Abstract: Data clustering is one of the most important data mining techniques which groups data supported on their similarity. A number of approaches are existing for clustering numerical data and the problem of clustering mixed data is still unresolved. The standard clustering techniques are in general used for numeric data and are not probable to handle mixed data for the reason that of their computational incompetence. The requisite for an enhanced mixed data clustering approach is becoming vital and it is turning out to be a hot research area. By the sort of resolving this issue, Growing Hierarchical Self-Organizing Map (GHSOM) and Extended Attribute-Oriented Induction (EAOI) for clustering mixed data type is previously projected except it does not have any capability to control the growth of the map and in addition the structure of GHSOM is static. To overcoming this issue, a Dynamic Growing Hierarchical Self-Organizing Map (DGHSOM) with EAOI is projected in this paper for handling the mixed data. The main importance of DGHSOM is that it has the ability to grow or modify the structure to represent the application enhanced. The experimentation for the proposed technique is approved with the help of UCI Adult Data Set and Cleve Dataset and it is fond that it is superior to previous approaches based on the number of resultant clusters and outliers with substantial reduction in the processing time. The Clustering error also reduced.
