A Graph Is More Than Its Nodes: Towards Structured Uncertainty-Aware Learning on Graphs

1 code implementation27 Oct 2022 Hans Hao-Hsun Hsu, Yuesong Shen, Daniel Cremers

Current graph neural networks (GNNs) that tackle node classification on graphs tend to only focus on nodewise scores and are solely evaluated by nodewise metrics.

What Makes Graph Neural Networks Miscalibrated?

1 code implementation12 Oct 2022 Hans Hao-Hsun Hsu, Yuesong Shen, Christian Tomani, Daniel Cremers

Furthermore, based on the insights from this study, we design a novel calibration method named Graph Attention Temperature Scaling (GATS), which is tailored for calibrating graph neural networks.

Automated Antenna Testing Using Encoder-Decoder-based Anomaly Detection

no code implementations27 Nov 2021 Hans Hao-Hsun Hsu, Jiawen Xu, Ravi Sama, Matthias Kovatsch

A contour-based anomaly detector can then map the reconstruction error matrix to an anomaly score to identify faulty antenna arrays and increase the classification F-measure (F-M) by up to 46%.
