Linear programming boosting via column generation (2009)
Ayhan Demiriz, Kristin P. Bennett, Nello Cristianini
Abstract. We examine linear program (LP) approaches to boosting and demonstrate their efficient solution using LPBoost, a column generation based simplex method. We formulate the problem as if all...
Modeling sequence evolution with kernel methods (2007)
Turchi, Marco, Cristianini, Nello
We model the evolution of biological and linguistic sequences by comparing their statistical properties. This comparison is performed by means of efficiently computable kernel functions, that take...
Fast SDP relaxations of graph cut clustering, transduction, and other combinatorial problems (2006)
The rise of convex programming has changed the face of many research fields in recent years, machine learning being one of the ones that benefitted the most. A very recent developement, the...
CAFE: a computational tool for the study of gene family evolution (2006)
De Bie, Tijl, Cristianini, Nello, Demuth, Jeffery P., Hahn, Matthew W.
Summary: We present CAFE (Computational Analysis of gene Family Evolution), a tool for the statistical analysis of the evolution of the size of gene families. It uses a stochastic birth and death...
Estimating the tempo and mode of gene family evolution from comparative genomic data (2005)
Hahn, Matthew W., De Bie, Tijl, Stajich, Jason E., Nguyen, Chi, Cristianini, Nello
Comparison of whole genomes has revealed that changes in the size of gene families among organisms is quite common. However, there are as yet no models of gene family evolution that make it possible...
A statistical framework for genomic data fusion (2004)
Lanckriet, Gert R. G., De Bie, Tijl, Cristianini, Nello, Jordan, Michael I., Noble, William Stafford
Motivation: During the past decade, the new focus on genomics has highlighted a particular challenge: to integrate the different views of the genome that are provided by various types of experimental...

Large margin strategies for machine learning. (2000)
Thesis (Ph. D.)--University of Bristol, 2000.
Furey, Terrence S., Cristianini, Nello, Duffy, Nigel, Bednarski, David W., Schummer, Michèl, Haussler, David
Motivation: DNA microarray experiments generating thousands of gene expression measurements, are being used to gather information from tissue and cell samples regarding gene expression differences...
