Fast cosmic web simulations with generative adversarial networks

no code implementations27 Jan 2018 Andres C. Rodriguez, Tomasz Kacprzak, Aurelien Lucchi, Adam Amara, Raphael Sgier, Janis Fluri, Thomas Hofmann, Alexandre Réfrégier

Computational models of the underlying physical processes, such as classical N-body simulations, are extremely resource intensive, as they track the action of gravity in an expanding universe using billions of particles as tracers of the cosmic matter distribution.

Cosmological model discrimination with Deep Learning

no code implementations17 Jul 2017 Jorit Schmelzle, Aurelien Lucchi, Tomasz Kacprzak, Adam Amara, Raphael Sgier, Alexandre Réfrégier, Thomas Hofmann

We find that our implementation of DCNN outperforms the skewness and kurtosis statistics, especially for high noise levels.
