ORDONEZ, CELESTINO; SAAVEDRA, ÁNGELES; ARAUJO, MARÍA  and  GIRALDEZ, EDUARDO. KAOLIN QUALITY DETERMINATION THROUGH AN ALGORITHM BASED ON NON-PARAMETRIC FUZZY LOGIC. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.171, pp.59-64. ISSN 0012-7353.

In this article we describe a new fuzzy supervised classification method that is a modification of the fuzzy pattern-matching multidensity classifier. The latter has been demonstrated to be one of the most effective classifiers for non-convex classes. Implementing a non-parametric density estimator in one stage of the parametric method, we developed a fuzzy non-parametric classifier that manages to avoid some of the problems associated with the parametric method. The method was applied to a mineralogy problem consistingof classifying kaolin samples according to different ceramic quality levels. Our results produced error percentages that were lower than those for the parametric method.

Keywords : classification; fuzzy set; non-parametric fuzzy logic; kaolin quality.
