摘要:

数据离散化是机器学习过程中的一个重要步骤,因为离散属性比连续属性更容易被分类器处理。多年来,执行离散化的几种方法,如布尔推理,等频率分箱,熵已被提出,探索和实现。本文介绍了一种简单的监督离散化方法。MIL的主要目标是最大化分类器的分类精度,最小化连续属性离散化时的信息损失。建议的方法的性能进行了比较与监督离散化算法最小信息损失(MIL),使用最先进的规则归纳算法-J 48(Java实现的C4.5分类器)。所提出的方法,事实上,修改后的版本MIL。实验结果表明,修改后的方法在几种情况下表现得更好,相比原来的MIL算法和最小描述长度原则(MDLP)。

英文摘要:

Data discretization is an important step in the process of machine learning, since it is easier for classifiers to deal with discrete attributes rather than continuous attributes. Over the years, several methods of performing discretization such as Boolean Reasoning, Equal Frequency Binning, Entropy have been proposed, explored, and implemented. In this article, a simple supervised discretization approach is introduced. The prime goal of MIL is to maximize classification accuracy of classifier, minimizing loss of information while discretization of continuous attributes. The performance of the suggested approach is compared with the supervised discretization algorithm Minimum Information Loss (MIL), using the state-of-the-art rule inductive algorithms- J48 (Java implementation of C4.5 classifier). The presented approach is, indeed, the modified version of MIL. The empirical results show that the modified approach performs better in several cases in comparison to the original MIL algorithm and Minimum Description Length Principle (MDLP) .
