SentencePiece
An unsupervised text tokenizer and detokenizer for neural network-based text generation systems with subword units.
What is SentencePiece?
SentencePiece is an unsupervised text tokenizer and detokenizer primarily for neural network-based text generation systems. It implements subword units like byte-pair-encoding (BPE) and unigram language models to handle open vocabulary problems, allowing direct training from raw sentences without language-specific preprocessing.
Researchers and engineers working on neural machine translation, text generation models, and NLP systems requiring efficient subword tokenization.
It offers a fast, language-independent, and reversible tokenization method with support for subword regularization, enabling robust and accurate end-to-end text processing without external tokenizers.
