AI总结:

针对算法辅助工具常无法改善人类决策的问题,研究基于因果推断潜在结果框架形式化推荐算法设计,引入单调性假设分类人类反应,经招聘实验验证并推导出有限数据下可实现的极小极大最优算法,助力实现人机互补。

摘要:

算法通常是辅助人类决策者而非取而代之。然而,算法的设计与分析往往聚焦于结果预测,并未明确建模其对人类决策的影响。鉴于有实证证据表明算法辅助工具屡屡未能改善人类决策,算法辅助工具的设计与其实际作用之间的这种差异就显得尤为令人担忧。\n在本文中,我们对辅助人类决策者的推荐算法设计进行了形式化处理,且不对推荐如何影响决策施加限制性的事前假设。我们构建了一个算法设计问题,该问题利用因果推断中的potential-outcomes(潜在结果)框架,建模推荐对人类决策者二元治疗选择的影响。在此模型内,我们引入了单调性假设,从而可对人类对算法的反应进行直观分类。在该假设下,我们可以依据人类对算法的依从性,以及在算法不发送推荐时人类会做出的主动决策,来表述人类对算法推荐的反应。\n我们通过一项模拟招聘任务的在线实验,展示了该框架的实用性。我们认为,我们的方法能够解释实验中不同推荐算法的相对性能,且有助于设计实现human-AI complementarity(人机互补)的解决方案。最后,我们利用该方法推导出了minimax optimal(极小极大最优)推荐算法,这类算法可在有限训练数据下通过机器学习实现。

英文摘要:

Algorithms frequently assist, rather than replace, human decision-makers. However, the design and analysis of algorithms often focus on predicting outcomes and do not explicitly model their effect on human decisions. This discrepancy between the design and role of algorithmic assistants becomes particularly concerning in light of empirical evidence that suggests that algorithmic assistants again and again fail to improve human decisions. In this article, we formalize the design of recommendation algorithms that assist human decision-makers without making restrictive ex-ante assumptions about how recommendations affect decisions. We formulate an algorithmic-design problem that leverages the potential-outcomes framework from causal inference to model the effect of recommendations on a human decision-maker's binary treatment choice. Within this model, we introduce a monotonicity assumption that leads to an intuitive classification of human responses to the algorithm. Under this assumption, we can express the human's response to algorithmic recommendations in terms of their compliance with the algorithm and the active decision they would take if the algorithm sends no recommendation. We showcase the utility of our framework using an online experiment that simulates a hiring task. We argue that our approach can make sense of the relative performance of different recommendation algorithms in the experiment and can help design solutions that realize human-AI complementarity. Finally, we leverage our approach to derive minimax optimal recommendation algorithms that can be implemented with machine learning using limited training data.
