The problem of learning Bayesian network structure is well known to be NP–hard. It is therefore very important to develop efficient approximation techniques. We introduce an algorithm that within the framework of influence diagrams translates the structure learning problem into the strategy optimisation problem, for which we apply the Chen’s self–annealing stochastic optimisation algorithm. The...

Gregory F. Cooper Medical Computer Science Group Medical School Office Building Stanford University Stanford, CA 94305 This paper demonstrates a method for using belief-network algorithms to solve influence­ diagram problems. In particular, both exact and approximation belief-network algorithms may be applied to solve influence-diagram problems. More generally, knowing the relationship between ...

We consider a two-loop contribution of Higgs-mediated penguin diagram to B(Bs → μ+μ−) at large tanβ in the MSSM, motivated by a recently proposed two-loop magnetic penguin diagrams by Chen and Geng [1]. Typically the two-loop diagram is a αs correction to the one-loop contributions. However the new contribution can dominate one-loop contributions in a region of parameter space where μ, At and A...

Database design is one of the main topics of any introductory database course. Traditionally, for teaching it entity-relationship diagrams (ERD) are used. However, in the last years, Unified Modeling Language (UML) has emerged as an effective modeling tool for database design. In this paper we present a web-based tool designed to give support to teaching and learning conceptual database design ...

Recently it has been shown that the heuristic Rosenfeld functional derives from the virial expansion for particles which overlap in one center. Here, we generalize this approach to any number of intersections. Starting from the virial expansion in Ree-Hoover diagrams, it is shown in the first part that each intersection pattern defines exactly one infinite class of diagrams. Determining their a...

The purpose of the application view is described. A number of methods or models is given to use in this view: stakeholder and concerns, context diagram, static entity relationship models and dynamic flow models. Distribution This article or presentation is written as part of the Gaudí project. The Gaudí project philosophy is to improve by obtaining frequent feedback. Frequent feedback is pursue...

In the paper the problem of verification of functional programs (FPs) over strings is considered, where specifications of properties of FPs are defined by other FPs, and a FP Σ1 meets a specification defined by another FP Σ2 iff a composition of functions defined by the FPs Σ1 and Σ2 is equal to the constant 1. We introduce a concept of a state diagram of a FP, and reduce the verification probl...

BACKGROUND The Quality of Reporting of Meta-analyses (QUOROM) statement provides guidance for improving the quality of reporting of systematic reviews and meta-analyses. To make the process of study selection transparent it recommends "a flow diagram providing information about the number of RCTs identified, included, and excluded and the reasons for excluding them". We undertook an empirical s...

Provides a brief overview of the activities of the IFLA Functional Requirements for Subject Authority Records (FRSAR) working group. Introduces the group’s terms of reference and the work completed so far, including definitions of user tasks and subject entities. Discusses the development of the entity-relationship conceptual model of subject entities in the bibliographic universe.
