Thank you — the content had been flagged earlier but the issue has now been resolved. Everything is restored and functioning as expected. Please let me know if you encounter any further problems.
Unstable Singularity Detector is an open-source implementation of a Physics-Informed Neural Network (PINN) system that detects blow-up singularities in PDEs — like those found in fluid dynamics.
It’s inspired by the methodology in a recent DeepMind paper, but fully independently built from scratch. The system predicts instability thresholds (lambda values), trains PINNs in multiple stages, and reaches machine-level residuals (10⁻¹³) using a high-precision Gauss–Newton optimizer.
This new v1.4.1 release adds: - Multi-stage PINN orchestration with FSDP and Meta/K-FAC support - Rank-1 Hessian + EMA for memory-efficient Gauss–Newton optimization - Residual certificate generation (CI-ready) - CLI bridge to external CFD solver output (e.g., `.npz` files) - Docker/Gradio support for easier setup
No signups, no cloud dependencies — everything runs locally (CLI, Docker, or Gradio).

Would love feedback from folks working on scientific computing, PDE solvers, numerical methods, or ML-based verification. I’m around for questions.
