Use and Development of Matrix Factorisation Techniques in the Field of Brain Imaging

Pearce, Matthew CraigUniversity of Cambridge2018

… for all subjects in a dataset, including dimension estimation and reduction. This results in uncertainty information being carried coherently through the analysis. A computationally efficient approach to correlated multivariate normal distributions is set out. This enables spatial …

Computational Dissection of Composite Molecular Signatures and Transcriptional Modules

Gong, TingVirginia Tech2009

… a novel stability analysis approach for proper dimension estimation. Experimental results showed that the gene modules identified by the nICA approach appear to be significantly enriched in functional annotations in terms of gene ontology (GO) categories. The third part of the dissertation moves …
