Show HN: Unstable Singularity Detector update 1.4.1

Hi HN, I'm the author of this project. 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). GitHub: https://github.com/Flamehaven/unstable-singularity-detector Paper inspiration: https://arxiv.org/abs/2509.14185 Would love feedback from folks working on scientific computing, PDE solvers, numerical methods, or ML-based verification. I’m around for questions.

Show HN: Unstable Singularity Detector

### Why I built - Earlier this year, DeepMind published groundbreaking work on detecting unstable singularities in fluid dynamics—one of the deepest open problems in mathematical physics (arXiv:2509.14185). - The challenge? No public code. - Extreme numerical precision requirements. - Complex multi-stage training. This makes independent verification nearly impossible. - So I built an open-source re-implementation to bridge that gap. --- ### What It Does Detects finite-time blow-ups in PDEs using Physics-Informed Neural Networks: - Lambda prediction formulas (<1% error vs. published methodology) - Automated parameter discovery via funnel inference - High-precision Gauss-Newton optimization (residuals to 10⁻¹³) - Multi-stage training with configurable precision targets Think: Making century-old fluid dynamics problems tractable with modern

ML. --- ### Who This Is For - Researchers studying singularities in PDEs - Practitioners working with PINNs - Anyone frustrated by non-reproducible ML papers - Students learning scientific machine learning --- ### Built For Reproducibility - 119 comprehensive tests (all passing) - GPU-accelerated with PyTorch + CUDA - Automated validation CI/CD - Professional documentation + limitations clearly stated - Not just "research code"—designed to actually work in other people's hands. --- ### Current Implementation Status - Lambda prediction formulas (formula-based validation) - Funnel inference (secant method) - Enhanced Gauss-Newton optimizer (test problem verified) - PINN solver framework - Multi-stage training (framework complete, full validation pending) - Full 3D Navier-Stokes solver (future work) - Transparency matters: This shows exactly what works today vs. what's roadmap. --- ### Links GitHub: https://github.com/Flamehaven/unstable-singularity-detector Paper: https://arxiv.org/abs/2509.14185 Documentation: README includes limitations, validation methodology, troubleshooting --- ### Important Disclaimer This is an independent re-implementation inspired by DeepMind's published methodology. It is NOT affiliated with, endorsed by, or in collaboration with DeepMind. Results are validated against published formulas, not direct comparison with DeepMind's unpublished experimental data. --- If you've ever wished "I wish I could just run their code," this is for you. Contributions, issues, and feedback welcome. Let's make frontier research more accessible together.
