Hi, you can modify "LamgSetup.m" and then execute "mcc -m LamgSetup.m" in the Matlab command-line mode. For more details, you can check here: https://www.mathworks.com/help/compiler/mcc.html

No, you need to run "make.m" file first. You can also change the lamg code in lamg/. On Sat, Mar 21, 2020 at 11:43 AM NIRVANA wrote: > Hi, is...

Running "mcc -m LamgSetup.m" should give you binary file. You can check affinity matrix here: lamg/main/+amg/+coarse/CoarseSetAffinityMatrix.m Have you run "make.m" before running "LamgSetup.m"?

Hi Wei, Thanks for your interest! The "Mapping.mtx" file will be automatically obtained after running "lamg" coarsening: https://github.com/cornell-zhang/GraphZoom/blob/5156f86fa22efa853e864553de4225a9122d8062/graphzoom/graphzoom.py#L123-L124 Please refer to this line about how we generate the mapping matrix:...

Hi Wei, Are you using "lamg" coarsening? If so, have you successfully finished the lamg coarsening (there should be a table showing coarsening details printed out)? It would be more...

Hi Wei, The error message shows that the lamg coarsening is not successfully finished (reduction ratio is too small). Thus, the coarsening process is stopped and cannot generate the Mapping.mtx...

I see. We noticed that the "lamg" coarsening would crash on a few datasets. This is because the lamg solver (our matlab code) has some predefined hyperparameters that may be...

Hi Tobias, Thanks for the reply! I mean the graphs that are attacked by PR-BCD (under the poison setting). My gpu memory only has 11G and probably cannot run PR-BCD...

Hi Tobias, I just tried to run the code after following the instruction to install packages, but got a couple of errors below: 1. The package `rgnn_at_scale.helper` is not included....

Hi, For the original sampling algorithm used in our paper, it is based on a numerical solver (LAMG) implemented in Matlab. With that said, we also provide a simplified coarsening...
