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．

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.
