For the model comparison, when $\eps[\alpha]$ is small For the model comparison, when $\eps[\alpha]$ is small

On the figure \ref{fig:inference-prop-modele-pref} one can see that from On the figure~\ref{fig:inference-prop-modele-pref} one can see that from

$\pi\rho$-colBiSBM model (i.e., the correct one) is selected. $\pi\rho$-colBiSBM model (i.e., the correct one) is selected.
The figure~\ref{fig:inference-ari-plots} shows that for $\eps[\alpha] \geq 0.09$,
all the models, even the sep, have a
$\overline{\text{ARI}}$ around $0.94$. This indicates that the models are able to
assign correct nodes group memberships and thus that the inference works
correctly.
An interesting result we can read in the tables is that our models outperform An interesting result we can read in the tables is that our models outperform
the $sep\text{-}BiSBM$ when considering the ARI on the whole set of nodes the $sep\text{-}BiSBM$ when considering the ARI on the whole set of nodes
