Lab report: a symmetry selection rule for computation in phononic / quasicrystal MEMS reservoirs.

A PyTorch framework for training neural stochastic differential equations (SDEs) to model dynamical systems with both deterministic and stochastic components. This framework enables the learning of dynamical systems through a combination of neural networks representing drift and diffusion terms, with adversarial training. Docs ⬇️

Finite-element study of quasicrystal-perforated MEMS resonators and what their mode structure can (and cannot) compute as a physical reservoir. Includes the paper.

A nonvolatile memory cell made of gravity: a bit stored in which Lagrange island (L4/L5) a body librates in — written by orbit insertion, rewritten by a real flyby, and validated against Jupiter's real 148-year Trojan libration.

A package of simple reservoir computing tools

TopoCore is an experimental spatial execution architecture where programs are represented as traversable 2D layouts rather than linear instruction streams. Inspired by Befunge, semiotics, and semasiographic systems, it explores topology-driven control flow, direction-aware computation and non-linear execution 🕸️.
