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…
