Effective Planning Horizons for Robust Autonomy (2009)
Robust autonomy, in the sense of performing tasks in the face of dynamic changes to the environment, requires that an autonomous system be capable of responding appropriately to such changes. One...
W.N.: Multiple viewpoints: A strategy for searching multimedia content (2008)
James C. French, A. C. Chapin, W. N. Martin
Abstract. Multiple viewpoint systems are an approach to information retrieval that takes advantage of having more than one source of judgments on a body of information. Multiple viewpoints can...
Problem Perturbation: Implications on the Fitness Landscape (2008)
W. N. Martin, A. L. Barker, J. P. Cohoon
Abstract- We present the concept of “problem perturbation“, give the specifications of an application to the Travenling Salesperson Problem (TSP), then discuss an empiricd study of the fitness...
ANALYSIS OF SCENES CONTAINING SEVERAL OCCLUDING CURVILINEAR OBJECTS (2007)
K. R. Yam, W. N. Martin, J. K. Aggarwal
This report describes the techniques used and the results obtained by a system developed to analyze edge pictures derived from scenes containing several occluding curvilinear objects. A library of...
W.: An empirical investigation of the scalability of a multiple viewpoint cbir system (2004)
James C. French, Xiangyu Jin, W. N. Martin
Abstract. Our work in content-based image retrieval (CBIR) relies on content-analysis of multiple representations of an image which we term multiple viewpoints or channels. The conceptual idea is to...
Integrating Multiple Multi-Channel CBIR Systems (Extended Abstract) (2003)
James C. French, Xiangyu Jin, W. N. Martin
James C. French James V. S. Watson Xiangyu Jin W. N. Martin Department of Computer Science University of Virginia Charlottesville, VA 01-434-982-2213 {french,jvw3n,xj3a,wnm}@cs.virginia.edu This work...
James C. French, X. Jin, W. N. Martin
Content-based image retrieval (CBIR) uses features that can be extracted from the images themselves. In previous work we have shown that using more than one representation of the images in a...
Dynamic Scene Analysis: The Study of Moving Images, (2002)
Martin, W. N., Aggarwal, J. K.
Scene analysis has long been a fusion point between the fields of pattern recognition and artificial intelligence: it integrates techniques from both disciplines. Usually, these techniques are...
Dynamics of a Distance-Based Population Diversity Measure (2000)
Allen Barker Datafilter, Allen L. Barker, W. N. Martin
We study a class of steady-state genetic algorithms where, at each time step, two parents are selected to produce a child which then replaces one member of the population at the next time step. We...
Piezoelectric Materials for an Artificial Neural System (1998)
Schulz, M. J., Chattopadhyay, S., Sundaresan, M. J., Ghoshal, A., Martin, W. N.
Piezoelectric materials are opening the door for the design of large smart structures. To explore what possibilities there might be for building practical smart structures, a review of the...
Using genetic programming to evolve board evaluation functions (1996)
Gabriel J. Ferrer, W. N. Martin
In this paper, we employ the genetic programming paradigm to enable a computer to learn to play strategies for the ancient Egyptian boardgame Senet by evolving board evaluation functions. Formulating...
