Masked language modeling - Hugging Face
Masked language modeling is great for tasks that require a good contextual understanding of an entire sequence. BERT is an example of a masked language model. This guide will show you how to: Finetune DistilRoBERTa on the r/askscience subset of the ELI5 dataset. Use your finetuned model for inference.

How to Train BERT for Masked Language Modeling Tasks
2023年10月17日 · We introduce a new language representation model called BERT, which stands for Bidirectional Encoder Representations from Transformers. 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.
BERT - Hugging Face
BERT was trained with the masked language modeling (MLM) and next sentence prediction (NSP) objectives. It is efficient at predicting masked tokens and at NLU in general, but is not optimal for text generation. Corrupts the inputs by using random masking, more precisely, during pretraining, a given percentage of tokens (usually 15%) is masked by:
Masked-Language Modeling With BERT - Towards Data Science
2021年5月19日 · BERT has enjoyed unparalleled success in NLP thanks to two unique training approaches, masked-language modeling (MLM), and next sentence prediction (NSP). In many cases, we might be able to take the pre-trained BERT model out-of-the-box and apply it successfully to our own language tasks.
End-to-end Masked Language Modeling with BERT - Keras
2020年9月18日 · This example teaches you how to build a BERT model from scratch, train it with the masked language modeling task, and then fine-tune this model on a sentiment classification task. We will use the Keras TextVectorization and MultiHeadAttention layers to create a BERT Transformer-Encoder network architecture.
Fine-tuning a masked language model - Hugging Face NLP Course
Although the BERT and RoBERTa family of models are the most downloaded, we’ll use a model called DistilBERT that can be trained much faster with little to no loss in downstream performance.
