Classification rules are an important tool for discovering knowledge from databases. Integrating fuzzy logic algorithms into databases allows us to reduce uncertainty which is connected with data in databases and to increase discovered knowledge's accuracy. In this paper, we analyze some possible variants of making classification rules from a given fuzzy(More)
About 50% of the patients diagnosed with heart failure die within four years. At the same time, a rise in home telemonitoring of these patients can be observed. For its successful deployment, predicting if a heart failure patient could die within a certain period of time is an important task. An investigation of an alternating decision tree employed for(More)
Cardiovascular decision support is one area of increasing research interest. Ongoing collaborations between clinicians and computer scientists are looking at the application of knowledge discovery in databases to the area of patient diagnosis, based on clinical records. A fuzzy rule-based system for risk estimation of cardiovascular patients is proposed. It(More)
Real-world data containing instances corresponding to patients with otoneurological diseases were explored with fuzzy IF-THEN rule induction. It was based on transformation of a fuzzy decision tree made with using cumulative information estimations as the locally optimal criterion at its nodes. This method uses linguistic variables that allow us to(More)
— Cardiovascular disease is the principal cause of death in most European countries and may have a major negative impact on the patients' functional status, productivity, and quality of life. It seems an automatic decision support system could lower these negative impacts. The current development stage of a patient-centric solution for remote management and(More)
The aim of this study is to improve a fuzzy rule based system that helps to manage heart failure patients in home telemonitoring. The system is intended to give notifications to a decision-making support system and medical experts when there is a possibility of death for a telemonitored patient. The improvement consists in inclusion of a formulated(More)
