Abstract

Many engineering phenomena of interest are characterized by non-homogeneity. The authors discuss how the intertwining of the partitioning and discovery processes enables KEDS to learn relationships from engineering data and to extract the structure underlying these relationships. They present the KEDS algorithm and discuss the interaction between the two discovery and partitioning phases. Some extensions to the basic algorithm are described that greatly improve the performance of KEDS and increase the representation power of the models by permitting a probabilistic partitioning of the problem space. The results from running the KEDS system on data from a simulator for an internal combustion engine are presented.<>
基于知识的工程问题方程发现系统
许多令人感兴趣的工程现象都具有非同质性。作者讨论了划分和发现过程如何交织在一起,使KEDS能够从工程数据中学习关系,并提取这些关系背后的结构。他们提出了KEDS算法,并讨论了两个发现和划分阶段之间的相互作用。描述了对基本算法的一些扩展,这些扩展通过允许问题空间的概率划分大大提高了KEDS的性能并增加了模型的表示能力。本文给出了KEDS系统在内燃机模拟器数据上的运行结果。
