一种基于学习的混合决策框架:用于具有用户离开检测的匹配系统 / A Learning-Based Hybrid Decision Framework for Matching Systems with User Departure Detection
1️⃣ 一句话总结
这篇论文提出了一种智能混合匹配框架,它通过学习用户离开模式动态调整匹配时机,在减少等待时间的同时,只牺牲少量匹配效率,从而在即时匹配和延迟匹配之间找到灵活平衡。
In matching markets such as kidney exchanges and freight exchanges, delayed matching has been shown to improve overall market efficiency. The benefits of delay are highly sensitive to participants' sojourn times and departure behavior, and delaying matches can impose significant costs, including longer waiting times and increased market congestion. These competing effects make fixed matching policies inherently inflexible in dynamic environments. We propose a learning-based Hybrid framework that adaptively combines immediate and delayed matching. The framework continuously collects data on user departures over time, estimates the underlying departure distribution via regression, and determines whether to delay matching in the subsequent period based on a decision threshold that governs the system's tolerance for matching efficiency loss. The proposed framework can substantially reduce waiting times and congestion while sacrificing only a limited amount of matching efficiency. By dynamically adjusting its matching strategy, the Hybrid framework enables system performance to flexibly interpolate between purely greedy and purely patient policies, offering a robust and adaptive alternative to static matching mechanisms.
