StateSMix: Online Lossless Compression via Mamba State Space Models and Sparse N-gram Context Mixing
Roberto Tacconelli
We present StateSMix, a fully self-contained lossless compressor that couples an online-trained Mamba-style State Space Model (SSM) with sparse n-gram context mixing and arithmetic…
Aperiodic Structures Never Collapse: Fibonacci Hierarchies for Lossless Compression
Roberto Tacconelli
We study whether an aperiodic hierarchy can provide a structural advantage for lossless compression over periodic alternatives. We show that Fibonacci quasicrystal tilings avoid th…
Micro-Diffusion Compression - Binary Tree Tweedie Denoising for Online Probability Estimation
Roberto Tacconelli
We present Midicoth, a lossless compression system that introduces a micro-diffusion denoising layer for improving probability estimates produced by adaptive statistical models. In…
Nacrith: Neural Lossless Compression via Ensemble Context Modeling and High-Precision CDF Coding
Roberto Tacconelli
We present Nacrith, a lossless compression system that combines a 135M-parameter transformer language model (SmolLM2-135M) with an ensemble of lightweight online predictors and a 3…
