Adaptive Matching for Expert Systems with Uncertain Task Types
Virag Shah, Lennart Gulikers, Laurent Massoulie +1
A matching in a two-sided market often incurs an externality: a matched resource may become unavailable to the other side of the market, at least for a while. This is especially an…
Non-Backtracking Spectrum of Degree-Corrected Stochastic Block Models
Lennart Gulikers, Marc Lelarge, Laurent Massoulié
Motivated by community detection, we characterise the spectrum of the non-backtracking matrix in the Degree-Corrected Stochastic Block Model. Specifically, we consider a random…
An Impossibility Result for Reconstruction in a Degree-Corrected Planted-Partition Model
Lennart Gulikers, Marc Lelarge, Laurent Massoulié
We consider the Degree-Corrected Stochastic Block Model (DC-SBM): a random graph on nodes, having i.i.d. weights (possibly heavy-tailed), partitioned into $q \g…
Explosiveness of Age-Dependent Branching Processes with Contagious and Incubation Periods
Lennart Gulikers
We study explosiveness of age-dependent branching processes describing the early stages of an epidemic-spread: both forward- and backward process are analysed. For the classical ag…
A spectral method for community detection in moderately-sparse degree-corrected stochastic block models
Lennart Gulikers, Marc Lelarge, Laurent Massoulié
We consider community detection in Degree-Corrected Stochastic Block Models (DC-SBM). We propose a spectral clustering algorithm based on a suitably normalized adjacency matrix. We…
The effect of perception anisotropy on particle systems describing pedestrian flows in corridors
Lennart Gulikers, Joep Evers, Adrian Muntean +1
We consider a microscopic model (a system of self-propelled particles) to study the behaviour of a large group of pedestrians walking in a corridor. Our point of interest is the ef…
