Centralized Versus Decentralized Optimization of Distributed Stochastic Differential Decision Systems with Different Information Structures-Part I: A General Theory
(2017)Decentralized optimization of distributed stochastic dynamical systems with two or more controls of the decision makers (DMs) has been an active area of research for over half a century. Although, such decentralized ...

Centralized Versus Decentralized Optimization of Distributed Stochastic Differential Decision Systems with Different Information Structures-Part II: Applications
(2017)In this second part of the two-part paper, a stochastic maximum principle, conditional Hamiltonians and the coupled backward-forward stochastic differential equations (SDEs) of the first part [1] are employed to derive ...

Encoder-decoder design for perfect reconstruction: A robust control perspective
(2005)In this paper we consider the transmission of discrete data via a communication channel that is subject to (additive) noise with a known upper bound on its magnitude but otherwise completely unknown. We are interested in ...

Frequentist optimality of bayes factor estimators in wavelet regression models
(2007)We investigate the theoretical performance of Bayes factor estimators in wavelet regression models with independent and identically distributed errors that are not necessarily normally distributed. We compare these estimators ...

Minimax rates of convergence and optimality of bayes factor wavelet regression estimators under pointwise risks
(2009)We consider function estimation in nonparametric regression over Besov spaces and under pointwise lu-risks (1 ≤ u < ∞). First we derive both non-adaptive and adaptive minimax pointwise rates of convergence in the standard ...

On optimal signaling over secure MIMO channels
(2012)Optimal signalling over the wire-tap MIMO Gaussian channel is studied under the total transmit power constraint. A direct proof of the necessary condition of optimality (signaling on the positive directions of the difference ...

On pointwise optimality of Bayes factor wavelet regression estimators
(2006)We investigate the theoretical performance of Bayes factor estimators at a single point in wavelet regression models with independent and identically distributed errors that are not necessarily normally distributed. We ...

Optimal encoder and control strategies in stochastic control subject to rate constraints for channels with memory and feedback
(2011)This paper is concerned with the joint design of encoder/control strategies which minimize a control payoff subject to a rate constraint on the feedback information provided by the system. The control system is described ...

Optimal measurement strategy for nonlinear filtering
(2006)In this paper we consider the question of an optimal measurement strategy for nonlinear filtering. Given a set of measurement and observation options, the problem faced by a designer is to choose the option that gives the ...
