通俗的说 ：原本的图有环(如果是长度大于3的环需要映入chord)，那么我们可以将几个相邻的节点合并为一个大的节点，可以消除原本存在的环。把所有原本存在的环路变为一个个超级节点，图就变成了树，这就是junction tree 能够hold主环路的原因 通过证明，无论是贝叶斯网络还是马儿克夫网络的联合概率都能够...

40-45, 2010 we also proved that the best approximating k - 1-width junction tree probability distribution can be embedded into a k-th order cherry tree probability distribution. We introduce here a greedy algorithm resulting very good approximations in reasonable computing time. We prove then ...
拟采用通过将贝叶斯网路转化为联合树(junction tree)与Graph-Cut 算法来实现尺度化的并行算法。系统框图:clip_image002.gif www.openhw.org|基于15个网页 2. 结树 ...通过聚类变量,把给定的有向无环图转化成一棵树,称作结树(junction tree),使得信念传播能够完成(Lauritzen和Spiegelhalte… ...
Junction tree:从clique graph 中找到最大支撑树 Potential Assignment:将原来各个变量的条件概率乘入到所属clique的potential中 Message Propagation: 每条边的两个方向都需要做一次message passing 最终clique的potential就是边缘概率。 只有原图为树形时,JTA才是线性的时间复杂度 ...
