This paper describes a formal system of belief revision developed by Wolfgang Spohn and shows thai this system has a parallel implementation that can be derived from an influence diagram in a manner similar to that in which Bayesian networks are derived.

Spatial descriptions indicate the location of one object (a located object) by spatially relating it to another object (a reference object) whose location is presumed to be known or easily found (Beun & Cremers, 1998; Levelt, 1996; Talmy, 1983). A traditional view is that the interpretation of such descriptions is based on the geometry of the objects and their configuration (Herskovits, 1986; L...

* This work has been supported by the Estonian Science Foundation grant G-1850 ABSTRACT: A hierarchical test generation approach to digital circuits, which uses Register-Transfer (RT) and gate level model descriptions, is presented. The proposed test generator implements a novel test generation technique based on Decision Diagram (DD) models. Uniform modeling procedures are used on both levels,...

Although the commonly used Internet Service Provider’s business models based on price comparison may prove to be a successful strategy for organisations in the short term, it may be argued that a sustainable business model for the long term requires a detailed understanding of the various factors that may help ISPs in attracting future customers. This paper therefore examines the influence of a...

In many real-world applications, a mission may consist of several different tasks or phases that have to be accomplished in sequence. Such systems are referred to as phased-mission systems (PMS). In this paper we consider the demand-based PMS with parallel structure, where the system components function in parallel with different capacities in each phase of the mission and the mission is succes...

The main goal of this paper is to describe a new pruning method for solving decision trees and game trees. The pruning method for decision trees suggests a slight variant of decision trees that we call scenario trees. In scenario trees, we do not need a conditional probability for each edge emanating from a chance node. Instead, we require a joint probability for each path from the root node to...

In building Bayesian belief networks, the elic­ itation of all probabilities required can be a major obstacle. We learned the extent of this often-cited observation in the construc­ tion of the probabilistic part of a complex influence diagram in the field of cancer treat­ ment. Based upon our negative experiences with existing methods, we designed a new method for probability elicitation from ...

In this paper we extend the influence diagram (ID) representation for decisions under uncertainty. In the standard ID, arrows into a decision node are only infonnational; they do not represent constraints on what the decision maker can do. We can represent such constraints only indirectly, using arr ows to the children of the decision and sometimes adding more variables to the influence diagram...

On online social networks (OSNs) such as Facebook and Twitter, the massive selfdisclosure has attracted the attention of both academic researchers and marketers. Despite of the impressive scope of this phenomenon, few studies have systematically studies why people self disclose so much on OSNs; let alone what context feature or media capabilities within OSNs will influence people’s voluntary se...

Abstract Mathematical description of an examined system like a Multi-State System (MSS) permits the analysis of this system reliability in more detail, because the MSS defines some performance levels (more that only working and failure). A structure function is one of basic definitions of MSS. But the structure function dimension increases critically depending on the number of system components...
