Machine Learning Enhances Weak-Lensing Cosmology
The Gist
Machine learning is improving the extraction of cosmological information from weak gravitational lensing data.
Explain Like I'm Five
"Imagine the universe is a giant lens. Machine learning helps us see the invisible stuff (dark matter) by how it bends light."
