A private research lab working at the edge of data compression, neuromorphic
vision and computational geometry. One recurring principle, studied across
many domains: the shape of the part already knows the shape of the whole.
Every project here starts from a single observation —
that in many systems the local already contains the global.
Compression, vision, signal, form. When you find the right axis of
symmetry, the data stops being data. It becomes pattern.
And patterns carry themselves.
One is live. Four on the way.

01 · CodecLive
The Codec
codec.mirrorfractal.com
A lossless codec for neuromorphic event-camera streams. Treats sparse
asynchronous events as a self-referential structure, and compresses
them accordingly. Python wheels and a WebAssembly browser demo are
published; a preprint is archived on Zenodo. US provisional filed.

02 · FormatSoon
.frac
frac.mirrorfractal.com
A spatial container format for drawings, diagrams and layered geometric
data. Progressive delivery, browser-native viewer, small footprint. Built
for architecture, PCB, medical imaging — anything hierarchical that
needs to travel through a narrow pipe.

03 · LLMSoon
The LLM
llm.mirrorfractal.com
A compression library for neural-network weights. Treats each parameter
group as a branching decision tree to squeeze large language models
into places they currently don't fit — smaller devices, narrower memory,
tighter latency budgets — without the usual accuracy cliff.

04 · StreamSoon
The Stream
stream.mirrorfractal.com
A transport layer tuned for progressive, quality-aware content delivery.
Content arrives in meaningful layers — coarse first, refined later — so
that every byte already says something useful about the whole. Target
workloads: live medical imaging, engineering drawings, map tiles.

05 · FuzzySoon
The Fuzzy
fuzzy.mirrorfractal.com
An approximate retrieval engine for noisy, partial or imprecise queries.
Same recursive idea as the rest of the lab — build the lookup path out
of self-similar branches so that imperfect input still lands close to
the right neighbourhood.

02 / Research
Archived, reviewed, patent pending.
We publish. Preprints land on open archives so that the work is dated,
readable, and independently verifiable. Binary distributions ship through
the usual package registries. A provisional patent is on file for the
method underlying the codec; commercial licensing is available directly.
Quarterly note when a new project ships. No noise, no marketing.
Just the work.
"Every structure carries a smaller version of itself.
We build the tools that listen for it."

About · MMXXVI
The shape of the part already knows the shape of the whole.
A private research lab exploring one recurring principle — self-similarity —
across compression, vision, and computational geometry. One thesis. Many
experiments. A slow, deliberate build.
01 · Thesis
Recursion over compression.
We don't chase ratios. We look for the axis along which data folds
onto itself — and let the folding do the work. Ratios are a
consequence, not a target.
02 · Method
Slow, deliberate.
Experiments first, tools second, products third. Nothing ships until
a bit-exact round-trip passes. Nothing becomes a product until it
has at least one real user who pays for it.
03 · Stance
Open enough. Protected enough.
Preprints public, binaries shipped, patents filed. The internals
that matter stay internal. The parts that help people evaluate the
work go out into the open.
04 · Scope
Many domains, one idea.
Compression. Neuromorphic vision. Sparse geometry. Neural-network
weights. Approximate search. Surface level they look unrelated;
underneath there is only one pattern.
05 · Craft
The math must ship.
A theorem is worth nothing until it is code someone can run. A
benchmark is worth nothing until it is reproducible on a laptop.
Theory ships as software or it doesn't ship.
06 · Ethic
Verifiable by anyone.
Every claim we publish comes with a way to check it. No trust-us
numbers. Every headline benchmark is replayable against public
data — or it is not a benchmark, it is marketing.

Aleksei Solonskii
Founder · Research
Independent researcher. Works on compression, neuromorphic sensors,
and applied geometry. Autónomo in Valencia, Spain.
Mirror Fractal is, for now, deliberately a one-person operation. The
only way to hold a single idea steady across many domains is to keep
the organisation small enough that the idea doesn't blur.
We collaborate with other researchers, with engineering partners, and
with end users who are willing to try things that aren't yet on
anyone's roadmap. We don't scale headcount. We scale what we know.
If you'd like to work on a problem together — industrial partners,
PhD candidates looking for a weird co-author, or anyone with
neuromorphic data they can't compress — the door is open.
US Provisional No. 64/034,974. Covers the method underlying the
codec. PCT filing will follow within the 12-month priority window.
