A method of classifying a plurality of elements, such as genes, an associated system and an associated computer-read-able storage medium. Similarity values for pairs of elements are measured. For example, in the case of genes, gene expression fingerprints are measured, and the similarity values are computed from the fingerprints. A graph is constructed such that each vertex of the graph corresponds to a respective element. Each edge of the graph is assigned a superbinary weight that is based on the corresponding similarity value. The graph is partitioned into kernels, and the kernels are merged into clusters. Preferably, the superbinary weights are based on the similarity values according to a probabilistic model. The system of the present invention includes an apparatus for measuring the similarity values, a memory for storing the similarity values, and a proccesor for implementing the method of the present invention. The storage medium of the present invention includes computer readable code in which the method of the present invention is encoded.
