通过删除然后校正模型边缘来近似配分函数
Approximating the Partition Function by Deleting and then Correcting for Model Edges
摘要：
我们提出了一种方法来近似的分区函数，这是基于两个步骤：（1）计算分区函数的简化模型，这是通过删除模型的边缘，（2）纠正的结果，通过应用边缘边缘的校正。该方法导致一个直观的框架，其中可以权衡的质量近似计算的复杂性。它还包括贝特自由能近似作为一个退化的情况下。我们在本文中理论上开发的方法，并提供了一些实证结果，揭示其实际效用。
英文摘要：
We propose an approach for approximating the partition function which is based on two steps: (1) computing the partition function of a simplified model which is obtained by deleting model edges, and (2) rectifying the result by applying an edge-by-edge correction. The approach leads to an intuitive framework in which one can trade-off the quality of an approximation with the complexity of computing it. It also includes the Bethe free energy approximation as a degenerate case. We develop the approach theoretically in this paper and provide a number of empirical results that reveal its practical utility.
