Clear implementation of arithmetic coding for educational purposes in Java, Python, C++.

Building better compression together

The Minimal LZMA (minlzma) project aims to provide a minimalistic, cross-platform, highly commented, standards-compliant C library (minlzlib) for decompressing LZMA2-encapsulated compressed data in LZMA format within an XZ container, as can be generated with Python 3.6, 7-zip, and xzutils

YAECL: Yet Another Entropy Coding Library for Neural Compression Research, with Arithmetic Coding and Asymmetric Numeral Systems support

This project is being developed as part of a Master's degree research sponsored by Brazil's CNPQ. It's goal is to design a hardware architecture to accelerate the AV1 arithmetic encoder.

An arithmetic coder for Rust.

LLMA = LLM + Arithmetic coder, which use LLM to do insane text data compression. LLMA=大模型+算术编码，它能使用LLM对文本数据进行暴力的压缩，达到极高的压缩率。

Arithmetic coding library with statistical models like PPM and Context mixing (demonstrating core principles of probabilistic inference, ensemble learning in AI)

Nacrith — Lossless text compression via ensemble neural arithmetic coding. Combines SmolLM2-135M language model with context mixing, adaptive prediction, and high-precision CDF coding. 3.1x better than gzip, and outperforming CMIX, ts_zip, LLMZip and FineZip. Fully lossless. GPU accelerated.
