Prediction of human functional genetic networks from heterogeneous data using RVM-based ensemble learning

Bioinformatics. 2010 Mar 15;26(6):807-13. doi: 10.1093/bioinformatics/btq044. Epub 2010 Feb 4.

Abstract

Motivation: Three major problems confront the construction of a human genetic network from heterogeneous genomics data using kernel-based approaches: definition of a robust gold-standard negative set, large-scale learning and massive missing data values.

Results: The proposed graph-based approach generates a robust GSN for the training process of genetic network construction. The RVM-based ensemble model that combines AdaBoost and reduced-feature yields improved performance on large-scale learning problems with massive missing values in comparison to Naïve Bayes.
