TLDR
An algorithm is described which gives excellent results when tested on both computer-generated and real-world networks and is much faster, typically thousands of times faster, than previous algorithms.
Abstract
Many networks display community structure--groups of vertices within which connections are dense but between which they are sparser--and sensitive computer algorithms have in recent years been developed for detecting this structure. These algorithms, however, are computationally demanding, which limits their application to small networks. Here we describe an algorithm which gives excellent results when tested on both computer-generated and real-world networks and is much faster, typically thousands of times faster, than previous algorithms. We give several example applications, including one to a collaboration network of more than 50,000 physicists.

Weighted Evolving Networks with Self-organized Communities

TL;DR: A new evolving model for weighted community-structured networks with the preferential mechanisms functioned in different levels according to community sizes and node strengths, with tunable exponents of ν ≥ 1, γ > 2, and α > 2 is proposed.

Feature Selection and Combination of Information in the Functional Brain Connectome for Discrimination of Mild Cognitive Impairment and Analyses of Altered Brain Patterns

TL;DR: The findings demonstrate that optimal feature selection and combination of all connectome features can achieve good performance in discriminating NCs from MCI subjects and contribute to the early clinical diagnosis of AD.

A Link-Based Similarity for Improving Community Detection Based on Label Propagation Algorithm

TL;DR: A new modified version of LPA is proposed to improve the stability and accuracy of the LPA by defining two concepts -nodes and link strength based on semi-local similarity-, while preserving its simplicity.

Clustering social networks using ant colony optimization

TL;DR: This paper demonstrates that ACO based approach to community detection results in a significant improvement in modularity values as compared to existing heuristics in the literature when tested on real and synthetic data sets.

Exploring the structure of misconceptions in the Force Concept Inventory with modified module analysis

TL;DR: In this paper, modified module analysis is applied to the Force Concept Inventory to understand the structure of the incorrect answers, and the correct answers are found to be more accurate than incorrect answers.

Statistical mechanics of complex networks

TL;DR: In this paper, a simple model based on the power-law degree distribution of real networks was proposed, which was able to reproduce the power law degree distribution in real networks and to capture the evolution of networks, not just their static topology.

Community structure in social and biological networks

TL;DR: This article proposes a method for detecting communities, built around the idea of using centrality indices to find community boundaries, and tests it on computer-generated and real-world graphs whose community structure is already known and finds that the method detects this known structure with high sensitivity and reliability.

Finding and evaluating community structure in networks.

TL;DR: It is demonstrated that the algorithms proposed are highly effective at discovering community structure in both computer-generated and real-world network data, and can be used to shed light on the sometimes dauntingly complex structure of networked systems.
