【摘要】 <正>1引言如果说数据库是人类观测能力的延伸,则数据挖掘技术是人类分析和发现能力的延伸。人类在自然科学和社会科学的各个领域进行着不断研究,从实验观测数据推测相关事物的内在联系。因此,找到一种高效、准确的函数关系发现方法将对许多学科更多还原

【Abstract】 In many scientific researches,people try to discover the hidden relationships among factors of some certain phenomena.Most of these relationships can be expressed as functions.This paper analyzes the features of function expression and introduces a function discovery method based on Gene Expression Programming.The MEM method can deal with complex functions having n expressions(n>1)in different domains as well as those having only one uniform expression.The article also evaluates the complexity and performance of our method and shows that the MEM method has relatively low complexity due to the use of BDM algorithm and proves that the probability of successful mining is quite high.更多还原
