[graph-tool] Distribution while fitting weighted SBM

Hi Tiago, I have a short question regarding your implementation of the weighted SBM described here: https://arxiv.org/pdf/1708.01432.pdf https://graph-tool.skewed.de/static/doc/demos/inference/inference.html#edge-weights-and-covariates Does your implementation fit one distribution to sample edge

Dear James, This is a very involved question, and it's a bit difficult to get to the bottom of what you want. I'll start with the last question, which I think can be addressed more directly: Am 03.06.20 um 20:35 schrieb James Ruffle: > Alternatively, do you have any suggestions on how I would ac

Awesome. Thanks for that. One question though. Apart from the edge filter which will make Dijkstra calculation faster, can I also get around storing lots of Inf values in an edgepropertymap ? Suppose, I only want to route along highways. Right now, I would have an edgepropertymap with 98% inf valu

Hi Tiago, thanks, this is already quite helpful. Short follow-up: Our final aim is to sample from the fitted model, also according to the inferred edge covariate distributions between groups. Is this somehow possible with graph-tool? (Up to now we were not able to do this.) Would it, in any ca

Hi Tiago, I tried to register to git.skewed.de using my email, in order to open an issue as discussed in another thread, but never received the confirmation email. Afterward, I tried to login via my github account, but since it has the same email as my first attempt it didnĀ“t let me; fair enough.
