“This article describes a simple general-purpose data compression algorithm, called Byte Pair Encoding (BPE)” 也就是一个压缩算法。 BPE 现如今的主要职责是?作为分词算法,构建词表并进行编码与解码。 为什么需要专门的分词算法,又为什么选择 BPE 而不是其他的压缩编码算
Byte Pair Encoding简称BPE,本质上是一个数据压缩算法。其通过迭代式地“合并高频字符对”,保留出现最多子词的方式,达到压缩总编码词表的目的。 我们知道在NLP世界中,分词是非常重要的,顾名思义是一种文本信息分割手段,分词的目的是把文本信息转化成数字信息,毕竟计算机只认数字嘛,这些数字我们称之为token,因此分词...
Minimal, clean code for the (byte-level) Byte Pair Encoding (BPE) algorithm commonly used in LLM tokenization. The BPE algorithm is "byte-level" because it runs on UTF-8 encoded strings. This algorithm was popularized for LLMs by the GPT-2 paper and the associated GPT-2 code release fro...
Minimal, clean code for the Byte Pair Encoding (BPE) algorithm commonly used in LLM tokenization. - 9D-AI/minbpe
The popular one among these tokenizers is thesubword-based tokenizer. This tokenizer is used by most state-of-the-artNLPmodels. So let’s get started with knowing first what subword-based tokenizers are and then understanding the Byte-Pair Encoding (BPE) algorithm used by the state-of-the-...
Motivated by this challenge, this paper employs Byte Pair Encoding (BPE) algorithm for password segmentation, extracting those non-semantical patterns which are frequently used in passwords subconsciously by people. Based on the segmentation, we propose a BPE-PCFGs model to generate password guesses....

Byte 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 (...
Byte pair encoding (BPE) algorithm was suggested by P. Gage is to achieve data compression. It encodes all instances of most frequent byte-pair using zero- frequency byte in the source data. This process is repeated for maximum m possible number of passes until no further compression is possi...
