AI总结:

研究用户在时间变化状态下的学习问题,通过设计激励机制使用户真实披露私有信号,减少战略目标与团队目标的差距及激励支付。

摘要:

我们考虑了在用户推荐系统中,具有不对称信息的战略用户如何学习潜在的时间变化状态的问题。用户通过观察关于状态的私人信号,依次决定购买产品,而该产品的价值以 ergodic 方式随时间变化。我们将团队问题 formulation 为一个去中心化随机控制问题的实例,并刻画其最优策略。在战略用户的情况下,我们设计激励机制,使用户披露真实的私人信号,从而使得战略目标与团队目标之间的差距较小,且总体预期的激励支付也较小。

英文摘要:

We consider the problem of how strategic users with asymmetric information can learn an underlying time varying state in a user-recommendation system. Users who observe private signals about the state, sequentially make a decision about buying a product whose value varies with time in an ergodic manner. We formulate the team problem as an instance of decentralized stochastic control problem and characterize its optimal policies. With strategic users, we design incentives such that users reveal their true private signals, so that the gap between the strategic and team objective is small and the overall expected incentive payments are also small.
