Clinical Medical Test Decision-Making of Liver Disease Using Granular-Ball Rough Set

Liver disease accounts for 4% of all deaths worldwide. Existing research on liver disease with rough set mostly studied from the perspective of clinical diagnosis, but has not yet been studied from the perspective of clinical medical test decision-making. To address the problem, this paper first converts the clinical diagnosis problem of liver disease into the clinical medical test decision-making problem of liver disease. Then the rough set variant of granular-ball rough set can be used to reduce the attributes of clinical medical test decision-making tasks of liver disease. Next, the clinical medical test decision-making problem is simplified to a classification task. Finally, the proposed method is experimentally verified on the processed liver disease dataset.
