机器学习模型中的个体解释:贫困估计的案例研究

Individual Explanations in Machine Learning Models: A Case Study on Poverty Estimation

摘要:

机器学习方法正越来越多地应用于敏感的社会环境中,在这些环境中,决策会影响人类生活。因此,有必要建立能力,为模型的预测提供易于解释的解释。最近在学术文献中,已经提出了大量的解释方法。不幸的是,据我们所知,关于机器学习从业者在现实世界中应用它们时最常面临的挑战,几乎没有记录。例如,一个典型的过程,如特征工程,可以使一些方法不再适用。本案例研究有两个主要目标。首先,揭露这些挑战,以及它们如何影响相关和新颖的解释方法的使用。第二,提出一套战略,以减轻在相关应用领域-贫困估计及其用于优先获得社会政策-实施解释方法时所面临的挑战。

英文摘要:

Machine learning methods are being increasingly applied in sensitive societal contexts, where decisions impact human lives. Hence it has become necessary to build capabilities for providing easily-interpretable explanations of models' predictions. Recently in academic literature, a vast number of explanations methods have been proposed. Unfortunately, to our knowledge, little has been documented about the challenges machine learning practitioners most often face when applying them in real-world scenarios. For example, a typical procedure such as feature engineering can make some methodologies no longer applicable. The present case study has two main objectives. First, to expose these challenges and how they affect the use of relevant and novel explanations methods. And second, to present a set of strategies that mitigate such challenges, as faced when implementing explanation methods in a relevant application domain -- poverty estimation and its use for prioritizing access to social policies.
