Mini toolsDefinition
An unsupervised text tokenizer that learns to break text into subword units. It treats the input as a sequence of Unicode characters and requires no pre-tokenization.
Detailed Explanation
SentencePiece implements subword tokenization algorithms like BPE and unigram language model tokenization. It processes raw text as a sequence of Unicode characters making it language-agnostic and eliminating the need for language-specific pre-processing. The tokenizer learns directly from raw text and can handle any language without modification.
