Research of electronic medical record data mining method based on variable precision rough set

摘要

With the appearance of electronic medical records(E_MRs), it is possible to acquire and retrieve the medical and diag_nosis information. A variable precision rough set(VPRS)-based approach for electronic medical record data mining is proposed in this paper, the method overcomes the limitation of rough sets, inducting error accuracy to the model, improving fault tolerance. Finally the data mining experiment of electronic medical record is designed, the result shows that it is better to assist doctor to clinical diagnosis and treatment.
