Sequential Stratified Regeneration: MCMC for Large State Spaces with an Application to Subgraph Count Estimation

1 code implementation7 Dec 2020 Carlos H. C. Teixeira, Mayank Kakodkar, Vinícius Dias, Wagner Meira Jr., Bruno Ribeiro

This work considers the general task of estimating the sum of a bounded function over the edges of a graph, given neighborhood query access and where access to the entire network is prohibitively expensive.

Unsupervised Joint k-node Graph Representations with Compositional Energy-Based Models

no code implementations NeurIPS 2020 Leonardo Cotta, Carlos H. C. Teixeira, Ananthram Swami, Bruno Ribeiro

Existing Graph Neural Network (GNN) methods that learn inductive unsupervised graph representations focus on learning node and edge representations by predicting observed edges in the graph.

Graph Pattern Mining and Learning through User-defined Relations (Extended Version)

1 code implementation14 Sep 2018 Carlos H. C. Teixeira, Leonardo Cotta, Bruno Ribeiro, Wagner Meira Jr

In this work we propose R-GPM, a parallel computing framework for graph pattern mining (GPM) through a user-defined subgraph relation.

Arabesque: A System for Distributed Graph Mining - Extended version

no code implementations14 Oct 2015 Carlos H. C. Teixeira, Alexandre J. Fonseca, Marco Serafini, Georgos Siganos, Mohammed J. Zaki, Ashraf Aboulnaga

However, these platforms do not represent a good match for distributed graph mining problems, as for example finding frequent subgraphs in a graph.
