基于算法适用知识的挖掘算法选择交互系统

A System of Mining Algorithm Selection Based on Algorithm Suiting Knowledge

为具体挖掘任务选择合适的挖掘算法需要用户对挖掘任务、各种挖掘算法和数据特征都非常熟悉,一般用户是很难达到这个要求的。针对以往研究的系统存在实现困难、不能适应动态添加算法等不足,文中形式化表示数据挖掘算法的适用知识,并基于此设计算法选择交互问题和选择逻辑,实现了一个易于实现的数据挖掘算法选择交互系统。实例验证了系统的有效性。

Appropriate algorithm could be selected by data mining user only when he is very familiar with mining task, all kinds of algorithms and data features. It＇ s difficult for ordinary user to do it. Aiming at shortcomings of past works, algorithm suiting knowledge is represented formally. Based on the algorithm, interactive questions and selection logic are designed. An easy-to-implemented system of data mining algorithm selection is realized. An example shows the efficiency of the algorithm.
