batches, over more data removing the next sentence prediction objective training on longer sequences dynamically changing the masking pattern applied to the training data. The authors also collect a large new dataset ($\text{CC-News}$) of comparable size to other privately used datasets, to better control for training set size effects
Sep 24, 2023 · Pretraining. Apart from it, RoBERTa applies all four described aspects above with the same architecture parameters as BERT large. The total number of parameters of RoBERTa is 355M.
