Competitive Fuzzy Cognitive Maps Combined with Case Based Reasoning for Medical Decision Support

This paper extends our previous work on Competitive Fuzzy Cognitive Maps for Medical Decision Support Systems by enhancing them with Case Based Reasoning Methods. The synergy of these methodologies is accomplished with a novel algorithm that leads to more dependable Advanced Medical Decision Support Systems for situations where the decisions are not clearly distinct. The model proposed and developed here is applied successfully for two paradigms of decision support. The first one is a differential diagnosis example from the speech pathology area for the diagnosis of language impairments and the second one is a treatment planning example from external beam radiation therapy.
