Bayesian Network for Demand Degree Investigation of the user

Abstract

In order to measure purchase preference on future electronic equipments, we propose a method using Bayesian network. The proposed method is based on three layers network where its causal relationship is sequentially chained by personal attributes, senses of value, and future services. Assigning a variety of evidence to the constructed model with 1,030 samples, we have monitored the sensitivity of probabilities on causality. As a result, for example, "persons who made much of safety prefer products for an inventory management in their house" is found.
