Abstract

Data-mining is concerned with extracting knowledge from databases (in this case we deal with distributed ones) using machine-learning techniques. Traditionally, data-mining systems are designed to work on a single data set. With the large number of distributed databases dispersed in WANS with geographically spread locations, or in Internet, it is necessary to adopt new techniques to improve the mining results. The development of Bayesian belief networks and associated algorithms made possible that probabilistic reasoning becomes a real option for a large variety of Artificial Intelligence applications. In this paper we present a methodology for machine learning using Bayesian belief network with practical exemplification for predicting arteriosclerosis cardiovascular disease, with data located on different sites across a computer network.
