“…In ecology, bipartite and multipartite networks are common and the model extension (Govaert and Nadif, 2003;Bar-Hen et al, 2020) is straightforward (although some additional modeling choices arise when considering π-colSBM , δ-colSBM or δπ-colSBM ), the main difficulty would then lie in the algorithmic part. Additionally, incorporating the type of ecological interaction as a network covariate (Mariadassou et al, 2010) would help us understand its impact on the structure of the networks and to the robustness of the ecosystems they depict (Chabert-Liddell et al, 2022). The main idea of this article could also be extended to the Degree Corrected SBM (Karrer and Newman, 2011) which is quite used in practice.…”
