Random graph models for directed acyclic networks (2009)
Karrer, Brian, Newman, M. E. J.
We study random graph models for directed acyclic graphs, an important class of networks that includes citation networks, food webs, and feed-forward neural networks among others. We propose two...
Random acyclic networks (2009)
Karrer, Brian, Newman, M. E. J.
Directed acyclic graphs are a fundamental class of networks that includes citation networks, food webs, and family trees, among others. Here we define a random graph model for directed acyclic graphs...
Preservation of network Degree Distributions from non-uniform failures (2007)
Karrer, Brian, Ghoshal, Gourab
There has been a considerable amount of interest in recent years on the robustness of networks to failures. Many previous studies have concentrated on the effects of node and edge removals on the...
Robustness of community structure in networks (2007)
Karrer, Brian, Levina, Elizaveta, Newman, M. E. J.
The discovery of community structure is a common challenge in the analysis of network data. Many methods have been proposed for finding community structure, but few have been proposed for determining...
