WebFeb 1, 2024 · Tokenization is the process of breaking down a piece of text into small units called tokens. A token may be a word, part of a word or just characters like punctuation. It is one of the most foundational NLP task and a difficult one, because every language has its own grammatical constructs, which are often difficult to write down as rules. WebJul 9, 2024 · Byte pair encoding (BPE) was originally invented in 1994 as a technique for data compression. Data was compressed by replacing commonly occurring pairs of consecutive bytes by a byte that wasn’t present in the data yet. In order to make byte pair encoding suitable for subword tokenization in NLP, some amendmends have been made.
