Using Graphlet Spectrograms for Temporal Pattern Analysis of Virus-Research Collaboration Networks
Dimitris Floros, Tiancheng Liu, Nikos Pitsianis +1
We introduce a new method for temporal pattern analysis of scientific collaboration networks. We investigate in particular virus research activities through five epidemic or pandem…
Fast Graphlet Transform of Sparse Graphs
Dimitris Floros, Nikos Pitsianis, Xiaobai Sun
We introduce the computational problem of graphlet transform of a sparse large graph. Graphlets are fundamental topology elements of all graphs/networks. They can be used as coding…
Spaceland Embedding of Sparse Stochastic Graphs
Nikos Pitsianis, Alexandros-Stavros Iliopoulos, Dimitris Floros +1
We introduce a nonlinear method for directly embedding large, sparse, stochastic graphs into low-dimensional spaces, without requiring vertex features to reside in, or be transform…
Rapid Near-Neighbor Interaction of High-dimensional Data via Hierarchical Clustering
Nikos Pitsianis, Dimitris Floros, Alexandros-Stavros Iliopoulos +3
Calculation of near-neighbor interactions among high dimensional, irregularly distributed data points is a fundamental task to many graph-based or kernel-based machine learning alg…
