The mask token in BERT is a special token used during the pre-training phase. It randomly replaces a portion of the input text, typically 15%, and the model is then trained to predict these masked words based on the surrounding context. This strategy helps the model learn to infer missing words, enhancing its performance in downstream NLP tasks.

The mask token in BERT is a special token used to replace a certain percentage of words in the input text during the pre-training phase. This strategy aims to help the model learn to infer the masked words based on the context, thus improving its performance on downstream tasks. Typically, 15% of the tokens are chosen for masking, with 80% of those replaced by the [MASK] token, 10% replaced by random tokens, and the remaining 10% kept unchanged.
