- R · What Makes It Special
- BERT (Bidirectional Encoder Representations from Transformers), Google's 2018 language model, the first deeply bidirectional one pre-trained only on plain text: it learns by predicting masked words from context on both sides and whether one sentence follows another, and fine-tunes with one added output layer. It set records on 11 NLP tasks, including 80.5% on GLUE and 93.2 F1 on SQuAD v1.1; Google open-sourced it that November and in 2019 used it to understand 1 in 10 US English searches.
