摘要
文中在简单遗传算法的基础上 ,利用改进的算法进行关联规则的发现和数据库中特征项权重的发现 ,通过对农业气象数据库的实验 ,力求解决遗传算法中的早熟等问题。
Data Mining in Database is a new research direction in the field of information science. Based on the simple genetic algorithm (GA), this paper shows how to implement the data mining with an improved algorithm, discovering knowledge and finding an optimal or near optimal weight vector for the attributes from an agricultural weather database by experimenting with the improved algorithm. Finally we try to solve the problem of premature convergence of GA.
