Exploitation of Landsat imagery and ancillary data for battlespace characterization
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 994-998 vol.2
S.M. Orloff, Su May Hsu, H.-H.K. Burke
Spectral data provide opportunities to discriminate targets from background clutter and to detect partially concealed objects. However, data with high spatial resolution generally are not synoptic scale (hundreds of kilometers). By analyzing courser resolution synoptic imagery, high-resolution sensors can then be cued to areas of potential targets. Multispectral images (Landsat 7) are combined wit...... hiện toàn bộ

Information fusion in a cooperative multi-agent system for web information retrieval
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1256-1262 vol.2

As an attempt to solve some contemporary web information retrieval problems, a construction of a cooperative multiagent system is proposed. This. paper introduces the system and presents the use of a, unique aggregation and fusion technique that is employed to attain reliable delivery performance. The intelligent methodology to fuse agents' decisions, the team consensus approach, models the intera...... hiện toàn bộ

Scalable data fusion using Astrolabe
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1434-1441 vol.2
K.P. Birman, R. van Renesse, W. Vogels
The dramatic growth of computer networks creates both an opportunity and a daunting distributed computing problem for users seeking to perform data fusion and data mining. The problem is that data often resides on large numbers of devices and evolves rapidly. Systems that collect data at a single location scale poorly and suffer from single-point-failures. Astrolabe performs data fusion in real-ti...... hiện toàn bộ

A simple model for reliable query reporting in sensor networks
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1070-1075 vol.2 - 2002
R. Kannan, S. Sarangi, S.S. Iyengar
We consider the problem of inducing the formation of reliable energy-constrained communication paths in distributed sensor networks. We label this problem of reliable information routing from reporting sensors to query nodes as reliable query reporting (RQR) and analyze it using game-theoretic techniques to model the behavior of individual sensor nodes. Sensors behave strategically wherein they ta...... hiện toàn bộ

Fault-tolerant interval estimation fusion by Dempster-Shafer theory
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1605-1612 vol.2
Baohua Li, Yunmin Zhu, X. Rong Li
Fault tolerance is an important issue in network design because sensor networks must work in a dynamic, uncertain situation. In this paper, using Dempster-Shafer theory of evidence, we propose several new fault-tolerant interval integration functions, which give interval estimate fusion outputs and the corresponding belief levels, depending on prior information and practical requirements. Not only...... hiện toàn bộ

Comparison of plot and track fusion for naval sensor integration
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1361-1366 vol.2
S.J. Symons, J.A.H. Miles, J.R. Moon
This paper compares plot and track fusion or a generic suite of sensors that might be available on a future warship, with an emphasis on their relative ability to maintain track continuity in the event of missed measurements/plots. Using plot fusion measurement level data are formed into tracks at a central location, whereas with track fusion state estimate (i.e. track) level data are combined fro...... hiện toàn bộ

A d-step fixed-lag smoothing algorithm for Markovian switching systems
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 1 - Trang 721-726 vol.1
Quan Pan, Y.G. Jia, H.C. Zhang
A suboptimal approach to the d(d /spl ges/ 0) step fixed-lag smoothing problem for Markovian switching systems is presented. Multiple Model Estimation techniques have been widely used in solving state estimation problems of these systems. We demonstrated that the mode probability of each fixed-lag smoother at time k-d (data up to time k), thus it is possible to use Markov transition probability an...... hiện toàn bộ

Real-time multi-model interpolation of range-varying acoustic propagation

This paper presents an efficient method for extracting a multi-model interpolation function from a nonlinear system. The multi-model interpolation function consists of couple simplified time-varying models in neural-network structure to dynamically approximate the nature of the physical phenomena to be interpolated and extrapolated. The purpose of using the multi-model interpolation function is to...... hiện toàn bộ

Distributed reinforcement learning for sequential decision making
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1263-1268 vol.2
G. Rogova, P. Scott, C. Lolett
The paper addresses a problem of reinforcement learning in a homogeneous non-communicating multi-agent system for sequential decision making. We introduce a particular reinforcement learning model composed of evidential reinforcement neural networks representing agents, a fusion center, and a decision maker. The fusion center combines beliefs in each hypothesis under consideration generated by the...... hiện toàn bộ
