报告摘要:Dynamic pricing with demand learning refers to the profit maximization problem where one optimizes the profit by choosing a price and learns the demand at the same time. Traditionally, the cost is fixed and the problem may be formulated as a multi armed bandit problem, which is known to have an O(logT) lower bound on the expected regret, where T is the number of periods. In this paper, we consider the case where the cost changes over periods. Then, the optimal pricing decision becomes a function of the cost. We propose an upper-confidence-bound type of algorithm to solve the problem. When the cost is a continuous random variable, we prove that the expected regret of our proposed algorithm is O((logT)²). When the cost is discrete, surprisingly, we find that the expected regret may be bounded by a constant. This is a joint work with Ying Zhong and Guangwu Liu.
