Detecting hyperbolic geometry in networks: why triangles are not enough
Riccardo Michielan, Nelly Litvak, Clara Stegehuis
In the past decade, geometric network models have received vast attention in the literature. These models formalize the natural idea that similar vertices are likely to connect. Be…
The role of inter-regional mobility in forecasting SARS-CoV-2 transmission
Martijn H. H. Schoot Uiterkamp, Martijn Gösgens, Hans Heesterbeek +2
In this paper, we present a method to forecast the spread of SARS-CoV-2 across regions with a focus on the role of mobility. Mobility has previously been shown to play a significan…
The Hyperspherical Geometry of Community Detection: Modularity as a Distance
Martijn Gösgens, Remco van der Hofstad, Nelly Litvak
We introduce a metric space of clusterings, where clusterings are described by a binary vector indexed by the vertex-pairs. We extend this geometry to a hypersphere and prove that…
Locating highly connected clusters in large networks with HyperLogLog counters
Lotte Weedage, Nelly Litvak, Clara Stegehuis
In this paper we introduce a new method to locate highly connected clusters in a network. Our proposed approach adapts the HyperBall algorithm to localize regions with a high densi…
Containment strategies after the first wave of COVID-19 using mobility data
Martijn Gösgens, Teun Hendriks, Marko Boon +5
In their response to the COVID-19 outbreak, governments face the dilemma to balance public health and economy. Mobility plays a central role in this dilemma because the movement of…
Red Light Green Light Method for Solving Large Markov Chains
Konstantin Avrachenkov, Patrick Brown, Nelly Litvak
Discrete-time discrete-state finite Markov chains are versatile mathematical models for a wide range of real-life stochastic processes. One of most common tasks in studies of Marko…
