移动物联网联邦成员学习模型的公平自主共享

Fair and autonomous sharing of federate learning models in mobile Internet of Things

摘要:

联邦成员学习可以进行机器学习以及保护相应端上的自有训练数据的隐私,而不必上传到中央可信数据聚合服务器。在移动场景中,集中式可信服务器可能不存在,并且即使存在,延迟也将是不可管理的,例如,智能驾驶汽车因此,具有隐私感知的边缘移动联邦成员学习受到越来越多的关注。然后,它提出了一个问题-在移动终端上训练数据以获得学习模型之后,如何在其他人之间共享模型参数以创建更准确和鲁棒的累积最终模型。这种模型共享面临若干挑战,例如,共享必须在没有第三方可信方的情况下(自主地)进行,并且共享必须是公平的,因为模型训练(通过训练数据)是有价值的。为了解决上述挑战,我们提出了一个智能合约和IPFS(星际文件系统)的模型共享协议和算法来解决这些挑战。所提出的协议不依赖于可信的第三方,其中个人学习的模型被共享/存储在相应的端。通过广泛的实验进行,所提出的协议的三个主要步骤进行评估。三个步骤的平均执行时间分别为0.059s、0.060s和0.032s,证明了该算法的有效性。

英文摘要:

Federate learning can conduct machine learning as well as protect the privacy of self-owned training data on corresponding ends, instead of having to upload to a central trusted data aggregation server. In mobile scenarios, a centralized trusted server may not be existing, and even though it exists, the delay will not be manageable, e.g., smart driving cars. Thus, mobile federate learning at the edge with privacy-awareness is attracted more and more attentions. It then imposes a problem - after data are trained on a mobile terminal to obtain a learned model, how to share the model parameters among others to create more accurate and robust accumulative final model. This kind of model sharing confronts several challenges, e.g., the sharing must be conducted without a third trusted party (autonomously), and the sharing must be fair as model training (by training data)is valuable. To tackle the above challenges, we propose a smart contract and IPFS (Inter-Planetary File System) based model sharing protocol and algorithms to address the challenges. The proposed protocol does not rely on a trusted third party, where individual-learned models are shared/stored in corresponding ends. Conducted through extensive experiments, three main steps of the proposed protocol are evaluated. The average executive time of the three steps are 0.059s, 0.060s and 0.032s, demonstrating its efficiency.
