Fig. 1From: Biological knowledge-slanted random forest approach for the classification of calcified aortic valve stenosisScheme of the Knowledge-slanted random forest for classification tasks. A) The first step is to construct the modified selection probability using the random walk with restart (RWR) over the protein-protein interaction network. B) In the second step, a Knowledge-slanted random forest is run using the modified selection probability for each geneBack to article page
