Global Incident Early Warning Aggregator

The Global Incident Early Warning Aggregator is a sophisticated system designed to aggregate multi-source telemetry and detect anomaly patterns to facilitate early incident warning across various domains. This project stands at the intersection of data science and real-time monitoring, employing statistical methods to provide timely alerts across different signal types such as seismic, epidemiological, climate, and satellite data.

Overview

The system utilizes real-time anomaly detection and alerting mechanisms to analyze diverse signal inputs. Using statistical multi-model detection techniques, it identifies anomalous patterns and generates alerts accompanied by confidence intervals, ensuring improved decision-making capabilities.

Core Features

• Data Ingestion Pipelines: Enables data ingestion via HTTP APIs and streaming protocols (Kafka/NATS).
• Signal Normalization: Implements type-specific normalization scales for various data types, ensuring consistency in processing.
• Statistical Anomaly Detection: Leverages a multi-model ensemble approach for detecting anomalies using methods like Z-score, IQR, moving average, and rate of change.
• Alert Emission: Facilitates versioned and reproducible alert generation to maintain traceability and reliability.
• Confidence Interval Modeling: Provides statistical confidence bounds for all alerts, aiding in risk assessment.

API Functionality

POST /ingest

This endpoint ingests a signal for processing anomaly detection. The expected request format is as follows:

{  
  "source_id": "string",  
  "signal_type": "seismic | epidemiological | climate | satellite",  
  "timestamp": "iso8601",  
  "payload": {...}  
}  

The responses include information on processing status, detected anomalies, and generated alerts.

GET /alerts

Retrieve alerts with optional filtering parameters, allowing users to query based on severity, confidence, and time range.

GET /stats and GET /health

These endpoints provide valuable insights into system performance and health status, ensuring smooth operational management.

Robust Development Practices

All alerts are configured to include confidence bounds, ensuring that the system promotes reliability through versioning of model weights and reproducible alert generation. Key components of the project encompass the signal normalizer, anomaly detector, confidence engine, alert publisher, and ingestion pipeline for comprehensive processing.

Testing and Quality Assurance

Testing capabilities are built into the system, allowing for extensive validation of functionality and performance through a dedicated test suite.

By combining in-depth data analysis with robust statistical methodologies, this project offers a powerful tool for organizations needing to detect and respond to incidents across various fields. This is achieved while maintaining a high standard of reproducibility and reliability in alert generation.
