htm-monitor provides rare, actionable early warnings for critical systems. Unsupervised. Domain-agnostic. Validated against real historical events with known outcomes.
htm-monitor works on any system that produces continuous numeric data over time. The same unsupervised engine adapts to each domain.
Real-time anomaly detection for electrical grid infrastructure. Validated against ERCOT, CAISO, and NYISO with 6+ years of public data.
Early detection of patient deterioration from continuous vital signs using MIMIC-IV data. Same engine, different domain.
htm-monitor has been tested against real historical events with known outcomes. Here's what it found.

Early detection of patient deterioration from continuous vital signs
Applying htm-monitor to real ICU vital sign streams (heart rate, blood pressure, SpO2, respiratory rate) from the MIMIC-IV dataset to detect early signs of sepsis, cardiac arrest, and respiratory failure before traditional early warning scores trigger.
The engine is Hierarchical Temporal Memory — a biologically-inspired sequence-learning algorithm extended with a grouped-consensus decision layer.
Each signal model learns its temporal patterns continuously, adapting to drift without retraining. No fixed thresholds. No supervised labels required.
System alerts fire only when multiple independent signal models agree. This cross-group consensus layer dramatically reduces false positives.
Every alert is traceable to specific signal anomalies at specific timesteps. Per-model, per-group visibility lets operators understand exactly what triggered and why.
Runs single-process in Python. No GPU. No external API calls. Deploys on a $5/mo VPS or inside an air-gapped VM — operator's choice.
Most anomaly detection systems generate noise. htm-monitor is built for the opposite: say nothing until something genuinely matters, then say it early enough to act. Foresight is power.
We believe the same unsupervised temporal learning engine can serve any domain that produces continuous numeric data — power grids, patient monitors, industrial sensors, financial feeds. The pattern is universal: learn what normal looks like, and flag when reality departs from the learned envelope.
A system that cries wolf loses trust. htm-monitor is designed for rare, high-confidence alerts — not dashboard noise.
No labeled training data required. The system learns from the structure of normal operations and flags departures automatically.
Every alert is fully auditable, traceable to specific signals and timesteps. Operators can see exactly what the system sees.
The same engine works across power grids, patient monitoring, and beyond. If it's continuous numeric data over time, htm-monitor can learn it.
htm-monitor is developed and operated by DataGrip LLC. We're focused on making unsupervised temporal anomaly detection practical and accessible for critical infrastructure operators.
