Nonlinear Filtering and Large Deviations: A PDE-Control Theoretic Approach.
(1987)
We consider the asymptotic nonlinear filtering problem dx = f(x)dt + SQRT EPSILONdw = h(x)dt + SQRT EPSILONdv, and obtain lim_EPSILON-->0 EPSILONlog q^EPSILON(x, t) = -W(x, t) for unnormalized conditional densities ...
The Partially Observed Stochastic Minimum Principle.
(1988)
Various proofs have been given of the minimum principle satisfied by an optimal control in a partially observed stochastic control problem. See, for example, the papers by Bensoussan [1], Elliott [5], Haussmann [7], and ...
Intrusion Detection with Support Vector Machines and Generative Models
(2002)
This paper addresses the task of detecting intrusions in the form of malicious programs on a host computer system by inspecting the trace of system calls made by these programs. We use "attack-tree" type generative models ...
Biologically-Inspired Acoustic Wear Analysis
(2001)
We report on a novel method of acoustic wear analysis using spectral classification based on a model of mammalian audition. This approach uses biologically-inspired pre-processing filters that give a multi- resolution ...
Modeling and Control of a Magnetostrictive Actuator
(2002)
The rate-dependent hysteresis existing in magnetostrictive actuators presents a challenge in control of these actuators. In this paper we propose a novel dynamical model for the hysteresis based on the work of Venkataraman ...
A Practical Transmission System Based on the Human Visual Model for Satellite Channels
(1999)
This paper presents a practical architecture for joint source-channel coding of human visual model-based video transmission over a satellite channel. Perceptual distortion model just-noticeable-distortion (JND) is applied ...
A Carrier Frequency Estimation Method of MPSK Signals and Its Systolic VLSI Implementation
(1999)
In this paper we present an autocorrelation-based method for estimating the carrier frequency offset of an MPSK signal with random data modulation. Although autocorrelation-based techniques imply heavy usage of hardware ...
Maximum Likelihood Slow Frequency-Selective Fading Channel Estimation Using Frequency Domain Approach
(2000)
This paper addresses the channel estimation problem for slow frequency-selective fading channel using training sequence and maximum likelihood (ML) approach. <p>Traditional works assumed symbol period spaced delay-tapped ...
A Decision-Process Analysis of Implicit Coscheduling
(2000)
This paper presents a theoretical framework based on Bayesian decision theory for analyzing recently reported results on implicit coscheduling of parallel applications on clusters of workstations. Using probabilistic ...
Robust Control of Set-Valued Discrete Time Dynamical Systems
(1994)
This paper presents results obtained for the robust control of discrete time dynamical systems. The problem is formulated and solved using dynamic programming. Both necessary and sufficient conditions in terms of (stationary ...
