On the lack of monotonicity of Newton-Hewer updates for Riccati equations
Mohammad Akbari, Bahman Gharesifard, Tamas Linder
We provide a set of counterexamples for the monotonicity of the Newton-Hewer method for solving the discrete-time algebraic Riccati equation in dynamic settings, drawing a contrast…
A Finite Memory Interacting Pólya Contagion Network and its Approximating Dynamical Systems
Somya Singh, Fady Alajaji, Bahman Gharesifard
We introduce a new model for contagion spread using a network of interacting finite memory two-color Pólya urns, which we refer to as the finite memory interacting Pólya contagion…
Initialization and Curing Policies for Polya Contagion Networks
Greg Harrington, Fady Alajaji, Bahman Gharesifard
This paper investigates optimization policies for resource distribution in network epidemics using a model that derives from the classical Polya process. The basic mechanics of thi…
Universal Approximation Power of Deep Residual Neural Networks via Nonlinear Control Theory
Paulo Tabuada, Bahman Gharesifard
In this paper, we explain the universal approximation capabilities of deep residual neural networks through geometric nonlinear control. Inspired by recent work establishing links…
Anytime Proximity Moving Horizon Estimation: Stability and Regret
Meriem Gharbi, Bahman Gharesifard, Christian Ebenbauer
In this paper, we address the efficient implementation of moving horizon state estimation of constrained discrete-time linear systems. We propose a novel iteration scheme which emp…
Least th-Order and Rényi Generative Adversarial Networks
Himesh Bhatia, William Paul, Fady Alajaji +2
We investigate the use of parametrized families of information-theoretic measures to generalize the loss functions of generative adversarial networks (GANs) with the objective of i…
Rate of Convergence for Distributed Optimization with Uncertain Communications
Pouya Rezaeinia, Bahman Gharesifard
We consider the distributed optimization problem for the sum of convex functions where the underlying communications network connecting agents at each time is drawn at random from…
The trouble with imaginary eigenvalues. Optimal control, controllability, frequency response
Bahman Gharesifard, Andrew D. Lewis
We investigate a few problems in the theory of linear time-invariant systems that arise when the open-loop system possesses imaginary eigenvalues. The problems are: (1) the infinit…
