Generating Similar Graphs From Spherical Features
Generating Similar Graphs Spherical Features exponential random graph model
2011/6/21
We propose a novel model for generating graphs similar to a given example graph.
Unlike standard approaches that compute features of graphs in Euclidean space, our
approach obtains features on a sur...

2009/9/22
A distribution of an a-spherical random vector is
shown to be uniquely determined by a distribution of quotients
We define a Fractional Brownian Motion indexed by a sphere, or more generally by a compact rank one symmetric space, and prove that it exists if, and only if, 0< H leq 1/2. We then prove that Fraction...

Several matrix variate hypergeometric type distributions are derived. The compound
distributions of left-spherical matrix variate elliptical distributions and inverted
hypergeometric type distributi...
