摘要:

我们定义并分析了一个多智能体多臂强盗问题,在这个问题中,决策智能体可以在线性观测成本下观测其邻居的选择和回报。邻居由网络图定义,该网络图对系统的固有观测约束进行编码。我们定义了一个与观察相关的成本,这样在每一个实例中,代理人进行观察,它会收到一个恒定的观察遗憾。我们设计了一个抽样算法和一个观察协议,每个代理通过最小化期望累积抽样后悔和期望累积观察后悔来最大化自己的期望累积回报。对于我们提出的协议,我们证明了总累积遗憾是数学界。我们使用数值模拟来验证分析界限的准确性。

英文摘要:

We define and analyze a multi-agent multi-armed bandit problem in which decision-making agents can observe the choices and rewards of their neighbors under a linear observation cost. Neighbors are defined by a network graph that encodes the inherent observation constraints of the system. We define a cost associated with observations such that at every instance an agent makes an observation it receives a constant observation regret. We design a sampling algorithm and an observation protocol for each agent to maximize its own expected cumulative reward through minimizing expected cumulative sampling regret and expected cumulative observation regret. For our proposed protocol, we prove that total cumulative regret is logarithmically bounded. We verify the accuracy of analytical bounds using numerical simulations.
