ubpe 0.2.1

UBPE Tokenizer

UBPE Tokenizer

UBPE -- Universal Byte-Pair Encoding. Universal means that it works not only with strings, but with general sequences too.

The package provides Universal Byte-Pair Encoding tokenizers:

• UBPEClassic -- optimized version of classic BPE algorithm
• UBPE -- novel approach to BPE tokenization which allows you to choose between multiple different variants of encodings according to scores of tf-idf metric or something else; the most optimal encoding from this implementation was shorter than the encoding from classic implementation

Guides and theory

• Description of tokenizer fitting algorithms
• Description of encoding and decoding algorithms for classic and novel approaches

Installation

I am planning to deliver different implementations for the algorithm, so the package is divided into general import package (this one), and implementations (for now, Python native and Cython with C++20 backend). To install use:

pip install ubpe[native]

Or,

pip install ubpe[cython]

Bug reports

If you find a bug that occurs under certain circumstances in some tests, please report it.

Contribution

I am pretty sure, that it has not the most optimal native Python implementation and C++ backend, so feel free to propose optimizations and bug fixes.

It's planned to add Rust implementation with Python bindings (not to bite Hugging Face, just because).

P.S. if you are working at Hugging Face, you can write me and hire me. Please.
