| 摘 要： | 本文提出了一件波形的符号化方法——树表达法,利用这种方法可以将各种感知数据换成专家系统易于接受且便于推理的知识表达形式.文中讨论了树的性质,树结点的表达方法及树的生成算法;根据波形分析的特点,提出了一个层次模型,将波形分析过程分为5个步骤:a.信号检测;b.预处理;c.波形分段;d.波形识别;e.基于领域知识的波形解释.

| Abstract: | A symbolic representation of waveform, the tree representation, ,which can transform all kinds of sensed data into a knowledge representation form utilized in expert systems is presented. The properties of the tree, the expression for the tree node and a new algorithm for tres generation are discussed. Waveform analysis based on tree representation is given in five steps: (1) signal detection; (2) preprocessing; (3) segmentation; (4) recognition and (5) interpretation based on domain-special knowledge. A hierarchical model for waveform analysis based on the tree representation is suggested. |
