This thesis addresses fleet-level consolidation of embedded machine learning models for accelerometer self-diagnostics in railway systems deployed on the COSAMIRA Edge platform. Each device currently learns the expected accelerometer behavior using speed and acceleration data and detects sensor faults through deviation from the learned model.

Such a system is used in large railway fleets where multiple trains of the same type operate under varying mechanical, environmental, and seasonal conditions. While per-device learning works, it does not gener
