Link Prediction via Sparse Gaussian Graphical Model

Figure 5

Recovery performances of 14 methods on the Taro dataset. The upper left corner is the original matrix; blue points denote links between two corresponding nodes. The red points denote links in the original matrix that were not accurately estimated. The green points denote links in the estimated matrix that do not exist in the original matrix. From left to right, top to bottom, the figures are the recovered matrix by SGGM (, , , and ), CN, Salton, Jaccard, Sørensen, HPI, HDI, LHN, AA, RA, PA, LNBCN, LNBAA, and LNBRA, respectively.
