The comparison of different graphs. ((a) and (b)) The PR curves, as well as the precision, recall, and -measure values for the comparison of LNR graph and graph weighted by the Gaussian function with different variances , 5, 10, 15, 20, respectively. We note that the Gaussian weight function with the variance achieves the best performance. In fact, choosing an appropriate parameter is difficult.
