关于配分函数与随机最大后验扰动

On the Partition Function and Random Maximum A-Posteriori Perturbations

Tamir Hazan, Tommi Jaakkola

摘要:

本文将配分函数与随机变量的极大统计量联系起来。特别是,我们提供了一个新的框架,近似和绑定的分区函数使用MAP推理随机扰动模型。因此,我们可以使用有效的MAP求解器,如图切割,以评估相应的分区函数。我们表明,我们的方法在典型的“高信号-高耦合”制度,导致参差不齐的能源景观难以替代的方法。

英文摘要:

In this paper we relate the partition function to the max-statistics of random variables. In particular, we provide a novel framework for approximating and bounding the partition function using MAP inference on randomly perturbed models. As a result, we can use efficient MAP solvers such as graph-cuts to evaluate the corresponding partition function. We show that our method excels in the typical "high signal - high coupling" regime that results in ragged energy landscapes difficult for alternative approaches.
