Unlike the evaluation of supervised classifiers, which can be conducted using well-accepted objective measures and procedures, Relative measures try to find the best clustering structure generated by a clustering algorithm using different parameter values. The techniques of global partitioning of the data, such as K-means, partitioning around medoids, various flavors of hierarchical clustering, and self-organized maps [1-4], have provided the initial picture of similarity in the gene expression profiles, Another approach to finding functionally relevant groups of genes is network derivation, which has been popular in the analysis of gene-gene and protein-protein interactions [6-10], and is also applicable to gene expression analysis [11,12].

Cluster analysis, the most widely adopted unsupervised learning process, organizes data objects into groups that have high intra-group similarities and inter-group dissimilarities without a priori information. Finding Groups in Data: An Introduction to Cluster Analysis. Cluster and fuzzy analysis applied to botanical data allowed the classification of six pastoral types and the assessment of the main overlaps between them. Hierarchical cluster analysis allows visualization of high dimensional data and enables pattern recognition and identification of physiologic patient states.

Because the clustering method failed to separate the patient data into groups by obvious traditional physiological definitions these results confirm our hypothesis that clustering would find meaningful patterns of data that were otherwise impossible to physiologically discern or classify using traditional clinical definitions.
