Figure 2From: Integration of multiple data sources to prioritize candidate genes using discounted rating systemThe procedure of leave one out cross validation. For the investigated disease family, one disease gene and 99 nearest genes form the test set. The other disease genes are training genes, used as source nodes of RWR (random walk with restart) algorithm. Test genes are ranked by the RWR algorithm. Ideally, the held-out gene should be ranked top.Back to article page
