PhD Seminar • Algorithms and Complexity • Cheeger Inequalities for Directed Graphs and Hypergraphs using Reweighted Eigenvalues

Please note: This PhD seminar will take palce in M3 4206 and online.

Supervisor: Professor Lap Chi Lau

We derive Cheeger inequalities for directed graphs and hypergraphs using the reweighted eigenvalue approach that was recently developed for vertex expansion in undirected graphs. The goal is to develop a new spectral theory for directed graphs and an alternative spectral theory for hypergraphs.

RDF knowledge bases are now first-class citizens of the Web with over 100 billion RDF assertions in the 2022 WebDataCommons crawl. Developing explainable machine learning approaches tailored towards this data is hence a task of increasing importance.
