Applications of minimum principle for continuous-time partially observable risk-sensitive control problems
(IEEE, 1995)This paper employs the minimum principle derived in [1], for nonlinear partially observable exponential of integral control problems, to solve linear-exponential-quadratic-Gaussian (LEQG) tracking problems using two different ...

Bank filters for ML parameter estimation via the Expectation-Maximization algorithm: The continuous-time case
(1998)In this paper we consider continuous-time partially observed systems in which the parameters are unknown. We employ conditional moment generating functions of integrals and stochastic integrals to derive new maximum-likelihood ...

Classes of nonlinear partially observable stochastic optimal control problems with explicit optimal control laws
(1998)This paper introduces certain nonlinear partially observable stochastic optimal control problems which are equivalent to completely observable control problems with finite-dimensional state space. In some cases the optimal ...

Comparing Different Classifiers for Automatic Age Estimation
(2004)We describe a quantitative evaluation of the performance of different classifiers in the task of automatic age estimation. In this context, we generate a statistical model of facial appearance, which is subsequently used ...

Conditional moment generating functions for integrals and stochastic integrals
(2003)In this paper we present two methods for computing filtered estimates for moments of integrals and stochastic integrals of continuous-time nonlinear systems. The first method utilizes recursive stochastic partial differential ...

Conformal Mapping for the Efficient Solution of Poisson Problems with the Kansa-RBF Method
(2017)We consider the solution of Poisson Dirichlet problems in simply-connected irregular domains. These domains are conformally mapped onto the unit disk and the resulting Poisson Dirichlet problems are solved efficiently using ...

Congestion games with player-specific constants
(2007)We consider a special case of weighted congestion games with player-specific latency functions where each player uses for each particular resource a fixed (non-decreasing) delay function together with a player-specific ...

Convergence of belief propagation algorithms on binary pairwise Gibbs random fields
(2011)In this paper, we study the convergence of belief propagation algorithms (BPAs) on binary pairwise Gibbs random fields (BP-GRFs). Exploiting the equivalence of BPA on the graph associated with BP-GRF and the corresponding ...

A DFT study of the ground state multiplicities of linear vs angular polyheteroacenes
(2004)Unrestricted density functional calculations in combination with the broken-symmetry approach and spin-projection methods have been employed to study a series of formally 4n π antiaromatic linear and angular polyheteroacenes. ...

Distributed consensus and linear functional calculation in networks: An observability perspective
(2007)We study the problem of performing sensor fusion and distributed consensus in networks, where the objective is to calculate some linear function of the initial sensor values at some or all of the sensors. We utilize a ...

Eight-Dimensional Quantum Hall Effect and "Octonions"
(2003)A generalization of the quantum Hall effect (QHE) where particles move in an eight-dimensional space under an SO(8) gauge field was constructed. A nonrelativistic Hamiltonian for particles moving on the S8 in the presence ...

Feature mapping through maximization of the atomic interclass distances
(2015)We discuss a way of implementing feature mapping for classification problems by expressing the given data through a set of functions comprising of a mixture of convex functions. In this way, a certain pattern’s potential ...
