Subword Secrets: The Intricacies and Impact of BPE Tokenization
The article delves into Byte Pair Encoding (BPE) as a subword tokenization method in natural language processing (NLP). It compares BPE with k-mer tokenization, highlighting BPE's advantages in handling unknown words and preventing token leakage. However, the article notes that BPE may face challenges in fields like computational biology, particularly in genomics, due to its limitations in capturing complex biological sequences.
