Communication protocol for a satellite-swarm interferometer

no code implementations25 Dec 2023 Oliver Nagy, Manish Pandey, Georgios Exarchakos, Mark Bentum, Remco van der Hofstad

Orbiting low frequency antennas for radio astronomy (OLFAR) that capture cosmic signals in the frequency range below 30MHz could provide valuable insights on our Universe.

On a Near-Optimal \& Efficient Algorithm for the Sparse Pooled Data Problem

no code implementations22 Dec 2023 Max Hahn-Klimroth, Remco van der Hofstad, Noela Müller, Connor Riddlesden

In this article, we resolve the question whether this $\log n$-gap is artificial or of a fundamental nature by the design of an efficient algorithm, called \algoname, based upon a novel pooling scheme on a number of pools very close to the information-theoretic threshold.

The Hyperspherical Geometry of Community Detection: Modularity as a Distance

1 code implementation6 Jul 2021 Martijn Gösgens, Remco van der Hofstad, Nelly Litvak

In that sense, modularity-based community detection methods can be seen as a subclass of a more general class of projection methods, which we define as the community detection methods that adhere to the following two-step procedure: first, mapping the network to a point on the hypersphere; second, projecting this point to the set of clustering vectors.
