Trains and trams all around the world are equipped with Televic Rail solutions, from New Zealand to Canada, from China to the United States, from India to Belgium, England and France.

Your role:

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 generalize well across the fleet and may be sensitive to train-specific dynamics or temperature effects.

The objective of this thesis/internship is to design a method to collect learned models from selected devices, normalize and aggregate them into a single robust fleet-level model that remains stable despite inter-train disparities and seasonal variations.

Main challenges include:

- Robust model aggregation under heterogeneous operating conditions

- Outlier detection and rejection

- Ensuring insensitivity to mechanical and environmental variability

- Defining objective criteria to validate that local learning converged successfully

- Extending both the learning and inference phases to improve robustness and early fault detection

- The outcome will be a scalable fleet-intelligent framework for reliable embedded sensor health monitoring.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
