Fusion, Propagation, and Structuring in Belief Networks

by Judea Pearl - ARTIFICIAL INTELLIGENCE , 1986
"... Belief networks are directed acyclic graphs in which the nodes represent propositions (or variables), the arcs signify direct dependencies between the linked propositions, and the strengths of these dependencies are quantified by conditional probabilities. A network of this sort can be used to repre ..."

with the task of fusing and propagating the impacts of new information through the networks in such a way that, when equilibrium is reached, each proposition will be assigned a measure of belief consistent with the axioms of probability theory. It is shown that if the network is singly connected (e.g. tree

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 ..."

information from visual and auditory systems is integrated so as to reduce the variance in localization. (2) The effects of a remapping in the relation between visual and auditory space can be predicted from a simple learning rule. (3) The temporal propagation of errors in estimating the hand

Recursive Distributed Representations

by Jordan B. Pollack - Artificial Intelligence , 1990
"... A long-standing difficulty for connectionist modeling has been how to represent variable-sized recursive data structures, such as trees and lists, in fixed-width patterns. This paper presents a connectionist architecture which automatically develops compact distributed representations for such compo ..."

for such compositional structures, as well as efficient accessing mechanisms for them. Patterns which stand for the internal nodes of fixed-valence trees are devised through the recursive use of back-propagation on three-layer autoassociative encoder networks. The resulting representations are novel

Gravity coupled with matter and the foundation of non commutative geometry

by Alain Connes , 1996
"... We first exhibit in the commutative case the simple algebraic relations between the algebra of functions on a manifold and its infinitesimal length element ds. Its unitary representations correspond to Riemannian metrics and Spin structure while ds is the Dirac propagator ds = ×— × = D −1 where D i ..."

Multicast-Based Inference of Network-Internal Characteristics: Accuracy of Packet Loss Estimation

by R. Caceres, N.G. Duffield, J. Horowitz, D. Towsley, T. Bu - IEEE Transactions on Information Theory , 1998
"... We explore the use of end-to-end multicast traffic as measurement probes to infer network-internal characteristics. We have developed in an earlier paper [2] a Maximum Likelihood Estimator for packet loss rates on individual links based on losses observed by multicast receivers. This technique explo ..."

BotHunter: Detecting Malware Infection Through IDS-Driven Dialog Correlation

by Guofei Gu, Phillip Porras, Vinod Yegneswaran, Martin Fong, Wenke Lee , 2007
"... We present a new kind of network perimeter monitoring strategy, which focuses on recognizing the infection and coordination dialog that occurs during a successful malware infection. BotHunter is an application designed to track the two-way communication flows between internal assets and external ent ..."

Transition Density, A New Measure of Activity in Digital Circuits

by Farid N. Najm - IEEE Transactions on Computer-Aided Design , 1992
"... Reliability assessment is an important part of the design process of digital integrated circuits. We observe that a common thread that runs through most causes of run-time failure is the extent of circuit activity, i.e., the rate at which its nodes are switching. We propose a new measure of activity ..."

of activity, called the transition density, which may be defined as the "average switching rate" at a circuit node. Based on a stochastic model of logic signals, we also present an algorithm to propagate density values from the primary inputs to internal and output nodes. To illustrate the practical

Session 2520 Considering Numerical Error Propagation in Modeling and Regression of Data

by Neima Brauner, Mordechai Shacham
"... The use of user-friendly interactive regression software enables undergraduate engineering students to reach a high level of sophistication in regression, correlation and analysis of data. In order to interpret correctly the results, the students must be familiar with potential causes for poor fits ..."

They should also be aware of the practical consequences of using a correlation which has no statistical validity. In this paper, the harmful effects of numerical error propagation (resulting from collinearity among

On ellipsoidal techniques for reachability analysis. Part II. Internal Approximations Box-valued constraints
