Traffic scenarios and situations that are especially critical and/or occur only very rarely in the real world (i.e. anomalies) are of particular interest for the development and verification of autonomous vehicles. An essential part of my research is to extract such scenarios automatically from data sets as a first step and generate them synthetically as a next step, using deep learning methods on graph-structured data. One direction towards finding edge case scenarios in large-scale datasets is to apply concepts of anomaly detection. Specifically, as traffic scenarios are modeled as heterogeneous, spatio-temporal graphs in our research, the problem boils down to exploring and applying graph anomaly detection to especially large and complex scenario graphs.
