A Study of Clustering Methods Using Visual Data

Priit Danelson
Cluster analysis is a widely used data analysis technique that can be applied by using sev-eral different algorithms. This thesis aims to give an overview of the working principles and specifics of the three most commonly used cluster analysis methods by applying hier-archical clustering, k-means clustering and self-organizing map algorithms on sample data. In addition to the description of working principles of the clustering algorithms, there is also a description of how the script used for applying the clustering methods is implement-ed and an explanation for why visual data or pictures are chosen as the sample data. The thesis also includes an analysis of the clustering results produced by the script.
