| 摘 要： | 该文提出了一种新的决策表连续属性离散化算法.首先使用条件信息量来度量条件属性的重要性,并据此对条件属性按照条件信息量从大到小排序,然后按排序后的顺序,考察每个条件属性的所有断点,将冗余的断点去掉,从而将条件属性离散化.该算法易于理解,计算简单.

| Abstract: | In this paper a new discretization algorithm of continue attributes in decision table is offered.Firstly,the conditional information quantity used to measure the importance of condition attributes,according to which the condition attributes are sorted in a descending order.Secondly,all break points of every condition attributes are examined and the redundant ones are eliminated.Finally,each value in the decision table is replaced by a number representing the break point,and then the decision table is discretized.The algorithm is constructed with good understandability and simple computation. |
