Self-Supervised Hyperboloid Representations from Logical Queries over Knowledge Graphs

2021

Knowledge Graphs (KGs) are ubiquitous structures for information storage in several real-world applications such as web search, e-commerce, social networks, and biology. Querying KGs remains a foundational and challenging problem due to their size and …

Task-Agnostic Graph Explanations

2022 · arXiv (Cornell University)

Graph Neural Networks (GNNs) have emerged as powerful tools to encode graph-structured data. Due to their broad applications, there is an increasing need to develop tools to explain how GNNs make decisions given graph-structured data. …
