The challenge of modeling Decision support systems for medical problems using Fuzzy Cognitive Maps: An overview

The difficult and challenging problem of Medical Diagnosis using Decision Support Systems (DSS) is addressed from a system´s point of view. The novel approach of Fuzzy Cognitive Maps (FCMs) as a computational modelling method has been used to tackle problem of DSS for medical problems. The FCM approach is used to address the Medical Decision Analysis and compare it with Decision Trees algorithms. Two medical problems, the bladder tumor grading and Radiotherapy are analyzed and studied using the proposed FCM approach. Simulation results been obtained previously are presented and discussed. The important contributions that have been made by using FCM in a number of medical applications are briefly discussed and future research directions are provided for the clinical use of the FCM methodology.
