Tutorial on How to Measure Link Strengths in Discrete Bayesian Networks

摘要: This report discusses measures for link strength in Discrete Bayesian Networks, i.e. the of connection along a specific edge. It is revised version Report GT-IIC-07-01 (Jan 2007) with improved literature review and explanations. The target application visualization strengths edge connections Network learned from data to learn more about inherent properties system. reviews existing measures, provides an accessible derivation primary measure, proposes some simple variations measure compares their resulting properties. 1 Concept Link Strength Boerlage was first formally introduce concept Networks (Boerlage 1992). defines any pair nodes (adjacent or not) between those taking possible path them into account. In contrast (also known as arc weight) defined only that single To demonstrate difference these concepts particular adjacent consider network Figure 1. Each three has two states, True False.
