Research and infrastructure for personalized intelligence — self-hosted AI systems you own, and the quantum-algorithms work behind them.
Maintained by Yury Chernyak. Most of the constellation is private; what is public is listed below.
hbar.science-vqe-regularization Does penalizing parameter magnitude help a Variational Quantum Eigensolver escape local minima? Over 25 random starts per λ on H₂, the fraction of runs trapped in a local minimum falls from 20% to 4%. Every Hamiltonian is validated against exact diagonalization, and the headline figure regenerates with one command. Python, Qiskit, MIT.
hbar.science-hopso Harmonic Oscillator based Particle Swarm Optimization (arXiv:2410.08043), where each particle is a damped harmonic oscillator about an attractor rather than a velocity update rule. Reference implementation, a periodic-parameter variant for circuit angles, and the distributed MPI/SLURM version used for cluster runs. MIT.
brainfoundry-nous A self-hosted sovereign AI brain: persistent memory, RAG, a governance kernel, and federation. Docker Compose, AGPL-3.0.
permitd Governed tool execution for agent loops — propose → permit → approve → execute → audit. Fail-closed, zero dependencies.
Small single-purpose applications that install into a brain and work over your own corpus. All AGPL-3.0.
| app | what it does |
|---|---|
| science-experiment | Five-field experiment records: hypothesis, prediction, method, result, critique |
| thread-consolidator | Paste a transcript; your brain proposes memory entries for you to approve |
| daybook | Twice a day your brain asks you something it actually knows to ask |
| self-portrait | Reads how your mind works, from your own corpus |
| oracle | Delphi-style answers drawn from your corpus. For reflection, not divination |
| mirror | Append-only outside-view notes on how you work |
| poker-journal | Hand histories, post-session reflection, grounded questions |
A set of hbar-health-* repositories: narrow, self-contained demonstrations of clinic
workflows built on the brain architecture — discharge letters, medication reconciliation,
billing, prescriptions, protocol capture.
