摘要:

研究了需求模型未知情况下的动态定价问题。在这个问题中,卖方向一群顾客提供价格,并观察每次销售尝试的成功或失败。潜在的需求模型是未知的卖方,可以采取N种可能的形式之一。在本文中,我们表明,这个问题可以制定为一个多臂土匪依赖武器。我们提出了一种基于似然比检验的动态定价策略。我们表明,所提出的政策实现了完全学习,即,它提供了一个有界的遗憾,其中遗憾被定义为相对于具有已知需求模型的情况的收入损失。这与具有独立武器的多臂强盗的对数增长的后悔形成鲜明对比。

英文摘要:

We consider a dynamic pricing problem under unknown demand models. In this problem a seller offers prices to a stream of customers and observes either success or failure in each sale attempt. The underlying demand model is unknown to the seller and can take one of N possible forms. In this paper, we show that this problem can be formulated as a multi-armed bandit with dependent arms. We propose a dynamic pricing policy based on the likelihood ratio test. We show that the proposed policy achieves complete learning, i.e., it offers a bounded regret where regret is defined as the revenue loss with respect to the case with a known demand model. This is in sharp contrast with the logarithmic growing regret in multi-armed bandit with independent arms.
