延迟接受的赛后错误缓解

Post-Match Error Mitigation for Deferred Acceptance

Abraham Gale, Amélie Marian, David M. Pennock

AI总结:

针对延迟接受匹配算法赛后发现的输入错误,提出三种错误场景模型及相应缓解策略,以恢复稳定性并减少对学生的伤害。

摘要:

延迟接受(DA)匹配算法的现实应用有时会出现错误或匹配输入的变化,这些错误或变化只有在算法运行完毕且结果向参与者公布之后才被发现。缓解这些错误的影响是一个与原始匹配不同的问题,因为决策者往往受到已经发出的录取通知的限制。我们为这个新问题提出了模型,以及伴随这些模型的缓解策略。我们探讨了三种不同的错误场景:资源减少、加法错误和减法错误。对于每种错误类型,我们计算了直接受到错误伤害或帮助的学生预期数量,间接受到伤害或帮助的学生数量,以及由于错误而产生合理嫉妒的学生数量。错误缓解策略需要根据管理者的目标来选择,这些目标包括恢复稳定性、避免对任何参与者造成直接伤害,以及将额外负担集中在犯错的学校上。我们提供了错误和缓解策略的实证模拟。

英文摘要:

Real-life applications of deferred-acceptance (DA) matching algorithms sometimes exhibit errors or changes to the matching inputs that are discovered only after the algorithm has been run and the results are announced to participants. Mitigating the effects of these errors is a different problem than the original match since the decision makers are often constrained by the offers they already sent out. We propose models for this new problem, along with mitigation strategies to go with these models. We explore three different error scenarios: resource reduction, additive errors, and subtractive errors. For each error type, we compute the expected number of students directly harmed, or helped, by the error, the number indirectly harmed or helped, and the number of students with justified envy due to the errors. Error mitigation strategies need to be selected based on the goals of the administrator, which include restoring stability, avoiding direct harm to any participant, and focusing the extra burden on the schools that made the error. We provide empirical simulations of the errors and the mitigation strategies.
