On the Optimization of Methods for Establishing Well-Connected Communities

Mohammad Dindoost, Oliver Alvarado Rodriguez, Bartosz Bryg +4

Community detection plays a central role in uncovering meso scale structures in networks. However, existing methods often suffer from disconnected or weakly connected clusters, und…

Dense Subgraph Clustering and a New Cluster Ensemble Method

The-Anh Vu-Le, João Alfredo Cardoso Lamy, Tomás Alessi +5

We propose DSC-Flow-Iter, a new community detection algorithm that is based on iterative extraction of dense subgraphs. Although DSC-Flow-Iter leaves many nodes unclustered, it is…

Using Stochastic Block Models for Community Detection: The issue of edge-connectivity

The-Anh Vu-Le, Minhyuk Park, Ian Chen +2

A relevant, sometimes overlooked, quality criterion for communities in graphs is that they should be well-connected in addition to being edge-dense. Prior work has shown that leadi…

An Agent-based Model of Citation Behavior

George Chacko, Minhyuk Park, Vikram Ramavarapu +3

Whether citations can be objectively and reliably used to measure productivity and scientific quality of articles and researchers can, and should, be vigorously questioned. However…

FastEnsemble: scalable ensemble clustering on large networks

Yasamin Tabatabaee, Eleanor Wedell, Minhyuk Park +1

Many community detection algorithms are inherently stochastic, leading to variations in their output depending on input parameters and random seeds. This variability makes the resu…

EC-SBM Synthetic Network Generator

The-Anh Vu-Le, Lahari Anne, George Chacko +1

Generating high-quality synthetic networks with realistic community structure is vital to effectively evaluate community detection algorithms. In this study, we propose a new synth…
