摘要:

如今,许多用户共享的通信网络是一个普遍的挑战。在本文中,我们同时解决这一挑战的几个方面:学习未知的随机网络特性,与其他用户共享资源,同时保持协调开销最小。所提出的解决方案将多臂Bandit学习与基于信号的轻量级协调方案相结合,并确保收敛到稳定的资源分配。我们的工作考虑两种情况下的单用户级算法:一个未知的固定数量的用户,和一个动态的用户数。分析性能保证,证明收敛到稳定的婚姻配置,这两种设置。这些算法是基于全系统的角度设计的,而不是专注于单个用户的福利。因此,确保了最大的资源利用率。一个广泛的实验分析,包括收敛到一个稳定的配置,以及奖励最大化。实验进行了广泛的设置,展示了我们的方法比现有的国家的最先进的方法的优势。

英文摘要:

Communication networks shared by many users are a widespread challenge nowadays. In this paper we address several aspects of this challenge simultaneously: learning unknown stochastic network characteristics, sharing resources with other users while keeping coordination overhead to a minimum. The proposed solution combines Multi-Armed Bandit learning with a lightweight signalling-based coordination scheme, and ensures convergence to a stable allocation of resources. Our work considers single-user level algorithms for two scenarios: an unknown fixed number of users, and a dynamic number of users. Analytic performance guarantees, proving convergence to stable marriage configurations, are presented for both setups. The algorithms are designed based on a system-wide perspective, rather than focusing on single user welfare. Thus, maximal resource utilization is ensured. An extensive experimental analysis covers convergence to a stable configuration as well as reward maximization. Experiments are carried out over a wide range of setups, demonstrating the advantages of our approach over existing state-of-the-art methods.
