摘要:

在数据科学中,使用合成数据进行方法开发、特征选择和特征工程有着悠久的历史。我们目前对合成数据的兴趣来自于最近对可解释性的研究。今天的数据集通常更大,更复杂-需要更少的可解释模型。在\textit{post hoc}可解释性的设置中,没有用于解释的真值。受最近解释图像分类器提供真值的工作的启发,我们提出了一个类似的解决方案,表格数据。使用copula,数据集所需统计属性的简明规范,用户可以使用受控数据集和实验来建立关于可解释性的直觉。目前的能力证明了三个用例:一维逻辑回归,信息特征的相关性的影响,冗余变量的相关性的影响。

英文摘要:

In data science, there is a long history of using synthetic data for method development, feature selection and feature engineering. Our current interest in synthetic data comes from recent work in explainability. Today's datasets are typically larger and more complex - requiring less interpretable models. In the setting of \textit{post hoc} explainability, there is no ground truth for explanations. Inspired by recent work in explaining image classifiers that does provide ground truth, we propose a similar solution for tabular data. Using copulas, a concise specification of the desired statistical properties of a dataset, users can build intuition around explainability using controlled data sets and experimentation. The current capabilities are demonstrated on three use cases: one dimensional logistic regression, impact of correlation from informative features, impact of correlation from redundant variables.
