Federated learning and Digital Health
History In 2016, McMahan and colleagues at Google (McMahan et al., 2017) published a paper on a decentralized approach to machine learning and coined the term “federated learning” to describe a process in which model parameters are aggregated from individual clients that run local training sets, while leaving individual data on local devices.
Current challenges of Data Interoperability Data interoperability has been one of the biggest challenges for modern health care. Health care data is highly personal and private and this necessitates the data to be secure. However, health care data must be easily accessible and interoperable to trusted parties as the inability of health care data to be easily moved from one place to another can cause great harm.
Federated Learning and Data Interoperability
Federated learning principles can be used to address challenges in data interoperability and provide a higher quality of care. At the institutional level, federated learning can be used to pool data from multiple institutions to capture a greater diversity of patients from different demographics and locations. Consequently, localized biases can be mitigated and provide a greater sensitivity to rare diseases (Rieke et al., 2020). Federated learning has been used to find patient similarity, and predict mortality and hospital stay time (Huang et al., 2019; Lee et al., 2018). Recently, federated learning across nations was used to detect chest CT abnormalities in COVID-19 patients and was found to perform better than training at local sites (Dou et al., 2021).
