我们在这里提出了一种新的方法,在概率非单调域的答案集编程的背景下,规则学习。我们使用的方法来更新基于观察的代理的知识库。为了处理我们的观测数据的概率性质,我们采用参数估计来找到与这些原子中的每一个相关联的概率,从而与规则相关联。其结果是具有最大概率导致观察结果的规则集。与传统的归纳逻辑编程技术相比,这最终提高了对噪声数据的容忍度。我们说明了这种方法的好处,将其应用到规划问题中,所涉及的代理需要非单调性和噪声输入的宽容。
We propose here a novel approach to rule learning in probabilistic nonmonotonic domains in the context of answer set programming. We used the approach to update the knowledge base of an agent based on observations. To handle the probabilistic nature of our observation data, we employ parameter estimation to find the probabilities associated with each of these atoms and consequently with rules. The outcome is the set of rules which have the greatest probability of entailing the observations. This ultimately improves tolerance of noisy data compared to traditional inductive logic programming techniques. We illustrate the benefits of the approach by applying it to a planning problem in which the involved agent requires both nonmonotonicity and tolerance of noisy input.
