English(EN) FedDOSE: Federated Learning Framework Decomposing Site Effects for Modeling Brain Dynamic Functional Connectivity

新的联邦学习框架改进了跨站点的脑连接分析

研究人员开发了 FedDOSE,一个新颖的联邦学习框架,旨在改进跨多个站点的脑成像数据中动态功能连接的分析。该框架通过显式分解特定于站点的效应,解决了多站点数据固有的统计异质性挑战。FedDOSE 利用模块化引导的 Tucker 分解来处理高维动态功能连接张量,并采用最优传输和 Procrustes 分析来对齐特定类别的原型。在自闭症谱系障碍和注意力缺陷多动障碍数据集上的实验表明,FedDOSE 在检测方面的性能优于现有方法。 AI

影响 增强了分析复杂的多站点脑成像数据的能力,可能导致对神经系统疾病进行更准确的诊断。

    FedDOSE:用于建模大脑动态功能连接的联邦学习框架分解站点效应

    arXiv:2608.07393v1 Announce Type: new Abstract: Functional Magnetic Resonance Imaging ( fMRI ) data are often pooled into collaborative multi-site consortia, as deep learning models for analyses require large datasets to generalize well. While Federated Learning (FL) offers a pri…
