To my knowledge this is the only(?) compression codec using Hopf-fibration quotient coding in any way. It&#x27;s lossy, guarantees fixed rate compression on any input, zero codebook (same as other vector quantizers), provable exact O(1) random access, and ships a fully deterministic compile-time provable format. Beats int-N quantization cleanly in all metrics, haven&#x27;t directly compared it to data-adaptive methods yet, but since they lie on a completely different functionality axis felt like there was no need. Had this idea for quite a while now, but never had…</p><p><a href="https://hackerpaper.kaipfister.de/p/2008.10728/">Paper and discussion history</a>. A mention is not an endorsement.</p>cs.IT
