Perraudin, Nathanaël, Defferrard, Michaël, Kacprzak, Tomasz et al.

Understand

Convolutional Neural Networks (CNNs) are a cornerstone of the Deep Learning toolbox and have led to many breakthroughs in Artificial Intelligence.

  • These networks have mostly been developed for regular Euclidean domains such as those supporting images, audio, or video.
  • Because of their success, CNN-based methods are becoming increasingly popular in Cosmology.
  • Cosmological data often comes as spherical maps, which make the use of the traditional CNNs more complicated.
