Thesis (Ph.D.)--University of Toronto (Canada), 2005.

Microarray technology allows researchers to monitor expression levels for thousands of genes at once. Scientists are interested in developing techniques that could be used to extract useful information from the data set, for example, distinguishing the genes with similar patterns of expression since they expect the genes in a particular cellular pathway to respond similarly to same environment (co-regulated). Clustering methods are used to partition high dimensional microarray gene expression data into groups such that the genes in a cluster are more similar to each other than genes in different clusters based on their expression levels.

520 $a A new method of clustering known as spectral clustering has recently been introduced by Tritchler et al. (2004). The aim of this thesis is to extend application of spectral clustering and to introduce a new method to estimate number of clusters. Cluster validation techniques are introduced and extensive simulation study carried out to assess the performance of our approach. Moreover, publicly available gene expression data sets were used for illustration purposes.
