摘要:

在这项工作中,我们提出了切割平面推理(CPI),统计关系学习的最大后验概率(MAP)推理方法。它以马尔可夫逻辑为框架,并受到切割平面方法的启发,可以被视为一种Meta算法,该算法实例化大型复杂马尔可夫网络的小部分,然后使用传统的MAP方法解决这些问题。我们评估CPI的两个任务,语义角色标签和联合实体解析,同时插入两种不同的MAP推理方法:当前选择的方法在马尔可夫逻辑,MaxWalkSAT和线性规划的MAP推理。我们观察到,当与CPI一起使用时,这两种方法都比单独使用时要快得多。另外,CPI提高了MaxWalkSAT的精度,保持了线性规划的精确性。

英文摘要:

In this work we present Cutting Plane Inference (CPI), a Maximum A Posteriori (MAP) inference method for Statistical Relational Learning. Framed in terms of Markov Logic and inspired by the Cutting Plane Method, it can be seen as a meta algorithm that instantiates small parts of a large and complex Markov Network and then solves these using a conventional MAP method. We evaluate CPI on two tasks, Semantic Role Labelling and Joint Entity Resolution, while plugging in two different MAP inference methods: the current method of choice for MAP inference in Markov Logic, MaxWalkSAT, and Integer Linear Programming. We observe that when used with CPI both methods are significantly faster than when used alone. In addition, CPI improves the accuracy of MaxWalkSAT and maintains the exactness of Integer Linear Programming.
