Probabilistic Autoencoder Using Fisher Information

Autor: Johannes Zacherl, Philipp Frank, Torsten A. Enßlin

Publikováno v: Entropy, Vol 23, Iss 12, p 1640 (2021)

Neural networks play a growing role in many scientific disciplines, including physics. Variational autoencoders (VAEs) are neural networks that are able to represent the essential information of a high dimensional data set in a low dimensional latent

Geometric Variational Inference

Autor: Philipp Frank, Reimar Leike, Torsten A. Enßlin

Publikováno v: Entropy, Vol 23, Iss 7, p 853 (2021)

Efficiently accessing the information contained in non-linear and high dimensional probability distributions remains a core challenge in modern statistics. Traditionally, estimators that go beyond point estimates are either categorized as Variational

Bayesian Reasoning with Trained Neural Networks

Autor: Jakob Knollmüller, Torsten A. Enßlin

Publikováno v: Entropy, Vol 23, Iss 6, p 693 (2021)

We showed how to use trained neural networks to perform Bayesian reasoning in order to solve tasks outside their initial scope. Deep generative models provide prior knowledge, and classification/regression networks impose constraints. The tasks at ha

Optimal Belief Approximation

Autor: Reimar H. Leike, Torsten A. Enßlin

Publikováno v: Entropy, Vol 19, Iss 8, p 402 (2017)

In Bayesian statistics probability distributions express beliefs. However, for many problems the beliefs cannot be computed analytically and approximations of beliefs are needed. We seek a loss function that quantifies how “embarrassing” it is to

Puzzling large-scale polarization in the galaxy cluster Abell 523

Autor: Valentina Vacca, Federica Govoni, Matteo Murgia, Richard A Perley, Luigina Feretti, Gabriele Giovannini, Ettore Carretti, Fabio Gastaldello, Filippo Cova, Paolo Marchegiani, Elia Battistelli, Walter Boschin, Torsten A Enßlin, Marisa Girardi, Francesca Loi, Federico Radiconi

Large-scale magnetic fields reveal themselves through diffuse synchrotron sources observed in galaxy clusters such as radio halos. Total intensity filaments of these sources have been observed in polarization as well, but only in three radio halos ou

Astronomy & Astrophysics, 657, pp. 1-14

This work gives an update to existing reconstructions of the Galactic Faraday rotation sky by processing almost all Faraday rotation data sets available at the end of the year 2020. Observations of extra-Galactic sources in recent years have, among o

The Per-Tau Shell: A Giant Star-Forming Spherical Shell Revealed by 3D Dust Observations

Autor: Robert A. Benjamin, Catherine Zucker, Shmuel Bialy, Alyssa A. Goodman, Torsten A. Enßlin, João Alves, Vadim A. Semenov, Michael M. Foley, Reimar Leike

A major question in the field of star formation is how molecular clouds form out of the diffuse Interstellar Medium (ISM). Recent advances in 3D dust mapping are revolutionizing our view of the structure of the ISM. Using the highest-resolution 3D du

Diffuse radio emission at the centre of galaxy clusters has been observed both in merging clusters on scales of Mpc, called giant radio haloes, and in relaxed systems with a cool-core on smaller scales, named mini haloes. Giant radio haloes and mini
