DESCRIPTION:Speakers: Torsten Enßlin (MPI for Astrophysics)\n\nFields pla
 y a central role in all areas of astrophysics\, like the density\, velocit
 y\, magnetic\, or gravitational field. Inferring an astrophysical field fr
 om data is an ill posed problem\, as the finite\, noisy\, and incomplete d
 ata can not alone constrain the infinite number of degrees of freedom of a
  function over continuous space. Domain knowledge has to regularize the se
 t of possible solutions\, however\, usually significant uncertainties rema
 in and need to be quantified. This can be done via information field theor
 y (IFT)\, which is a mathematical formulation of probabilistic field infer
 ence. Here\, the basic concepts of IFT and its numerical implementation ar
 e introduced. Its application to astrophysical datasets is shown large for
  the ongoing project to build an atlas of the Milky Way.\n\nhttps://indico
