Biological functions are carried out by groups of interacting molecules, cells or tissues, known as communities. Membership in these communities may overlap when biological components are involved in multiple functions. However, traditional clustering methods detect non-overlapping communities. These detected communities … Continue reading
An important problem in the analysis of network data is the detection of groups of densely interconnected nodes also called modules or communities. Community structure reveals functions and organizations of networks. Currently used algorithms for community detection in large-scale real-world … Continue reading
The discovery of the community structure of real-world networks is still an open problem. Many methods have been proposed to shed light on this problem, and most of these have focused on discovering node community. However, link community is also … Continue reading
Detecting communities or clusters in a real-world, networked system is of considerable interest in various fields such as sociology, biology, physics, engineering science, and interdisciplinary subjects, with significant efforts devoted in recent years. Many existing algorithms are only designed to … Continue reading
How does network structure affect diffusion? Recent studies suggest that the answer depends on the type of contagion. Complex contagions, unlike infectious diseases (simple contagions), are affected by social reinforcement and homophily. Hence, the spread within highly clustered communities is … Continue reading
Our overall interest here, is in those kinds of things that people can only do together that they cannot possibly do apart, in isolation from each other. Our interests resonate with the themes and topics expressed in the epigraph quotes … Continue reading
Lifelong learning plays a crucial role in society today as jobs, and the skills they require, are changing. Recent technological and social developments in online settings have the potential to support lifelong learning in new ways. Online collaborative spaces can … Continue reading
