A network community detection method with integration of data from multiple layers and node attributes

no code implementations22 May 2023 Hannu Reittu, Lasse Leskelä, Tomi Räty

The number of columns is allowed to be arbitrary, so that the data matrix can be easily expanded by adding columns.

Multilayer hypergraph clustering using the aggregate similarity matrix

no code implementations27 Jan 2023 Kalle Alaluusua, Konstantin Avrachenkov, B. R. Vinay Kumar, Lasse Leskelä

We consider the community recovery problem on a multilayer variant of the hypergraph stochastic block model (HSBM).

Adaptive and optimized COVID-19 vaccination strategies across geographical regions and age groups

1 code implementation24 May 2021 Jeta Molla, Alejandro Ponce de León Chávez, Takayuki Hiraoka, Tapio Ala-Nissila, Mikko Kivelä, Lasse Leskelä

We evaluate the efficiency of various heuristic strategies for allocating vaccines against COVID-19 and compare them to strategies found using optimal control theory.

Community recovery in non-binary and temporal stochastic block models

1 code implementation11 Aug 2020 Konstantin Avrachenkov, Maximilien Dreveton, Lasse Leskelä

This article studies the estimation of latent community memberships from pairwise interactions in a network of $N$ nodes, where the observed interactions can be of arbitrary type, including binary, categorical, and vector-valued, and not excluding even more general objects such as time series or spatial point patterns.

Towards analyzing large graphs with quantum annealing and quantum gate computers

no code implementations30 Jun 2020 Hannu Reittu, Ville Kotovirta, Lasse Leskelä, Hannu Rummukainen, Tomi Räty

The use of quantum computing in graph community detection and regularity checking related to Szemeredi's Regularity Lemma (SRL) are demonstrated with D-Wave Systems' quantum annealer and simulations.
