Background trends in California Current surface chlorophyll concentrations: a state-space view

by Andrew C. Thomas, Roy Mendelssohn, Ryan Weatherbee - J , 2013
"... [1] State-space models are applied to 13 years of monthly satellite-measured chlorophyll concentrations of the California Current, from British Columbia to Baja California, to isolate the slowly varying background trend from potentially nonstationary seasonal cycles, other higher-frequency cyclical ..."

A tutorial on particle filters for online nonlinear/non-Gaussian Bayesian tracking

by M. Sanjeev Arulampalam, Simon Maskell, Neil Gordon - IEEE TRANSACTIONS ON SIGNAL PROCESSING , 2002
"... Increasingly, for many application areas, it is becoming important to include elements of nonlinearity and non-Gaussianity in order to model accurately the underlying dynamics of a physical system. Moreover, it is typically crucial to process data on-line as it arrives, both from the point of view o ..."

(or “particle”) representations of probability densities, which can be applied to any state-space model and which generalize the traditional Kalman filtering methods. Several variants of the particle filter such as SIR, ASIR, and RPF are introduced within a generic framework of the sequential

Hybrid Automata: An Algorithmic Approach to the Specification and Verification of Hybrid Systems

by Rajeev Alur, Costas Courcoubetis, Thomas A. Henzinger, Pei-Hsin Ho , 1992
"... We introduce the framework of hybrid automata as a model and specification language for hybrid systems. Hybrid automata can be viewed as a generalization of timed automata, in which the behavior of variables is governed in each state by a set of differential equations. We show that many of the examp ..."

Computational Models of Sensorimotor Integration

by Zoubin Ghahramani , Daniel M. Wolpert, Michael I. Jordan - SCIENCE , 1997
"... The sensorimotor integration system can be viewed as an observer attempting to estimate its own state and the state of the environment by integrating multiple sources of information. We describe a computational framework capturing this notion, and some specific models of integration and adaptati ..."

State-Space Optical Flow

by Sandeep Gupta, Jerry L. Prince
"... Optical flow estimators of motion in image sequences are sometimes found using variational frameworks, which produce partial differential equations as the estimators. In this paper, we show that certain state-space formulations, solved by linear smoothing theory, lead to these same solutions. The ad ..."

The Semantic View and the α-model

by Richard Lawrence , 2007
"... In what follows, I discuss the semantic view of theories, specifically in the ‘state space ’ formulation that has been developed by Bas van Fraassen, Frederick Suppe, and others and applied by Elisabeth Lloyd. I consider the claims that the state space view makes about how scientific theories are be ..."

A State-Space Striatal Model

by Christopher I. Connolly , J. Brian Burns - MODELS OF INFORMATION PROCESSING IN THE BASAL GANGLIA , 1995
"... This chapter considers the role of the striatum in computing purposeful state changes. Such state changes include, for example, movement through a maze, or an obstacle-avoiding arm reach. In each of these cases, the system (arm, body, etc.) must make its way from the current state to one or more go ..."

goal states, avoiding undesirable states along the way. Certain properties of the striatum make it a strong candidate for a locus of computation for this problem. Alexander et al. [1] present a compelling view of the basal ganglia as being involved in parallel, functionally segregated circuits

Distributed Constraint Satisfaction for Formalizing Distributed Problem Solving

by Makoto Yokoo, Toru Ishida, Edmund H. Durfee, Kazuhiro Kuwabara , 1992
"... Viewing cooperative distributed problem solving (CDPS) as distributed constraint satisfaction provides a useful formalism for characterizing CDPS techniques. In this paper, we describe this formalism and compare algorithms for solving distributed constraint satisfaction problems (DCSPs). In particul ..."
