“…The different factors such as instability in the patient, insufficient time for collecting diagnostic data, diagnostic error along with the high volume of data, the intricacy and uncertainty in the disease diagnosis process has been increased. In contrast to the real value, the fuzzy logic techniques like fuzzy expert system, fuzzy set theory, fuzzy classification, fuzzy cognitive map, rule-based fuzzy logic, weighted fuzzy rule assist along with adaptive neuro-fuzzy inference system in detecting the degree of membership for different psychiatric disorders [37]. In simple terms, for handling imprecise and incomplete data, the use of fuzzy logic, rough set and stochastic reasoning can be an added advantage.…”
