Web信念传播（Belief Propagation）通过消息传递(passing message)的方式，解决概率图模型中的条件概率问题。 这涉及了概率图的相关知识。 算法将变量消去法中的求和操作看作一个消息传递过程，较好地解决了求解多个边际分布时的重复计算问题。 WebBelief read-out Once messages have converged, use belief read-out equation: If you normalize belief then it approximates the marginal probability. (Approximation … the wave and particle models of light

Web29 okt. 2011 · Message-passing algorithms can solve a wide variety of optimization, inference, and constraint satisfaction problems. The algorithms operate on factor graphs that visually represent and specify the structure of the problems. After describing some of their applications, I survey the family of belief propagation (BP) algorithms, beginning with a … WebHow to Use these Messages 1.Select the root, or pick one if a tree a) Send messages from leaves to root b) Send messages from root to leaves c) Use messages to compute (unnormalized) marginal probabilities 2.Are we done? a) If a tree structure, we’ve converged b) If not: i. Either accept the partially converged result, or… ii. Go back to (1 ... the wave amsterdam noord
