We are pleased to announce a workshop on *Bayesian Deep Learning for Cosmology and Gravitational waves* which
will be held on March 4-6 2020 at Laboratoire AstroParticule et Cosmologie, Université de Paris, France.

Machine learning attracts a lot of interest in the fields of cosmology and gravitational-wave astronomy and may
potentially lead to major breakthroughs. Its adoption by the scientific community is increasing dramatically but it
does not yet belong to the toolbox of 'off-the-shelf' algorithms. One of the reasons is that built-in uncertainty
estimation, which is core to the evaluation of any scientific measurement and analysis, is not yet common
in machine learning models.

Such limitation is on the verge to be overcome by the emergence of probabilistic machine learning models and
algorithms. Among them, recent models called Bayesian neural networks, which combine machine learning and
Bayesian statistics, use new (deep) neural networks architectures to enable Bayesian inference, and have received
a great attention from the artificial intelligence community over the past few years.

This workshop will give the participants the opportunity to learn more about these emerging methods and how to
use and exploit them in their research. The workshop program includes invited lectures and tutorials from major
computer science experts and contributed talk and poster sessions aimed at sharing experience between physicists
on the practical applications of machine learning.

Registrations are opened.

The deadline for submitting abstracts is *Feb 2nd 2020*.

This workshop is part of the Paris Centre for Cosmological Physics Workshop Series.
