Byte-Level Mutual Information Decays as a Power Law Across 5 Languages

How does mutual information between bytes decay with distance in natural language, and is this structure universal across languages with different scripts and morphology?

• Mutual information between bytes decays as a power law I(d) ~ d^(-alpha) in all 5 languages tested (0 out of 5 exponenti…
• 82-96% of prediction gain comes from the first 8 bytes of context. Conditional entropy drops from ~5 bits (unigram) to ~…
