摘要:

本文通过一般线坐标(GLC)的视觉知识发现,可解释的机器学习。超块作为可解释的数据集单元和一般线坐标的概念相结合,以创建一个可视化的自助机器学习模型。提出了DSC1和DSC2无损多维坐标系。DSC1和DSC2可以使用图形构造算法将多个数据集属性映射到单个二维(X,Y)笛卡尔平面。超块分析用于确定视觉上吸引人的数据集属性顺序并减少线遮挡。结果表明,超块可以推广决策树规则,一系列的DSC1或DSC2图可以可视化一棵决策树。DSC1和DSC2图在UCI ML存储库的基准数据集上进行了测试。它们允许对数据进行视觉分类。此外,还发现了超块杂质区域,并用于建立数据集分割,突出最坏情况下模型准确性的上限估计,以指导高风险决策的模型选择。DSC1和DSC2的主要优点是它们的高度可解释性。它们允许领域专家通过视觉模式发现来控制或建立新的机器学习模型。

英文摘要:

This paper contributes to interpretable machine learning via visual knowledge discovery in general line coordinates (GLC). The concepts of hyperblocks as interpretable dataset units and general line coordinates are combined to create a visual self-service machine learning model. The DSC1 and DSC2 lossless multidimensional coordinate systems are proposed. DSC1 and DSC2 can map multiple dataset attributes to a single two-dimensional (X, Y) Cartesian plane using a graph construction algorithm. The hyperblock analysis was used to determine visually appealing dataset attribute orders and to reduce line occlusion. It is shown that hyperblocks can generalize decision tree rules and a series of DSC1 or DSC2 plots can visualize a decision tree. The DSC1 and DSC2 plots were tested on benchmark datasets from the UCI ML repository. They allowed for visual classification of data. Additionally, areas of hyperblock impurity were discovered and used to establish dataset splits that highlight the upper estimate of worst-case model accuracy to guide model selection for high-risk decision-making. Major benefits of DSC1 and DSC2 is their highly interpretable nature. They allow domain experts to control or establish new machine learning models through visual pattern discovery.
