基于Meta-强化学习的动态信道接入

Dynamic Channel Access via Meta-Reinforcement Learning

Syracuse University(雪城大学)

Ziyang Lu, M. Cenk Gursoy

摘要:

在本文中,我们通过Meta强化学习来解决动态无线环境中的信道接入问题。频谱是无线通信中的稀缺资源,特别是随着网络中设备数量的急剧增加。最近,受到深度强化学习(DRL)的成功的启发,已经在经由DRL解决无线资源分配问题方面进行了广泛的研究。然而,训练DRL算法通常需要为每个特定任务从环境中收集大量数据,并且如果环境中存在微小变化,则经过良好训练的模型可能会失败。在这项工作中,为了解决这些挑战,我们提出了一个元DRL框架,其中包括模型不可知元学习(MAML)的方法。在建议的框架中,我们训练一个共同的初始化类似的通道选择任务。从初始化,我们表明,只有几个梯度下降需要适应不同的任务从同一分布。我们通过仿真结果证明了性能的改善。

英文摘要:

In this paper, we address the channel access problem in a dynamic wireless environment via meta-reinforcement learning. Spectrum is a scarce resource in wireless communications, especially with the dramatic increase in the number of devices in networks. Recently, inspired by the success of deep reinforcement learning (DRL), extensive studies have been conducted in addressing wireless resource allocation problems via DRL. However, training DRL algorithms usually requires a massive amount of data collected from the environment for each specific task and the well-trained model may fail if there is a small variation in the environment. In this work, in order to address these challenges, we propose a meta-DRL framework that incorporates the method of Model-Agnostic Meta-Learning (MAML). In the proposed framework, we train a common initialization for similar channel selection tasks. From the initialization, we show that only a few gradient descents are required for adapting to different tasks drawn from the same distribution. We demonstrate the performance improvements via simulation results.
