Fuzzy min–max neural networks for categorical data: application to missing data imputation

Pilar Rey-del-Castillo, Jesús Cardeñosa
2011 Neural computing & applications (Print)  
The micro data-the set of the respondents' individual answers to the questions-of this type of poll are especially suited for evaluating the method since they include a large number of numerical and categorical  ...  The usual way of dealing with this type of variables is to replace the categorical by numerical values and treat them as if they were continuously valued.  ...  The next step is to classify the point as the category corresponding to the class with the highest degree of membership.  ...
