We consider two particular Bayesian network structures, the so-called nau00efve Bayes and TAN, which have been successfully used as regression models when learning from complete data. We propose an iterative pr
Logistic regression techniques can be used to restrict the conditional probabilities of a Bayesian network for discrete variables. More specifically, each variable of the network can be modeled through a logistic regression model, in which the parents of the variable define the covariates. When all ...
We apply our method to a brain connectome dataset that contains information on brain networks along with a measure of creativity for multiple individuals. Here, interest lies in building a regression model of the creativity measure on the network predictor to identify important regions and connections...
Factor Graph 是概率图的一种,概率图有很多种,最常见的就是Bayesian Network (贝叶斯网络)和Markov Random Fields(马尔可夫随机场)。在概率图中,求某个变量的边缘分布是常见的问题。这问题有很多求解方法,其中之一就是可以把Bayesian Network和Markov Random Fields 转换成Facor Graph,然后用sum-product算法求解。 Bayes...
13proposed an alternative continuous regression-based time-varying DBN withnode-specificchange points, that is, network structures associated with different nodes are allowed to change with time in different ways. These extended DBN models, however, still have obvious limitations, leaving room for ...
一、贝叶斯网络(Bayesian Network) 1.对概率图模型的理解 概率图模型是用图来表示变量概率依赖关系的理论,结合概率论与图论的知识,利用图来表示与模型有关的变量的联合概率分布。 对于一个实际问题,我们希望能够挖掘隐含在数据中的知识。概率图模型构建了这样一幅图,用观测结点表示观测到的数据,用隐含结点表示潜在的...
values are parameters to be optimized. Hence, a modification of Bayesian networks in order to handle continuous variables is an important problem in the gene network estimation problem. A possible solution of this problem is given by using the nonparametric regression introduced in the next section....

Using several breast cancer-specific datasets, we demonstrated the effectiveness of Bayesian network modeling in biological meaningful signal discovery, in comparison with methods of linear regression. Potentially, Bayesian inference can be used to infer dynamic GRN during cell differentiation using new ...
