Abstract:
This paper presents a real world application where intelligent techniques have given promising results when statistical
methods fail. Here we have considered the domain of Ayurvedic classification of individuals. Ayurvedic classification
on individuals is based on analysis of a questionnaire. The questionnaire has been used over many years without any
research into its improvement. So, classification using this method is still vague and subjective. An intelligent hybrid
system has been developed to recognize human constituents. The system consists of modules using two intelligent
techniques, namely, Fuzzy logic and Expert system.
The statistical analysis on questionnaire of pilot study shows that principal component (PC) are not significant to
consider. However, according to intelligent system developed, there is a significant difference between what we
conclude with PC analysis and without PC analysis, provided that intelligent technique of Fuzzy logic is used. This is
an interesting result that shows limitation of statistical techniques and how intelligent systems can be used for
improving decision making.
