摘要:

贝叶斯信念网络学习(Bayesian Learning of Belief Networks,BLN)是一种使用搜索和贝叶斯评分技术从数据中自动构建信念网络的方法。K2是实现贪婪搜索策略的方法的特定实例。为了评估K2的准确性,我们随机生成了一些BN,并为每个BN模拟了数据集。然后使用K2从模拟数据中诱导生成BN。我们检查的程序的性能,以及影响它的因素。我们还提出了一个简单的BN模型,从我们的结果,它预测的精度K2,当给定的数据集的各种特性。

英文摘要:

Bayesian learning of belief networks (BLN) is a method for automatically constructing belief networks (BNs) from data using search and Bayesian scoring techniques. K2 is a particular instantiation of the method that implements a greedy search strategy. To evaluate the accuracy of K2, we randomly generated a number of BNs and for each of those we simulated data sets. K2 was then used to induce the generating BNs from the simulated data. We examine the performance of the program, and the factors that influence it. We also present a simple BN model, developed from our results, which predicts the accuracy of K2, when given various characteristics of the data set.
