The Development and Application of Bayesian Networks Used in Data Mining Under Big Data

Abstract

Big data era has arrived. With the rapid development of big data, the machine learning based on probability statistics has drawn great attention in recent years from both industry and academia. It also has great applications in the fields of the Internet, finance, natural language, biology, among which the Bayesian network has experienced significant development last year and has become a kind of important machine learning method. This paper summarizes the data mining concept principle and basic method of data mining under the background of big data. Since data mining has strong statistic characteristic, it can be integrated with the Bayesian networks naturally. Therefore, this paper starts with the Bayesian networks, stretching out the Bayesian formula, Bayesian network technology, as well as the advantages of the combination of data mining and the Bayesian networks. Finally, with the biomedicine as an example, it summarizes its development and applications.
