基于贪心思想的数值属性离散化算法的改进

A Modified Discretization Algorithm of Numerical Attributes Based on Greedy Strategy

对现有的数值属性离散化算法进行研究,客观地评价了它们的优缺点,并在此基础上针对基于贪心思想的数值属性离散化算法的不足,提出了一种新的改进算法.最后通过算法示例验证表明这种改进算法是有效、可行的.

It carries out a survey on existing discretization methods of numerical attributes, and evaluates their advantages and disadvantages objectively. On the basis of that, a new improved algorithm is presented according to the disadvantages of discretization algorithm of numerical attributes based on greedy strategy. Finally, the improved algorithm is verified by examples and the results show that the algorithm is effective and feasible.
