In-n-Out: Calibrating Graph Neural Networks for Link Prediction


title_rewrite


Graph neural networks (GNNs) are often miscalibrated for link prediction tasks, exhibiting a mixed behavior of overconfidence in negative predictions and underconfidence in positive ones. The proposed method, IN-N-OUT, effectively calibrates GNNs for link prediction tasks.
