Coherence Intelligence for Natural & Engineered Systems
HSAG develops measurement and inference methods that quantify phase‑locked structure across signals and fields. Our products transform spectral signatures into early‑warning and diagnostic intelligence for operational use.
Resonance. Coherence. Discovery.
Why Coherence?
Traditional guidance focuses on amplitudes (flux, CAPE, shear). STELLAR adds a complementary lens: phase‑coherent structure. PCI/BCS metrics quantify when variables remain phase‑locked, and when they begin to decohere—often hours before classical thresholds.
-
Early detection of instability windows
-
Quantified regime classification (stable ↔ convective ↔ mechanical)
-
Low‑overhead deployment, model‑agnostic outputs
Core Methods
HSAG libraries compute cross‑spectral metrics that expose coupling across scales.
-
Phase‑Coherence Index (PCI): stability of cross‑variable phase over frequency
-
Band‑Coherence Spectrum (BCS): coherent bands exceeding threshold with phase context
-
Harmonic Drift: detection of migrating or collapsing resonant peaks
Outputs stream as CSV/JSON or embed into dashboards and AI pipelines.
