中文简介:
本文的目的有两个:(1)介绍决策支持(DS)领域,(2)概述将DS与数据挖掘(DM)结合在一起解决现实生活中的决策和数据分析问题的可能方法和好处。与决策相关,我们定义了决策问题和决策的概念,介绍了与决策相关学科的分类,概述了决策分析的方法,介绍了多属性建模的方法,并通过现实生活中住房贷款分配和医学风险评估的实例加以说明。在主要部分,我们研究了将DS和DM结合和集成的方法,一般分为(1)DS用于DM, (2) DM用于DS, (3) DM,然后是DS, (4) DS,然后是DM, (5) DM和DS。每个类别都用一个实际例子加以说明。本文对两类问题进行了更详细的研究。DM&rdquo的类别(1)DS;给出了一种基于ROC空间探测的最佳dm诱导分类器的选择方法。针对类别(5)DM和DS&rdquo,我们探索了一种结合系统DEX和HINT开发定性多属性模型的方法。DEX是一款基于专家经验(手工制作)的模型开发的DS工具,而HINT是一款基于功能分解的方法从数据中开发模型的DM工具。
课程简介: The aim of this presentation is twofold: (1) to introduce the field of Decision Support (DS), and (2) to provide an overview of possible approaches and benefits of combining DS with Data Mining (DM) in solving real-life decision and data-analysis problems. Related to DS, we define the concepts of decision problem and decision-making, introduce the taxonomy of disciplines related to DS, overview the approach of decision analysis, introduce the method of multi-attribute modeling, and illustrate it through real-life examples of housing loan allocation and risk assessment in medicine. In the main part, we investigate the ways to combine and integrate DS and DM, which generally involve the following categories: (1) DS for DM, (2) DM for DS, (3) DM, then DS, (4) DS, then DM, and (5) DM and DS. Each category is illustrated by a practical example. Two categories are investigated in greater detail. The category “(1) DS for DM” is represented by a method for selecting a best DM-induced classifier based on ROC space exploration. For the category “(5) DM and DS”, we explore an approach of developing qualitative multi-attribute models by combining the systems DEX and HINT. DEX is a DS tool for expert-based (“hand-crafted”) development of models, whereas HINT is a DM tool that develops models from data by a method based on function decomposition.
