Uncertainty Propagation in Node Classification

2022 · 2022 IEEE International Conference on Data Mining (ICDM)

Quantifying predictive uncertainty of neural networks has recently attracted increasing attention. In this work, we focus on measuring uncertainty of graph neural networks (GNNs) for the task of node classification. Most existing GNNs model message …

Generating and Evaluating Plausible Explanations for Knowledge Graph Completion

2024

Explanations for AI should aid human users, yet this ultimate goal remains under-explored.This paper aims to bridge this gap by investigating the specific explanatory needs of human users in the context of Knowledge Graph Completion …
