SMGRL: Scalable Multi-resolution Graph Representation Learning

1 code implementation29 Jan 2022 Reza Namazi, Elahe Ghalebi, Sinead Williamson, Hamidreza Mahyar

The resulting multi-resolution embeddings can be aggregated to yield high-quality node embeddings that capture both long- and short-range dependencies.

On Evaluation Metrics for Graph Generative Models

1 code implementation ICLR 2022 Rylee Thompson, Boris Knyazev, Elahe Ghalebi, Jungtaek Kim, Graham W. Taylor

While we focus on applying these metrics to GGM evaluation, in practice this enables the ability to easily compute the dissimilarity between any two sets of graphs regardless of domain.

Building LEGO Using Deep Generative Models of Graphs

1 code implementation21 Dec 2020 Rylee Thompson, Elahe Ghalebi, Terrance DeVries, Graham W. Taylor

Generative models are now used to create a variety of high-quality digital artifacts.

A Nonparametric Bayesian Model for Sparse Dynamic Multigraphs

no code implementations11 Oct 2019 Elahe Ghalebi, Hamidreza Mahyar, Radu Grosu, Graham W. Taylor, Sinead A. Williamson

As the availability and importance of temporal interaction data--such as email communication--increases, it becomes increasingly important to understand the underlying structure that underpins these interactions.

Sequential Edge Clustering in Temporal Multigraphs

no code implementations28 May 2019 Elahe Ghalebi, Hamidreza Mahyar, Radu Grosu, Graham W. Taylor, Sinead A. Williamson

Interaction graphs, such as those recording emails between individuals or transactions between institutions, tend to be sparse yet structured, and often grow in an unbounded manner.

Dynamic Network Model from Partial Observations

no code implementations NeurIPS 2018 Elahe Ghalebi, Baharan Mirzasoleiman, Radu Grosu, Jure Leskovec

We propose a novel framework for providing a non-parametric dynamic network model--based on a mixture of coupled hierarchical Dirichlet processes-- based on data capturing cascade node infection times.
