Theoretical Analysis of Active Contours on Graphs
Christos Sakaridis, Kimon Drakopoulos, Petros Maragos
Active contour models based on partial differential equations have proved successful in image segmentation, yet the study of their geometric formulation on arbitrary geometric grap…
A lower bound on the performance of dynamic curing policies for epidemics on graphs
Kimon Drakopoulos, Asuman Ozdaglar, John N. Tsitsiklis
We consider an SIS-type epidemic process that evolves on a known graph. We assume that a fixed curing budget can be allocated at each instant to the nodes of the graph, towards the…
When is a network epidemic hard to eliminate?
Kimon Drakopoulos, Asuman Ozdaglar, John N. Tsitsiklis
We consider the propagation of a contagion process (epidemic) on a network and study the problem of dynamically allocating a fixed curing budget to the nodes of the graph, at each…
An efficient curing policy for epidemics on graphs
Kimon Drakopoulos, Asuman Ozdaglar, John N. Tsitsiklis
We provide a dynamic policy for the rapid containment of a contagion process modeled as an SIS epidemic on a bounded degree undirected graph with n nodes. We show that if the budge…
On Learning with Finite Memory
Kimon Drakopoulos, Asuman Ozdaglar, John Tsitsiklis
We consider an infinite collection of agents who make decisions, sequentially, about an unknown underlying binary state of the world. Each agent, prior to making a decision, receiv…
