The Transformer Bidirectional Encoder Representations aka BERT has shown strong empirical performance therefore BERT will certainly continue to be a core method in NLP for years to come. BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding. Intuitively, it is reasonable to believe that a deep bidirectional model is strictly more powerful than either a left-to-right model or the shallow concatenation of a left-to-right and right-to-left model. E.g., 10x-100x bigger model trained for 100x-1,000x as many steps. As of 2019, Google has been leveraging BERT to better understand user searches..

The Transformer Bidirectional Encoder Representations aka BERT has shown strong empirical performance therefore BERT will certainly continue to be a core method in NLP for years to come. BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding. Intuitively, it is reasonable to believe that a deep bidirectional model is strictly more powerful than either a left-to-right model or the shallow concatenation of a left-to-right and right-to-left model. E.g., 10x-100x bigger model trained for 100x-1,000x as many steps. As of 2019, Google has been leveraging BERT to better understand user searches..

BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding (2019) Bidirectional Encoder Representations from Transformers (BERT) is a language representation model introduced by authors from Google AI language. Using BERT has two stages: Pre-training and fine-tuning. Unlike recent language representation models, BERT is designed to pretrain deep bidirectional representations by jointly conditioning on both left and right context in all layers. The pre-trained BERT model can be fine-tuned with an additional output layer to create state-of-the-art models for a wide range of NLP tasks. In this tutorial we will apply DeepSpeed to pre-train the BERT (Bidirectional Encoder Representations from Transformers), which is widely used for many Natural Language Processing (NLP) tasks. The BERT model was proposed in BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding by Jacob Devlin, Ming-Wei Chang, Kenton Lee and Kristina Toutanova. Paper Dissected: “Attention is All You Need” Explained Masked Language Model (MLM) In this task, 15% of the tokens from each sequence are randomly masked (replaced with the token [MASK]). About: In this paper, … Bidirectional Encoder Representations from Transformers BERT (Devlin et al., 2018) is a language representation model that combines the power of pre-training with the bi-directionality of the Transformer’s encoder (Vaswani et al., 2017). Unlike recent language representation models, BERT is designed to pre-train deep bidirectional representations from unlabeled text by jointly conditioning on both left and right context in all layers. In the field of computer vision, researchers have repeatedly shown the value of transfer learning — pre-training a neural network model on a known task, for instance ImageNet, and then performing fine-tuning — using the trained neural network as the basis of a new purpose-specific model.
