Deep Learning at scale for the construction of galaxy catalogs - insideHPC

A team of scientists is now applying the power of artificial intelligence (AI) and high-performance supercomputers to accelerate efforts to analyze the increasingly massive datasets produced by ongoing and future cosmological surveys. In a new study, researchers from NCSA and Argonne have developed a novel combination of deep learning methods to provide a highly accurate approach to classifying hundreds of millions of unlabeled galaxies. The team's findings were published in Physics Letters B. "The NCSA Gravity Group initiated, and continues to spearhead, the use of deep learning at scale for gravitational wave astrophysics. We have expanded our research portfolio to address a computational grand challenge in cosmology, innovating the use of several deep learning methods in combination with high-performance computing (HPC)," said Eliu Huerta, NCSA Gravity Group Lead. "Our work also showcases how the interoperability of NSF and DOE supercomputing resources can be used to accelerate science."
