TOPOLOGICAL DATA ANALYSIS

See what your data
actually looks like.

Pulsar is a topological data analysis engine that finds the real structure in high-dimensional data — not the shape your model assumes. Instead of betting on one clustering or embedding, it sweeps hundreds and keeps only the structure that survives all of them.

HOW IT WORKS

Stop picking the pretty embedding.

K-means, UMAP, DBSCAN — each forces your data into a shape it picked, then ships the prettiest result. Nudge one parameter and the clusters dissolve. Pulsar takes the opposite bet: it trusts only the structure that holds no matter how you look.

K-means says

“I see three groups. (Change k to six and none of this means anything anymore.)”

Pulsar says

“Here are the communities the data actually has. Ask for more resolution — the structure holds.”

Judging your data from one clustering is like judging a sculpture from one photo — the angle alone can make it look like a blob, a cross, or a face. Pulsar photographs it from hundreds of angles simultaneously (the multiverse sweep), keeps only what shows up in every shot, and fuses them into one reliable picture: the Cosmic Graph.

01 / Sweep

Build hundreds of representations across a grid of parameters — photograph the data from every angle, not one.

02 / Build

Construct a graph for each. Any single one can be lucky or misleading — so none gets to decide alone.

03 / Fuse

Accumulate the evidence into one Cosmic Graph. Only structure that persists across every view survives.

Structure that persists across 100 representations is structure you can trust.

It's built on the THEMA algorithm — peer-reviewed in Nature Energy.

SEE IT RUN

Pulsar recovered a landmark cardiology finding in 5 minutes.

Pulsar runs a full topological analysis of a public Myocardial Infarction dataset — live in the Gemini CLI through its open MCP integration. No labels, no clinical priors, no AHA guidelines.

1989 → 5 min

The nitrate contraindication in right-ventricular MI took decades and a 40-patient study to codify. Pulsar recovered it from raw, unlabeled data in a single session.

Zero medical priors

No labels, no clinical knowledge — just the geometry of a public dataset, mapped from scratch and handed to the model to interpret.

The Hidden Crash

It isolated a distinct cohort of seemingly low-risk patients who deteriorate catastrophically — a preload-dependent group that nitrates can tip into cardiogenic shock.

Runs entirely on the open-source engine and its MCP integration — nothing proprietary. Get it on GitHub
