Hi Tiago,

For the non-parametric weighted SBMs, how can I extract the "description length" from the the state.entropy() method? Is it also equivalent of having the maximum entropy values after running the algorithm multiple times ?

I also have a theoretical question: I read most of your recent papers and I see this statement but I could not find more description why it is the case?

Why do you use the "micro-canonical formulation"? You stated that "it approaches to the canonical distributions asymptotically". In case you have explained it in one of your papers, would you kindly refer me to the right paper?

Thanks in advance.

Best,

Zahra

You should run the algorithm multiple times, and choose the result with the
smallest description length. You get this value via the method state.entropy().

Best,
Tiago
