UnverifiedThe optimization objectives of the mainstream tokenization algorithms BPE and Unigram are essentially both compression: minimizing the corpus encoding length under a limited vocabulary.79% similarUnverifiedUnigram 模型由 SentencePiece 库实现，从大词表出发逐步剔除对整体似然贡献最小的子词来缩减词表77% similarVerifiedModern LLMs generally use BPE (Byte Pair Encoding) or WordPiece algorithms for tokenization.77% similarVerifiedA token is the smallest semantic unit segmented by subword tokenization algorithms such as BPE, and is not simply equivalent to a single character or word.77% similarVerifiedThe byte pair encoding (BPE) or WordPiece algorithms widely used in modern large models are essentially data-driven morphological segmentation methods.75% similar
