摘要 提出了一种频数监督断点的离散化算法。该算法利用所提出的频数监督断点思想产生初始断点,并在此基础上进行断点简约。实验结果表明该算法所产生的断点不仅符合实际数据分布,而且更为合理、精练。 In this paper,a discrete algorithm is proposed based on the frequency supervised breakpoint which is applied to the conditional continuous attributes.The algorithm adopts the idea of frequency supervised breakpoint that is brought forward to gencrate initial breakpoints.On the basis of the preparatory work,reduction of breaktpoints has been performed.The result obtained shows clearly the breakpoints generated by this algorithm not only are in line with the actual data distribution but also they are more reasonable, refined.
