Strictly proper scoring rules for node selection tasks on graphs
Lorenz Hilfiker, Nathan Cincera Brack, Martin Sterchi
In node selection tasks, the goal is to identify a single unknown target node in a graph. We consider probabilistic supervised node selection, where the estimator outputs a probabi…

Graph Neural Networks for Source Detection: A Review and Benchmark Study
Martin Sterchi, Nathan Brack, Lorenz Hilfiker
The source detection problem arises when an epidemic process unfolds over a contact network, and the objective is to identify its point of origin, i.e., the source node. Research o…
