预测警务算法的种族偏见一直是最近研究的焦点,在霍克斯过程的情况下,反馈回路是可能的,其中有偏见的逮捕通过自我激励被放大,导致热点形成和少数群体的进一步逮捕。在这篇文章中,我们开发了一个惩罚似然法引入公平的犯罪点过程模型。特别是,我们增加了一个惩罚条款的似然函数,鼓励警察巡逻的数量由几个人口群体中的每一个,以该群体在总人口中的代表性成比例。我们将我们的模型应用于印第安纳波利斯的历史犯罪事件数据,并在几个犯罪类别中衡量这两种方法的公平性和准确性。我们表明,公平性可以引入到犯罪的点过程模型,使巡逻水平成比例地匹配人口统计,但在成本的算法的准确性降低。
Racial bias of predictive policing algorithms has been the focus of recent research and, in the case of Hawkes processes, feedback loops are possible where biased arrests are amplified through self-excitation, leading to hotspot formation and further arrests of minority populations. In this article we develop a penalized likelihood approach for introducing fairness into point process models of crime. In particular, we add a penalty term to the likelihood function that encourages the amount of police patrol received by each of several demographic groups to be proportional to the representation of that group in the total population. We apply our model to historical crime incident data in Indianapolis and measure the fairness and accuracy of the two approaches across several crime categories. We show that fairness can be introduced into point process models of crime so that patrol levels proportionally match demographics, though at a cost of reduced accuracy of the algorithms.
