Byte-pair encoding tokenizer

WebByte Pair Encoding, or BPE, is a subword segmentation algorithm that encodes rare and unknown words as sequences of subword units. The intuition is that various word classes are translatable via smaller units than words, for instance names (via character copying or transliteration), compounds (via compositional translation), and cognates and loanwords … WebAfter training a tokenizer with Byte Pair Encoding (BPE), a new vocabulary is built with newly created tokens from pairs of basic tokens. This vocabulary can be accessed with tokenizer.vocab_bpe, and binds tokens as bytes (string) to their associated ids (int). This is the vocabulary of the 🤗tokenizers BPE model.
