Statistical Anomaly Detection & Explainable Risk Engine
Multi-transducer sensor fusion, rolling Z-score persistence analysis, and Pearson inter-station correlation.
DEMO SYNTHETICModel: EWMA + Robust Z-Score (v2.1)Normal[L0]
DGMS Safety-Critical Decision Support Standard: This platform performs statistical anomaly detection and evidence-based risk assessment. It detects abnormal rates of change, multi-station persistence, and cross-modality correlation. It does not claim deterministic collapse prediction.

Anomaly Detection Model Configuration & Rejection Filters
| Model Component | Algorithm | Sample Window | Rejection Filter | Regulatory Reference |
|---|---|---|---|---|
| Baseline Smoothing | Exponentially Weighted Moving Average (EWMA) | α = 0.20 (15-sample window) | High-frequency machinery vibration filter | DGMS TC 4/2017 |
| Outlier Scoring | Median Absolute Deviation (Robust Z-Score) | N = 50 samples rolling | Rejects single-point transient spikes (|z| < 2.5) | CMPDI Technical Standard |
| Spatial Cross-Check | Pearson Bivariate Inter-Node Correlation | Adjacent nodes in extraction panel | Single-node failure requires second-node corroboration | DGMS CMR Reg 112 |
