中文简介:
本文描述了Airbnb的定价策略模型,Airbnb是一个分享房屋和体验的在线市场。价格优化的目标是帮助在Airbnb上分享房屋的房主为他们的房源设定最优价格。与传统的定价问题(定价策略被应用于大量相同的产品)不同,Airbnb上没有“相同”的产品,因为我们平台上的每一个列表都为我们的客人提供了独特的价值和体验。Airbnb房源的独特特性使得应用传统的收益最大化定价策略时很难估算出准确的需求曲线。 我们的定价体系由三个部分组成。首先,用二元分类模型预测每个上市夜的预订概率。其次,回归模型预测每个上市夜的最优价格,其中使用定制损失函数来指导学习。最后,我们在第二个模型的输出上应用额外的个性化逻辑,以生成最终的价格建议。在本文中,我们着重描述了我们的定价系统的第二阶段的回归模型。我们还描述了一组用于离线评估的新指标。建议的定价策略已经在生产中部署,以支持Airbnb上的价格提示和智能定价工具。在线A/B测试结果证明了所提策略模型的有效性。
课程简介: This paper describes the pricing strategy model deployed at Airbnb, an online marketplace for sharing home and experience. The goal of price optimization is to help hosts who share their homes on Airbnb set the optimal price for their listings. In contrast to conventional pricing problems, where pricing strategies are applied to a large quantity of identical products, there are no “identical” products on Airbnb, because each listing on our platform offers unique values and experiences to our guests. The unique nature of Airbnb listings makes it very difficult to estimate an accurate demand curve that’s required to apply conventional revenue maximization pricing strategies. Our pricing system consists of three components. First, a binary classification model predicts the booking probability of each listing-night. Second, a regression model predicts the optimal price for each listing-night, in which a customized loss function is used to guide the learning. Finally, we apply additional personalization logic on top of the output from the second model to generate the final price suggestions. In this paper, we focus on describing the regression model in the second stage of our pricing system. We also describe a novel set of metrics for offline evaluation. The proposed pricing strategy has been deployed in production to power the Price Tips and Smart Pricing tool on Airbnb. Online A/B testing results demonstrate the effectiveness of the proposed strategy model.
