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…
