摘要:

在在线展示广告中,保证合同和实时竞价(RTB)是出版商销售展示的两种主要方式。对于大型出版商来说,通过担保合同和内部RTB同时销售展示已成为一种流行的选择。一般来说,发布者需要在保证合同和RTB之间导出印象分配策略,以最大化其总体结果(例如,收入和/或印象质量)。然而,导出最优策略不是一项微不足道的任务,例如,该策略应鼓励RTB中的激励兼容性,并解决现实世界应用中的常见挑战,例如不稳定的流量模式(例如,印象量和出价景观变化)。在本文中,我们制定的印象分配作为一个拍卖问题,每个有保证的合同提交虚拟投标的个人印象。有了这个公式,我们得到的最优投标函数的保证合同,从而导致最优的印象分配。为了解决不稳定的交通模式的挑战,并实现最佳的整体结果,我们提出了一个多智能体强化学习方法来调整每个保证合同的出价,这是简单的,收敛效率和可扩展性。在真实数据集上进行的实验证明了该方法的有效性。

英文摘要:

In online display advertising, guaranteed contracts and real-time bidding (RTB) are two major ways to sell impressions for a publisher. For large publishers, simultaneously selling impressions through both guaranteed contracts and in-house RTB has become a popular choice. Generally speaking, a publisher needs to derive an impression allocation strategy between guaranteed contracts and RTB to maximize its overall outcome (e.g., revenue and/or impression quality). However, deriving the optimal strategy is not a trivial task, e.g., the strategy should encourage incentive compatibility in RTB and tackle common challenges in real-world applications such as unstable traffic patterns (e.g., impression volume and bid landscape changing). In this paper, we formulate impression allocation as an auction problem where each guaranteed contract submits virtual bids for individual impressions. With this formulation, we derive the optimal bidding functions for the guaranteed contracts, which result in the optimal impression allocation. In order to address the unstable traffic pattern challenge and achieve the optimal overall outcome, we propose a multi-agent reinforcement learning method to adjust the bids from each guaranteed contract, which is simple, converging efficiently and scalable. The experiments conducted on real-world datasets demonstrate the effectiveness of our method.
