Rapid community learning for predictive models of medical knowledge

摘要

A predictive model of medical knowledge is trained (42, 48) from patient data of multiple different medical centers (14). The predictive model is machine learnt from routine patient data from multiple medical centers (14). Distributed learning avoids transfer of the patient data from any of the medical centers (14). Each medical center (14) trains (42) the predictive model from the local patient data. The learned statistics, and not patient data, are transmitted (44) to a central server (12). The central server (12) reconciles (48) the statistics and proposes (52) new statistics to each of the local medical centers. In an iterative approach, the predictive model is developed without transfer of patient data but with statistics responsive to patient data available from multiple medical centers (14). To assure comfort with the process, the transmitted statistics may be in a human readable format.
