对不相容决策表分别使用3种知识约简方法(代数方法、信息熵方法和差别矩阵方法)得到的结果可能不同。在此概括这些知识约简并介绍其在分析不相容决策表中的作用。因此对于知识约简方法的选择,可以由不同决策粒度的需求决定,从而可以在相似和不确定推理的模型下生成合适的决策规则。结论对今后数据预处理的模型和算法的研究有一定作用。
The results of using three knowledge reduction methods (algebra method, information entropy method and difference matrix method) for incompatible decision tables may be different. Here’s a summary of these knowledge reductions and describes their role in analyzing incompatible decision-making tables. Therefore, the choice of knowledge reduction method can be determined by the demand of different decision-making granularity, so that the appropriate decision rules can be generated under the similar and uncertain inference models. Conclusion The research on the model and algorithm of data preprocessing in the future has a certain effect.
