摘要: 在多机构联合安全决策场景中,存在隐私保护的约束要求,联邦学习能够为此类场景提供数据不出本地的协同决策方法。但经典的基于联邦学习的决策算法往往采用传统二元决策机制,该机制对不确定问题的处理能力有限。三支决策是一种不确定问题的求解方法,其对不确定性决策对象能进行更为审慎的延迟判定。对此,基于三支决策理论,提出了一种联邦三支安全决策框架(FL-3WSD),该框架在局部规则生成、多源规则融合和目标对象监控3个层面引入三支决策机制,包括参与方侧局部三支规则生成、中央云服务器侧三支多源规则融合以及目标对象三支监控方法。在本框架中,中央云服务器首先向各参与方下发训练模型及相关参数。然后,各参与方利用数据聚类及序贯三支决策方法实现了决策规则提取,并上传至中央云服务器。最后,由中央云服务器进行决策规则汇总、模糊融合,并结合三支决策机制生成全局三支安全决策表,最终用于目标对象的联合判定。实验结果表明,与经典采用二元决策机制的联邦决策方法相比,FL-3WSD框架在决策精度和误判风险控制等方面具有明显优势,体现出较好的科学价值和应用前景。
