摘要
介绍了遗传算法在储粮害虫特征选择中的应用,对遗传算法的思想、实现步骤、参数选择分析及具体实现等进行了重点阐述.该算法有效地将粮虫的17维原始形态学特征降为10维,提高了分类的效率.在粮库现场系统能以86.5%的正确率将12种常见的粮虫区别开来.
The application of genetic algorithm in stored-grain pest feature selecting is introduced briefly. The basic idea,steps,parameter selecting and material realization of the genetic algorithm are discussed in detail in feature selecting. The 17-dimension morphologic features of the stored-grain pests are compressed into 10 dimensions effectively and the classification efficiency is improved. The system can recognise the 12 kinds of familiar stored-grain pests in grain depot and the correct recognition ratio is over 86.5%.
