Penn AI Seminar: Machine Learning for Cosmology

REGISTRATION OPTIONAL!

Professor Jain will describe how we map dark matter from large surveys of galaxies via gravitational lensing. Testing theories of cosmology with maps of galaxies and dark matter is a rich area for machine learning. He will describe the 'old-fashioned' physics-based approaches and the competing deep learning ones. Extracting information from maps on the curved sky also has challenges in common with climate modeling and other fields — Professor Jain will give a few examples.
