Thank you, that confirms my suspicion that something strange is going on here. The average description length across 200,000 sweeps appears to be roughly three times that returned by "minimize_nested_blockmodel_dl" so it seems to me like the posterior distribution is not centered around a single partition.
I don't see how you can conclude this from the reason given.
If I have a single peak in the posterior with a likelihood of 1 should I not expect that sampling from the posterior and maximising the posterior likelihood return the same value? Following that, if the average description length obtained by sampling from the posterior is different I must have had other partitions with non-zero probabilities contributing which contradicts the entropy of zero. Am I making a logical mistake/missing something here? Tiago Peixoto wrote
It is difficult to blindly guess, without being given more information.
Once i have verified whether the problem persists with the current git version I will try and provide an MWE. The data is empirical however so I would be surprised by a perfect fit. Best, Philipp -- Sent from: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/
