Fig. 3From: Grace-AKO: a novel and stable knockoff filter for variable selection incorporating gene network structuresFlowchart of Grace-AKO. These two procedures are differentiated by colors, in which the green one is Grace and the blue one is Grace-AKO. First, we encode the Laplacian matrix account for the network structure and sample model-X knockoffs. Second, we compute the feature statistics LCDs. Third, we aggregate the LCDs to get AGCs. Fourth, we select the variables whose AGCs satisfy the requirementsBack to article page
