Bayesian belief network

Bayesian belief network

An inference technique which provides a framework for reasoning despite uncertainty, based on the theory of probability. In a Bayesian belief network, each fact/assertion in the knowledge base is represented by a node.

In order to find some relationships between the risk of the software and the metrics extracted from the code of the national project related software system, in this paper, we applied four classical intelligent classification methods which were most used in data mining fields, namely Bayesian belief networks (BBN) [1, 2, 3], nearest neighbor (NN) [4] rough set (RS) and decision tree (DT) [5], [6], to predict the risk of the core source code of a spectrum processing software system which is a "863" National Project related to the Large Sky Area Multi-Object Spectroscopic Telescope (LAMOST) Project in China.
