The AS 15169 (Google). In the upper left picture, Google’s AS 15169 with a sample of 15% of the nodes coloured in red. The gray nodes correspond to \(\hat{C}_{AS}^{(2)}\), the community found by the Multiresolution Deltacom algorithm using that sample and the AS size. Lower, the detected community, \(\hat{C}_{AS}^{(2)}\). In the upper right picture, all the AS with the frontier nodes coloured in red. The recall score for this AS is \(R_{3}=0.93\).
