摘要:

通过利用超快和不规则的时间序列产生的激光延迟反馈,我们以前已经证明了一个可扩展的算法来解决多臂强盗(MAB)的问题,利用时分复用的激光混沌时间序列。尽管该算法检测具有最高奖励期望的手臂,但无法正确识别手臂在奖励期望方面的顺序。在这里,我们提出了一种算法,其中的探索程度是自适应控制的基础上的置信区间,代表的估计精度的奖励期望。我们已经证明了数字,我们的方法确实提高了手臂顺序识别的准确性显着,随着减少对奖励环境的依赖,和总奖励几乎保持与传统的MAB方法相比。本研究适用于订单信息至关重要的部门,例如信息和通信技术的资源有效分配。

英文摘要:

By exploiting ultrafast and irregular time series generated by lasers with delayed feedback, we have previously demonstrated a scalable algorithm to solve multi-armed bandit (MAB) problems utilizing the time-division multiplexing of laser chaos time series. Although the algorithm detects the arm with the highest reward expectation, the correct recognition of the order of arms in terms of reward expectations is not achievable. Here, we present an algorithm where the degree of exploration is adaptively controlled based on confidence intervals that represent the estimation accuracy of reward expectations. We have demonstrated numerically that our approach did improve arm order recognition accuracy significantly, along with reduced dependence on reward environments, and the total reward is almost maintained compared with conventional MAB methods. This study applies to sectors where the order information is critical, such as efficient allocation of resources in information and communications technology.
