At the same time, this technology makes it possible to optimize the materials used. Depending on the type of product, and assuming an efficiency of 85%, XL 9.1/9.2 block machines can produce up to 3,000 m² of pavers or up to 30,000 hollow blocks (400 x 200 x 200 mm) per shift (8 hours).
This work introduces multilayer stochastic block models (SBMs), a generalization of single-layer SBMs that considers different mechanisms of layer aggregation, and finds the complete probabilistic solution to the problem of finding the optimal multilayers SBM for a given aggregate observed network. In complex systems, …

Multilayer networks are a useful data structure for simultaneously capturing multiple types of relationships between a set of nodes. In such networks, each relational definition gives rise to a layer. While each layer provides its own set of information, community structure across layers can be collectively utilized to discover and quantify …
Significant progress has been made recently on theoretical analysis of estimators for the stochastic block model (SBM). In this paper, we consider the multi-graph SBM, which …
In particular, extensions of the SBM for sets of networks include repeated measurements of a ground-truth SBM network (Le et al., 2018), a mixture of SBMs with fixed nodes (Stanley et al., 2016 ...

Simulation of mixture multilayer Stochastick block model Description. This simulation process assumes that we have partial information on the clustering within each view component, and that the final clustering of individuals depends on a combination of the clustering on each of the views.
That is, layers in a stratum exhibit similar node-to-community assignments and SBM probability parameters. Fitting the sMLSBM to a multilayer network provides a joint clustering that yields node-to-community and layer-to-stratum assignments, which cooperatively aid one another during inference. We describe an algorithm for separating …

In this work, we propose an original method for aggregating multiple clustering coming from different sources of information. Each partition is encoded by a co-membership matrix between observations. Our approach uses a mixture of multilayer Stochastic Block Models (SBM) to group co-membership matrices with similar information into …
To demonstrate a situation where the sMLSBM framework has a clear advantage over other models, we designed a synthetic experiment and compared the results to two different SBM approaches: i) fitting a single SBM to all of the layers (denoted "single SBM"), and ii). fitting a stochastic block model to each layer individually (denoted ...
Our approach uses a mixture of multilayer stochastic block models to group co-membership matrices with similar information into components and to partition observations into different clusters. See De Santiago (2023, ISBN: 978-2-87587-088-9).
SBM literature and has been extensively studied in prior works [10], [14]–[17], [20], [23], [24]. In future work, it is worthwhile extending our investigation ... complementary models for multi-layer SBMs [28]–[32]. Based on the underlying community structure, a collection of graphs are generated on the same set of nodes with identical latent
work with multilayer SBMs. We start by noting that any multilayer SBM can be represented as a single-layer SBM [Fig. 2(a)] [46]. In the single-layer SBM, each group comprises the nodes that belong to the same pair of groups α, γ in P1 and β, δ in P2 in the multilayer SBM (and only those); we call the single-layer partition the intersection ...

communities in multilayer networks, we consider the stochastic block model (SBM) [22], a popular generative model for community structure in networks. The assumption of the SBM is that nodes in a particular community are related to nodes within and between communities in the same way, thus allowing SBMs to describe several types of …
