Tutorial on How to Measure Link Strengths in Discrete Bayesian Networks
Abstract
This report discusses measures for link
strength in Discrete Bayesian Networks, i.e.
measures for the strength of connection along
a specific edge. It is a revised version of Report GT-IIC-07-01 (Jan 2007) with improved
literature review and explanations.
The target application is the visualization
of the strengths of the edge connections in
a Bayesian Network learned from data to
learn more about the inherent properties of
the system. The report reviews existing
link strength measures, provides an accessible derivation of the primary measure, proposes some simple variations of the primary measure and compares their resulting properties.
