Lossless Compression Python Packages

zxc-compress

Asymmetric lossless compression built for ultra-fast decode. 40%+ faster than LZ4 on ARM64, with better ratios. C library, write-once/read-many.

bigsmall

Lossless AI model compression - ~34% smaller with bit-identical weights; the autopilot profiles your machine, picks the highest fidelity that runs, and streams models bigger than your RAM.

mfc-codec

Mirror Fractal Codec — lossless compression for neuromorphic event camera data

zpe-iot

ZPE-IoT V0.0: DETERMINISTIC IOT SENSOR CODEC: 1D Time-Series | Chemosense | 17x Mean Compression | Rust Core | PyO3 Native | Edge-Deployable

zpe-xr

Smaller, faster, less accurate VR hand-frame codec. The float16+zlib comparator still wins on fidelity (gate 0/5). ContactPose evaluation lane; PyPI v0.3.1.

zpe-neuro

Deterministic spike-event extraction codec for electrophysiology signals; Python; Gate C/D PASS on bounded DANDI 000034

zpe-mocap

ZPE-Mocap V0.0: DETERMINISTIC MOTION CAPTURE CODEC: Joint Angles | Positional Fidelity | Search Ranking | Sub-ms Query | Skeletal Transport

zpe-ink

Python .zpink digital-ink codec — bit-exact roundtrip on UJI, CROHME, DigiLeTs (Hausdorff = 0.0 px). PyPI: zpe-ink v0.1.1.

zpe-imc-kernel

Optional native Rust kernel for zpe-multimodal stream scan and validation paths

zpe-music

Canonical symbolic-score codec with a bounded note-local expression refinement

zpe-smell

ZPE-Smell V0.0: Surrogate-receptor odor codec on a fixed 35-episode benchmark | Spearman 0.9996 | 0% mixture collision | Empirical olfactory perception out of scope

zpe-mental

Tunnel, spiral, lattice, cobweb — byte-exact codec on the bounded four-form corpus. Rust-native fast path with a Python reference. Not a cognition or clinical claim.

zpe-touch

ZPE-Touch V0.0: DETERMINISTIC TOUCH STREAM CODEC: Contact Geometry | Thermal | Vibrotactile | Proprioceptive Branch Isolation | Rust Core
