论文摘要

在过去的几年中,机器学习领域(ML)已取得了重大进步,以解决无线网络中的资源管理,干扰管理,自治和决策。传统的ML方法取决于集中方法,在中央服务器上收集数据以进行培训。但是,这种方法在保留设备的数据隐私方面构成了挑战。为了解决这个问题,联合学习(FL)已成为一种有效的解决方案,允许边缘设备在不损害数据隐私的情况下协作训练ML模型。在FL中,本地数据集未共享,重点是学习涉及所有设备的特定任务的全局模型。但是,FL在将模型调整为具有不同数据分布的设备方面存在局限性。在这种情况下,考虑了元学习,因为它只能使用少数数据示例将学习模型适应不同的数据分布。在本教程中,我们介绍了FL,元学习和联合元学习(FEDMETA)的全面综述。与其他教程论文不同,我们的目标是探讨如何设计,优化和进化的FL,元学习和FedMeta方法以及它们在无线网络上的应用。我们还分析了这些学习算法之间的关系,并研究了它们在现实世界应用中的优势和缺点。

Over the past few years, significant advancements have been made in the field of machine learning (ML) to address resource management, interference management, autonomy, and decision-making in wireless networks. Traditional ML approaches rely on centralized methods, where data is collected at a central server for training. However, this approach poses a challenge in terms of preserving the data privacy of devices. To address this issue, federated learning (FL) has emerged as an effective solution that allows edge devices to collaboratively train ML models without compromising data privacy. In FL, local datasets are not shared, and the focus is on learning a global model for a specific task involving all devices. However, FL has limitations when it comes to adapting the model to devices with different data distributions. In such cases, meta learning is considered, as it enables the adaptation of learning models to different data distributions using only a few data samples. In this tutorial, we present a comprehensive review of FL, meta learning, and federated meta learning (FedMeta). Unlike other tutorial papers, our objective is to explore how FL, meta learning, and FedMeta methodologies can be designed, optimized, and evolved, and their applications over wireless networks. We also analyze the relationships among these learning algorithms and examine their advantages and disadvantages in real-world applications.
