美国产生的食物浪费数量惊人，无论是经济成本还是环境副作用都很昂贵。过剩的粮食本来可以用来养活面临粮食不安全的人们，但却被丢弃并填埋。机构、大学和非营利组织已经注意到这个问题，并开始采取行动减少剩余的食物浪费，通常是将其重新定向到食物银行和其他组织，或者让学生运输或食用这些食物。这些方法带来了一些挑战，如交通、志愿者的可用性以及缺乏对有需要的人的优先考虑。在本文中，我们介绍了PittGrub，一个通知系统，可以智能地选择邀请用户参加有剩余食物的活动。匹兹堡大学发明PittGrub是为了帮助减少食物浪费。我们使用强化学习来确定发送多少通知，并使用评估模型来确定通知中的优先级。我们的目标是建立一个系统，优先为有需要的学生提供食物，同时消除食物浪费，保持通知的公平分发。据我们所知，PittGrub在消除剩余食物浪费的同时努力实现社会公益的方法是独一无二的。我们将我们提出的技术与模拟数据集上的多个基线进行比较，以证明其有效性。各种算法的实验结果显示，它们有望消除食物浪费，同时帮助那些面临粮食不安全的人，并公平对待用户。我们的原型目前处于测试阶段，很快就会进入苹果应用商店。
The amount of food waste generated by the U.S. is staggering, both expensive in economic cost and environmental side effects. Surplus food, which could be used to feed people facing food insecurity, is instead discarded and placed in landfills. Institutions, universities, and non-profits have noticed this issue and are beginning to take action to reduce surplus food waste, typically by redirecting it to food banks and other organizations or having students transport or eat the food. These approaches present challenges such as transportation, volunteer availability, and lack of prioritization of those in need. In this paper, we introduce PittGrub, a notification system to intelligently select users to invite to events that have leftover food. PittGrub was invented to help reduce food waste at the University of Pittsburgh. We use reinforcement learning to determine how many notifications to send out and a valuation model to determine whom to prioritize in the notifications. Our goal is to produce a system that prioritizes feeding students in need while simultaneously eliminating food waste and maintaining a fair distribution of notifications. As far as we are aware, PittGrub is unique in its approach to eliminating surplus food waste while striving for social good. We compare our proposed techniques to multiple baselines on simulated datasets to demonstrate effectiveness. Experimental results among various algorithms show promise in eliminating food waste while helping those facing food insecurity and treating users fairly. Our prototype is currently in beta and coming soon to the Apple App Store.
