摘要:

提出了一种新的无圈因子图消息传递算法。所提出的“熵消息传递”(EMP)算法可以被看作是在熵半环上的和积消息传递,这已经出现在自动机理论中。EMP的主要用途是计算模型的熵。但是,EMP也可以用于计算出现在期望最大化和梯度下降算法中的表达式。

英文摘要:

The paper proposes a new message passing algorithm for cycle-free factor graphs. The proposed "entropy message passing" (EMP) algorithm may be viewed as sum-product message passing over the entropy semiring, which has previously appeared in automata theory. The primary use of EMP is to compute the entropy of a model. However, EMP can also be used to compute expressions that appear in expectation maximization and in gradient descent algorithms.
