Abstract
Machine/deep learning has been widely used for big data analysis in the field of healthcare, but it is still a question to ensure both computation efficiency and data security/confidentiality for the protection of private information. Referring to the data-sharing function of the federated learning (FedL) model, we propose an optimized data-sharing FedL (DSFedL) framework via a data-sharing hub by evaluating an accuracy-privacy loss function. When applied to the derived non-identically and independently distributed (nonIID) datasets simulated from three open-source cardiothoracic databases (i.e., ICBHI, Coswara COVID-19, MIT-BIH Arrhythmia), our optimized DSFedL works efficiently and the results show an optimal outcome of both the accuracy/efficiency and data security/confidentiality management.Clinical Relevance—This provides a proof of concept for using DSFedL in clinical applications, particularly in those settings that require data confidentiality control.Keywords
