Multicast-based loss inference with missing data
收藏 引用
IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS 2002年 第4期20卷 700-713页
作者: Duffield, NG Horowitz, J Towsley, D Wei, W Friedman, T AT&T Labs Res Florham Pk NJ 07932 USA Univ Massachusetts Dept Math & Stat Amherst MA 01003 USA Univ Massachusetts Dept Comp Sci Amherst MA 01003 USA
Network tomography using multicast probes enables inference of loss characteristics of internal network links from reports of end-to-end loss seen at multicast receivers. In this paper, we develop estimators for inter... 详细信息

A Bayesian EM algorithm for optimal tracking of a maneuvering target in clutter
收藏 引用
SIGNAL PROCESSING 2002年 第3期82卷 473-490页
作者: Logothetis, A Krishnamurthy, V Holst, J Ericsson Telecom AB S-12625 Stockholm Sweden
The difficulty in tracking a maneuvering target in the presence of false measurements arises from the uncertain origin of the measurements (as a result of the observation detection process) and the uncertainty in the ... 详细信息

Kalman filtering of a space-time Markov random field
收藏 引用
MATHEMATICAL AND COMPUTER MODELLING 2002年 第11-13期36卷 1193-1209页
作者: Aggoun, L Sultan Qaboos Univ Dept Math & Stat Al Khoud 123 Oman
In this paper, finite-dimensional recursive filters for space-time Markov random fields are derived. These filters can be used with the expectation maximization (EM) algorithm to yield maximum likelihood estimates of ... 详细信息

1st International IEEE Symposium on Intelligent Systems
作者: Alexiev, KM Bulgarian Acad Sci Cent Lab Parallel Proc BU-1113 Sofia Bulgaria
The problem of estimating the parameters that determine a mixture density has been subject of extraordinary interest in the last years. Such a mixture density estimation problem is multi-target tracking. One of the ne... 详细信息

IEEE International Conference on Acoustics, Speech, and Signal Processing
作者: Taleb, A Ericsson Radio Syst AB SE-16480 Stockholm Sweden
This paper concerns the application of the EM algorithm for the estimation of the parameters of non-stationary noisy phase mono component signals buried in additive noise. Noisy phase signals are appropriate for model... 详细信息

Accelerating EM for large databases
收藏 引用
MACHINE LEARNING 2001年 第3期45卷 279-299页
作者: Thiesson, B Meek, C Heckerman, D Microsoft Corp Res Redmond WA 98052 USA
The EM algorithm is a popular method for parameter estimation in a variety of problems involving missing data. However, the EM algorithm often requires significant computational resources and has been dismissed as imp... 详细信息

Unsupervised retraining of a maximum likelihood classifier for the analysis of multitemporal remote sensing images
收藏 引用
IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING 2001年 第2期39卷 456-460页
作者: Bruzzone, L Prieto, DF Univ Trent Dept Civil & Environm Engn Trento Italy
An unsupervised retraining technique for a maximum likelihood (ML) classifier is presented. The proposed technique allows the classifier's parameters, obtained by supervised learning on a specific image, to be upd... 详细信息
