并行坐标系下的可解释机器学习模型发现

Discovering Interpretable Machine Learning Models in Parallel Coordinates

Central Washington University(中央华盛顿大学)

Boris Kovalerchuk, Dustin Hayes

摘要:

本文通过平行坐标系下的可视化知识发现,研究了可解释的机器学习。超立方体和超块的概念被使用为在平行坐标中以视觉形式容易被最终用户理解。提出了混合超块和纯超块分类的Hyper算法,实现了在单个、多个、重叠和非重叠情况下交互式自动发现超块。超块与视觉模式的语言描述相结合。超模型是决策树的推广。Hyper算法在UCI ML库的基准数据上进行了测试。它允许用所有数据发现纯的和混合的HB,然后用10倍交叉验证。建立了超块、降维和可视化之间的联系。超块技术和Hyper算法的主要好处在于它们能够由最终用户发现和观察超块,包括并排可视化,使模式对所有类可见。HB集合相对于决策树的另一个优点是避免数据过度泛化和过度拟合的能力。

英文摘要:

This paper contributes to interpretable machine learning via visual knowledge discovery in parallel coordinates. The concepts of hypercubes and hyper-blocks are used as easily understandable by end-users in the visual form in parallel coordinates. The Hyper algorithm for classification with mixed and pure hyper-blocks (HBs) is proposed to discover hyper-blocks interactively and automatically in individual, multiple, overlapping, and non-overlapping setting. The combination of hyper-blocks with linguistic description of visual patterns is presented too. It is shown that Hyper models generalize decision trees. The Hyper algorithm was tested on the benchmark data from UCI ML repository. It allowed discovering pure and mixed HBs with all data and then with 10-fold cross validation. The links between hyper-blocks, dimension reduction and visualization are established. Major benefits of hyper-block technology and the Hyper algorithm are in their ability to discover and observe hyper-blocks by end-users including side by side visualizations making patterns visible for all classes. Another advantage of sets of HBs relative to the decision trees is the ability to avoid both data overgeneralization and overfitting.
