摘要:

在第一-order关系域中调和归纳学习与演绎推理之间的张力一直是人工智能中的长期挑战。我们通过学习和推理的联合努力,研究如何通过第一-order关系概率逻辑回答查询,而无需构建显式模型。传统的提升推断假设可以访问完整模型,并利用对称性来评估概率查询;然而,从不完整、嘈杂的观察中学习此类模型在一般情况下是不可行的。我们通过隐式学习来推理和第一-order关系概率推断技术来调和这两个挑战。更具体地说,我们将不完整的第一-order公理与独立采样、部分观察的例子合并到多项式时间内有界的求和平方(SOS)层次结构的有限度片段中。我们的算法同时执行两种提升:(i) 地面提升,其中重命名等价的地面矩共享一个变量,压缩个体域;(ii) 世界提升,其中所有伪模型(部分世界分配)并行强制,产生一个在所有与学习约束一致的世界中成立的全局界限。这些创新产生了第一个多项式时间框架,能够隐式地学习第一-order概率逻辑,并在个体和世界上执行提升推断。

英文摘要:

Reconciling the tension between inductive learning and deductive reasoning in first-order relational domains is a longstanding challenge in AI. We study the problem of answering queries in a first-order relational probabilistic logic through a joint effort of learning and reasoning, without ever constructing an explicit model. Traditional lifted inference assumes access to a complete model and exploits symmetry to evaluate probabilistic queries; however, learning such models from partial, noisy observations is intractable in general. We reconcile these two challenges through implicit learning to reason and first-order relational probabilistic inference techniques. More specifically, we merge incomplete first-order axioms with independently sampled, partially observed examples into a bounded-degree fragment of the sum-of-squares (SOS) hierarchy in polynomial time. Our algorithm performs two lifts simultaneously: (i) grounding-lift, where renaming-equivalent ground moments share one variable, collapsing the domain of individuals; and (ii) world-lift, where all pseudo-models (partial world assignments) are enforced in parallel, producing a global bound that holds across all worlds consistent with the learned constraints. These innovations yield the first polynomial-time framework that implicitly learns a first-order probabilistic logic and performs lifted inference over both individuals and worlds.
