From: Network-based de-noising improves prediction from microarray data
Improvement of prediction by noise reduction with various combinations of networks. The upper figure plots the results of PCR, the bottom of kNN. The mean correlation coefficients of prediction for 1,427 drugs before and after the off-subspace noise reduction are shown. Abbreviations are Corr: correlation coefficient for gene expressions; Sim: sequence similarity; GO: gene ontology; PPi: protein-protein interaction; All: Corr+Similarity+GO+PPi; Corr&Drug: input de-noising only via Corr and output de-noising; and All&Drug: input de-noising using All and output de-noising.
