Large Deviations for Markovian Graphon Processes and Associated Dynamical Systems on Networks
Shankar Bhamidi, Amarjit Budhiraja, Souvik Ray
We consider temporal models of rapidly evolving Markovian networks whose edge-formation and dissolution rates are determined by time-dependent spatial kernels. Equivalently, these…
Component Spectrum of Large Sparse Uniformly Random Magical Squares
Souvik Ray
In this paper, we shall try to deduce asymptotic behaviour of component spectrum of random magical squares with line sum , which can also be identifi…
Characterizing Logarithmic Bregman Functions
Souvik Ray, Subrata Pal, Sumit Kumar Kar +1
Minimum divergence procedures based on the density power divergence and the logarithmic density power divergence have been extremely popular and successful in generating inference…
On the stability of solutions to random optimization problems under small perturbations
Sourav Chatterjee, Souvik Ray
Consider the Euclidean traveling salesman problem with random points on the plane. Suppose that one of the points is shifted to a new random location. This gives us a new optim…
Random walk in slowly changing environments
Bryan Park, Souvik Ray
A Random Walk in Changing Environment (RWCE) is a weighted random walk on a locally finite, connected graph with random, time-dependent edge-weights. This includes self-interac…
Characterizing the Functional Density Power Divergence Class
Souvik Ray, Subrata Pal, Sumit Kumar Kar +1
Divergence measures have a long association with statistical inference, machine learning and information theory. The density power divergence and related measures have produced man…
