The study of belief change has been an active area in philosophy and AI. In recent years two special cases of belief change, belief revision and belief update, have been studied in detail. Belief revision and update are clearly not the only possible notions of belief change. In this paper we investigate properties of a range of possible belief change operations. We start with an abstract notion...

In this paper, we review recent applications of Dempster-Shafer theory (DST) of belief functions to auditing and business decision-making. We show how DST can better map uncertainties in the application domains than Bayesian theory of probabilities. We review the applications in auditing around three practical problems that challenge the effective application of DST, namely, hierarchical eviden...

This paper proposes a dynamically-changed knowledge system. Each belief in the system has a component reflecting the strength of support from other people. The system is capable of adapting to a contextual situation by means of the continuous revision of belief strengths through interaction with others. As a paradigmatic application of the proposed socially-supported belief system, a parser was...

Brewka and Eiter’s nonmonotonic multi-context systems is an elegant knowledge representation framework to model heterogeneous and nonmonotonic multiple contexts. Belief change is a central problem in knowledge representation and reasoning. In the paper we follow the classical AGM approach to investigate belief change in multi-context systems. Specifically, we semantically formulate the AGM post...

This report describes the riso project, a system for uniied prediction and diagnosis in HVAC systems based on a class of probabilistic models called belief networks. Progress has been made in both theoretical and practical problems: a scheme for the representation of belief networks with heterogeneous conditional distributions has been devised, an algorithm for inference in a polytree network w...

unlike teacher beliefs, there has been a dearth of study regarding efl learner beliefs. the reason can be that horwitz (1987) and the existing literature has predominantly been in an esl context. the present study reports the development and validation of a scale to measure the learner beliefs about language learning in iranian efl contexts. using a combination of verbal creativity method, inte...

This paper presents an online planning/replanning strategy for dynamical systems, in the presence of uncertainty. Online replanning capability allows us to handle discrete changes in the goal location. Multi-query graph-based methods, such as PRM in the deterministic setting, and FIRM in the stochastic setting, are suitable frameworks to serve this purpose. However, in these methods, local plan...
