Cosmology in the machine learning era
Event Start:

Event End:

Event Information:
Recent advances in deep learning are triggering a revolution across fields in science. In this talk I will show how these techniques can also benefit cosmology and astrophysics. I will present a new approach whose final goal is to extract every single bit of information from cosmological surveys. I will start showing the large amount of cosmological information that is embedded on small, non-linear, scales; information that cannot be retrieved using the traditional power spectrum. I will then show how neural networks can learn the optimal estimator needed to extract that information.
