By leveraging deep learning based technologies, the data-driven based approaches have reached great success with the rapid increase of data generated of Industrial Indernet of Things(IIot). However, security and privacy concerns are obstacles for data providers in many sensitive data-driven industrial scenarios, such as healthcare and auto-driving. Many Federated Learning(FL) approaches have been proposed with DNNs for IIoT applications, these works still suffer from low usability of data due to data incompleteness, low quality, insufficient quantity, sensitivity, etc. Therefore, we propose a ring-topogy based decentralized federated learning(RDFL) scheme for Deep Generative Models(DGMs), where DGMs is a promising solution for solving the aforementioned data usability issues. Compare with existing IIoT FL works, our RDFL schemes provides communication efficiency and maintain training performance to boost DGMs in target IIoT tasks. A novel ring FL topology as well as a map-reduce based synchronizing method are designed in the proposed RDFL to improve decentralized FL performance and bandwidth utilization. In addition, InterPlanetary File System(IPFS) is introduced to further improve communication efficiency and FL security. Extensive experiments have been taken to demonstate the superiority of RDFL with either independent and identically distributed(IID) datasets or non-independent and identically distributed(Non-IID) datasets.

The Effect of Training Parameters and Mechanisms on Decentralized Federated Learning based on MNIST Dataset
Georgia Institute of Technology（佐治亚理工学院）
联邦学习是一种适合在分散数据上训练模型的算法，但对中央“服务器”节点的要求是一个瓶颈。在本文中，我们首先介绍了分散式联邦学习（DFL）的概念。然后，我们在不同的设置上进行各种实验，例如改变模型聚合频率，从独立同分布（IID）数据集分区切换到部分全局共享的非IID分区，在客户端之间使用不同的优化方法，以及将模型分解为部分共享的片段。所有实验都在MNIST手写数字数据集上运行。我们观察到，这些改变的训练程序通常是健壮的，尽管不是最佳的。当模型权重之间的方差太大时，我们也观察到训练失败。开源实验代码可通过GitHub \footnote{Code was uploaded at \url{https://github.com/zhzhang2018/DecentralizedFL}}访问。

Decentralized Federated Learning: Balancing Communication and Computing Costs
分散式随机梯度下降（SGD）是分散式联邦学习（DFL）的驱动引擎。分散式SGD的性能受到节点间通信和本地更新的共同影响。在本文中，我们提出了一个通用的DFL框架，它实现了多个本地更新和多个节点间的通信周期，以达到通信效率和模型共识之间的平衡。它可以提供一个通用的去中心化SGD分析框架。我们为所提出的DFL算法建立了强收敛保证，而无需假设凸目标。DFL的收敛速度可以被优化，以实现在有限的资源下的通信和计算成本的平衡。为了提高DFL的通信效率，将压缩通信作为一种新的方案引入到DFL中，命名为DFL with compressed communication（C-DFL）。建议的C-DFL表现出线性收敛的强凸目标。基于MNIST和CIFAR-10数据集的实验结果表明，DFL优于传统的分散SGD方法，并表明C-DFL进一步提高了通信效率。
