Network Signatures from Image Representation of Adjacency Matrices: Deep/Transfer Learning for Subgraph Classification
Kshiteesh Hegde, Malik Magdon-Ismail, Ram Ramanathan +1
We propose a novel subgraph image representation for classification of network fragments with the targets being their parent networks. The graph image representation is based on 2D…
An efficient alternative to Ollivier-Ricci curvature based on the Jaccard metric
Siddharth Pal, Feng Yu, Terrence J. Moore +3
We study Ollivier-Ricci curvature, a discrete version of Ricci curvature, which has gained popularity over the past several years and has found applications in diverse fields. Howe…
Generative Models for Global Collaboration Relationships
Ertugrul N. Ciftcioglu, Ram Ramanathan, Prithwish Basu
When individuals interact with each other and meaningfully contribute toward a common goal, it results in a collaboration, as can be seen in many walks of life such as scientific r…
Channel Assignment in Dense MC-MR Wireless Networks: Scaling Laws and Algorithms
Rahul Urgaonkar, Ram Ramanathan, Jason Redi +1
We investigate optimal channel assignment algorithms that maximize per node throughput in dense multichannel multi-radio (MC-MR) wireless networks. Specifically, we consider an MC-…
Dynamic Shortest Path Algorithms for Hypergraphs
Jianhang Gao, Qing Zhao, Wei Ren +3
A hypergraph is a set V of vertices and a set of non-empty subsets of V, called hyperedges. Unlike graphs, hypergraphs can capture higher-order interactions in social and communica…
Modeling and Analysis of Time-Varying Graphs
Prithwish Basu, Amotz Bar-Noy, Ram Ramanathan +1
We live in a world increasingly dominated by networks -- communications, social, information, biological etc. A central attribute of many of these networks is that they are dynamic…
