Optimizing machine learning methods to discover strong gravitational lenses in the Deep Lens Survey

Keerthi Vasan G. C., Stephen Sheng, Tucker Jones +2

Machine learning models can greatly improve the search for strong gravitational lenses in imaging surveys by reducing the amount of human inspection required. In this work, we test…
