BERT#
Released in 2018, Bidirectional Representations from Transformers (BERT) is a encoder-only transformer network augmented with its namesake bidirectional layers. BERT has become a staple in the Natural Language Processing domain, and the ideas in the original paper have been adapted to many different domains and applications.
