Federated learning (FL) is a machine learning setting where many clients (e.g. mobile devices or whole organizations) collaboratively train a model under the orchestration of a central server (e.g. service provider), while keeping the training data decentralized. FL embodies the principles of focused data collection and minimization, and can mitigate many of the systemic privacy risks and costs resulting from traditional, centralized machine learning and data science approaches. Motivated by the explosive growth in FL research, this paper discusses recent advances and presents an extensive collection of open problems and challenges.

联邦学习（Federated Learning）是一种新兴的人工智能基础技术，在 2016 年由谷歌最先提出，原本用于解决安卓手机终端用户在本地更新模型的问题，其设计目标是在保障大数据交换时的信息安全、保护终端数据和个人数据隐私、保证合法合规的前提下，在多参与方或多计算结点之间开展高效率的机器学习。其中，联邦学习可使用的机器学习算法不局限于神经网络，还包括随机森林等重要算法。联邦学习有望成为下一代人工智能协同算法和协作网络的基础。
