VISTA算法可在敌对环境中实现去中心化机器学习

研究人员推出了一种新颖的去中心化机器学习算法VISTA,该算法即使在敌对节点控制多数的情况下也能有效运行。该系统基于激励框架运行,仅奖励相互一致的报告,从而将敌对者转变为理性代理人,在腐败与潜在奖励损失之间进行权衡。VISTA使用优化历史自适应调整其接受阈值,展示了比静态方法更优的收敛性,并保留了与标准SGD相似的渐近收敛特性,而无需诚实多数。 AI

影响 引入了一种鲁棒的去中心化机器学习方法,即使在多数节点恶意的情况下也能运行,有望提高分布式AI系统的安全性和可靠性。

    \mathsf{VISTA}:在对抗者主导环境中的去中心化机器学习

    Decentralized machine learning often relies on outsourcing computations, such as gradient evaluations, to untrusted worker nodes. Existing robust aggregation methods can mitigate malicious behavior under honest-majority assumptions, but may fail when adversaries control a majorit…
