Bpe tokenization
WebByte Pair Encoding (BPE) - Handling Rare Words with Subword Tokenization ¶ NLP techniques, be it word embeddings or tfidf often works with a fixed vocabulary size. Due to this, rare words in the corpus would all be considered out of vocabulary, and is often times replaced with a default unknown token, .
