SIGNIFICANCE PARAMETER EXTRACTION METHOD AND ITS CLINICAL DECISION SUPPORT SYSTEM FOR DIFFERENTIAL DIAGNOSIS OF ABDOMINAL DISEASES BASED ON ENTROPY ROUGH APPROXIMATION TECHNOLOGY

摘要

A significance parameter extraction method for differential diagnosis of abnormal diseases based on entropy rough approximation technology, including the steps of: (a) calculating clinical reference values from two different groups of clinical data extracted from a database storing a plurality of clinical data for each check item using an entropy maximization measure; (b) evaluating a clinical difference between the two different groups of clinical data and extracting candidate check items; (c) based on a reference value of a check item calculated from one of the groups of clinical data, converting attribute values of the check item into nominal attribute values; and (d) extracting significance parameters for differential diagnosis from the candidate check items extracted in the step (b).
