Interpretation Method of Guqin （Chinese Ancient Zither ） Notation Based on Radical and Structural Analysis

Guqin music is a precious cultural heritage of China. The notation of Guqin is very special, which records its playing methods and techniques. For the purpose of preserving the guqin art, the digitalization of guqin notation and an interpretation method of guqin notation were conducted. By using this interpretation method, raw images of handwritten notations are transformed into structural data that can be processed and analyzed by computers easily. The method decomposes each single complex character of guqin notations into simple radicals and finds the structure of the character. According to the radicals and the structure, the character is interpreted into meaningful codes. The experimental results show our method is effective.     

基于遗传算法的分类规则序列生成

与当前常用的分类方法相比,遗传算法具有较强的伸缩性和全局搜索能力,易于并行计算等优点.但通过遗传算法得到的一组分类规则之间常常存在冲突.本文先将分类规则表示成二进制编码,采用F-measure作为适应度评估函数,并设计了有效的杂交,变异等遗传算子,使遗传算法适合用在分类规则挖掘中.在遗传算法中增加了冲突解决机制,并结合顺序覆盖算法,使之可以得到分类规则的序列,解决了规则问的冲突,形成了一个完整的分类方法.最后针对具体实例作了测试,并将实验结果与分类算法J4.8得到的结果进行了对比,表明该方法略优于J4.8.
