心电图(ECG)记录是敏感的生物医学数据,这限制了医院和可穿戴设备共享原始信号以进行集中式模型训练的能力。联邦学习通过在各自数据源保留原始生物信号数据的同时实现协作式模型训练,解决了这一实际隐私约束。然而,由于客户端样本有限、心律失常标签不平衡以及客户端间数据非独立同分布(non-IID),联邦心电图分类仍具挑战性。这些约束要求分类器兼具通信效率和对跨客户端分布偏移的鲁棒性。本研究在联邦平均(FedAvg)框架下,针对MIT-BIH数据集的五类心律失常分类和INCART数据集的三类分类,对比评估了混合量子启发式柯尔莫哥洛夫-阿诺尔德网络(HQKAN)与多层感知机(MLP)的性能。在多种客户端配置下,HQKAN在MIT-BIH上提升了多数聚合指标及少数类指标,同时可训练参数减少37.35%,通信成本降低24.89%;在INCART上,其对应减少幅度分别为44.81%和36.41%。这些结果表明,HQKAN为生物信号数据的隐私感知联邦学习提供了一种紧凑、通信高效且鲁棒的替代方案,优于MLP基线模型。
英文摘要
Electrocardiogram (ECG) recordings are sensitive biomedical data, limiting the ability of hospitals and wearable devices to share raw signals for centralized model training. Federated learning addresses this practical privacy constraint by enabling collaborative model training while keeping raw biosignal data at their respective sources. However, federated ECG classification remains challenging due to limited client-side samples, imbalanced arrhythmia labels, and non-independent and identically distributed (non-IID) data across clients. These constraints require classifiers that are both communication-efficient and robust to cross-client distribution shifts. In this work, we evaluate a hybrid quantum-inspired Kolmogorov-Arnold network (HQKAN) against a multilayer perceptron (MLP) for five-class arrhythmia classification on the MIT-BIH dataset and three-class classification on the INCART dataset under federated averaging (FedAvg). Across multiple client configurations, HQKAN improves most aggregate and minority-class metrics while using 37.35% fewer trainable parameters and reducing communication cost by 24.89% on MIT-BIH; on INCART, it achieves corresponding reductions of 44.81% and 36.41%. These results indicate that HQKAN offers a compact, communication-efficient and robust alternative to the MLP baseline for privacy-aware federated learning on biosignal data.
