Federated Learning Sensor Network

A privacy-preserving federated learning system for distributed temperature sensors that enables collaborative pattern detection while maintaining data privacy. The system handles multiple sensor types (factory, office, outdoor) with unique event patterns and real-time visualization of both sensor data and privacy metrics.

Challenge

Design a system that can learn from distributed sensor data without centralizing sensitive information, while detecting and adapting to complex patterns specific to different environments, maintaining privacy guarantees, and providing real-time analytics.

Solution

Implemented a federated learning architecture where sensors perform local pattern learning with neural networks, sharing only aggregated patterns while maintaining individual privacy scores. The system includes real-time visualization of temperature patterns, accuracy metrics, and privacy preservation levels.

Implementation

  • Developed local neural network models for pattern detection
  • Created environment-specific pattern generators for different sensor types
  • Implemented privacy scoring system with preservation metrics
  • Built comprehensive real-time visualization system
  • Integrated pattern library with event impact analysis
  • Created multi-layer analytics dashboard with GridSpec
