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


ABSTRACT: 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.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.dargenio@bmsr.usc.eduSupplementary material is available at Bioinformatics online.
