A GH-SOM optimization with SOM labelling and dunn index
2011 11th International Conference on Hybrid Intelligent Systems (HIS), 2011Clustering is an unsupervised classification method that divides a data set in groups, where the elements of a group have similar characteristics to each other. A well-known clustering method is the Growing Hierarchical Self-Organizing Map (GH-SOM), that improves the results of an ordinary SOM by controlling the number of neurons generated.

A behavioral study of learning in standard SOM and in S-SOM
2009 International Joint Conference on Neural Networks, 2009In this paper we establish the completion of a previously published work, in part by the same authors, in which we proposed a novel learning algorithm involving Self Organizing Map's (SOM) internal structure in the learning process. We present a statistical and a behavioral study of our proposed solution, and confirm its results on a breast cancer ...

Tekst som anledning, dialog som data, kontekst som forstyrrer
2010This paper sets off to discuss the meaning of context in collaborative knowledge production. The discussion will be unfolded in relation to an experiment of moving a concrete text from one collective context of analysis to another. Doing the unthinkable: Moving a text out of context to find out how context informs focus of analysis and explore the ...

Vores sam-fund er i stigende grad blevet et samfund, hvor alderdommen anses som et problem og en byrde både for den enkelte og for samfundet.
