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…

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…
