Abstract

Clustering by document concepts is a powerful way ofretrieving information from a large number of documents.This task in general does not make any assumption on thedata distribution. In this paper, for this task we propose anew competitive Self-Organising (SOM) model, namelythe Dynamic Adaptive Self-Organising Hybrid model(DASH). The features of DASH are a dynamic structure,hierarchical clustering, non-stationary data learning andparameter self-adjustment. All features are data-oriented:DASH adjusts its behaviour not only by modifying itsparameters but also by an adaptive structure. Thehierarchical growing architecture is a useful facility forsuch a competitive neural model which is designed fortext clustering. In this paper, we have presented a newtype of self-organising dynamic growing neural networkwhich can deal with the non-uniform data distributionand the non-stationary data sets and represent the innerdata structure by a hierarchical view.
