Web16 feb. 2024 · The BERT family of models uses the Transformer encoder architecture to process each token of input text in the full context of all tokens before and after, hence the name: Bidirectional Encoder Representations from Transformers. BERT models are usually pre-trained on a large corpus of text, then fine-tuned for specific tasks. Setup BERT is based on the transformer architecture. Specifically, BERT is composed of Transformer encoder layers. BERT was pre-trained simultaneously on two tasks: language modeling (15% of tokens were masked, and the training objective was to predict the original token given its context) and next … Meer weergeven Bidirectional Encoder Representations from Transformers (BERT) is a family of masked-language models published in 2024 by researchers at Google.
