[graph-tool] Problem on bipartite-networks with label

2021-06-27 Thread filippo . valle
I am using [SBMtopicmodeling](https://github.com/martingerlach/hSBM_Topicmodel) 
to inference partition on bipartite networks

After a recent graph-tool update I noticed there is a problem with 
**state_args** in minimize_nested_blockmodel_dl

step to reproduce:
given a trivial bi-partite network, with VertexProperty **kind** that imposes 
the bi-partition

clabel = g.vp['kind']
state_args = {}
state = gt.minimize_nested_blockmodel_dl(g, state_args=state_args)

finds partitions

but when I impose bi-partition

clabel = model.g.vp['kind']
state_args = {'clabel': clabel, 'pclabel': clabel}
state = gt.minimize_nested_blockmodel_dl(g, state_args=state_args)

it fails to find any partition.

What could be the problem?

[graph-tool] Question about entropy

2021-04-16 Thread Filippo Valle
Hello,

I am running minimize_nested_blockmodel_dl on a certain network and obtaining 
some partition, good.

Then I add some nodes to the network and I do another run of 
minimize_nested_blockmodel_dl and obtain another partition.

The question I want to answer is: does adding those nodes help me finding a 
better partition?

I am going to compare NestedBlockState.entropy() of the two run, but I am not 
sure this is correct.
How should I take into account the fact that the networks are slightly 
different?

Thank you in advance for any help

Best Regards,

Filippo Valle
