The goal of the proposed methods is to addressclustering problems, in which the optimal clustering method is unknown. Addi-tionally, by means of pairwise linkage constraints, it is possible to aggregate extrainformation to the clustering framework.Part I investigates the concept of ensemble clustering. It presents a comprehen-sive review of the state of the art in ensemble It follows by discussingthe impact of the ensemble variability in the nal consensual result. Visualizationof ensemble variability based on multidimensional scaling is also a topic addressedin this part. A software which is able to perform ensemble clustering using vari-ous existing consensus functions is also introduced.
