Abstract
An iterative shrinking algorithm has been recently proposed to replace mergebased
agglomerative clustering. In this work, we first extend this idea to the case
where the number of clusters must also be solved. We then integrate the method
within genetic algorithms that uses iterative shrinking for crossover. The
proposed method outperforms all other clustering algorithms we have tested. We
therefore conclude that this method is the best existing clustering algorithm in
terms of minimizing the distortion function value.
1 Introduction
Clustering is an important problem that must often be solved as a part of more
complicated tasks in pattern recognition, image analysis, and other fields of
science and engineering [I, 2, 31. Clustering is also needed for designing a
codebook in vector quantization [4]. Clustering problem is de
