    Selected Challenges in ML Safety for Railway
    Neural networks (NN) have been introduced in safety-critical applications from autonomous driving to train inspection. I argue that to close the demo-to-product gap, we need scientifically-rooted engineering methods that can efficiently improve the quality of NN. In particular, I consider a structural approach (via GSN) to argue the quality of neural networks with NN-specific dependability metrics. A systematic analysis considering the quality of data collection, training, testing, and operation allows us to identify many unsolved research questions: (1) Solve the denominator/edge case problem with synthetic data, with quantifiable argumentation (2) Reach the performance target by combining classical methods and data-based methods in vision (3) Decide the threshold (for OoD or any kind) based on the risk appetite (societally accepted risk).
