It has been a bottleneck problem to establish a knowledge database in expert system of disease diagnosis. The quality of knowledge database has an impact not only on subsequent consequence but also on diagnostic precision. This paper proposes an improved method of rough sets, and then the method is applied into rheumatic mitral stenosis disease diagnosis. Abstracting rules based on rough set theory...
A number of calculators that compute the risk of atherosclerosis has been developed and made available on the Internet. They all are based on computing weighted sum of risk factors. We propose instead to use more flexible rule-based approach to estimate this risk. The used rules were created using machine learning methods and further refined by domain expert. Using our rule-based expert system NEST,...
The septicemia expert system (SES), an expert system designed for diagnosis of pathogens (DIAGSES) and antibiotics prescription, is discussed. SES is provided with a large clinical database (SES-DB), which includes extensive information about septicemia. A link between the SES-DB and SES was designed to facilitate the evaluation of SES. It showed the possibility of improving DIAGSES efficiency. Statistical...
The difficulties of computerized analysis and measurement of the ECG (electrocardiogram) during exercise testing are compounded by the increases in noise and signal complexity at higher workloads and heart rates. By incorporating a hybrid expert-system structure in the analysis approach, information from the serial exercise ECG records are submitted to statistical and heuristic decision-logic to improve...
