摘要:

本文提出了一种可推广的数据抽象知识框架,即利用预定义的抽象术语为输入数据找到紧凑的抽象模型。基于这些抽象术语,智能自治系统(如机器人)应该能够根据特定的知识库进行推理,以便更好地处理现实世界的复杂性和不确定性。我们建议实现这一框架相结合的马尔可夫逻辑网络(MLN)和数据驱动MCMC采样,因为前者是一个强大的工具,为不确定的知识建模和后者提供了一个有效的方法来绘制样本从未知的复杂分布。此外,我们详细展示了如何适应这个框架,以一定的任务,特别是语义机器人映射。基于MLNs,我们制定特定于任务的上下文知识描述性软规则。真实世界的数据和模拟数据的实验证实了我们的框架的实用性。

英文摘要:

In this paper, we propose a generalizable knowledge framework for data abstraction, i.e. finding compact abstract model for input data using predefined abstract terms. Based on these abstract terms, intelligent autonomous systems, such as a robot, should be able to make inference according to specific knowledge base, so that they can better handle the complexity and uncertainty of the real world. We propose to realize this framework by combining Markov logic networks (MLNs) and data driven MCMC sampling, because the former are a powerful tool for modelling uncertain knowledge and the latter provides an efficient way to draw samples from unknown complex distributions. Furthermore, we show in detail how to adapt this framework to a certain task, in particular, semantic robot mapping. Based on MLNs, we formulate task-specific context knowledge as descriptive soft rules. Experiments on real world data and simulated data confirm the usefulness of our framework.
