A revised lower estimate of ozone columns during Earth's oxygenated history

no code implementations23 Feb 2021 Gregory Cooke, Dan Marsh, Catherine Walsh, Benjamin Black, Jean-François Lamarque

Using a three-dimensional chemistry-climate model, we simulate changes in O$_3$ in Earth's atmosphere since the GOE and consider the implications for surface habitability, and glaciation during the Mesoproterozoic.

Revisiting Parameter Sharing in Multi-Agent Deep Reinforcement Learning

2 code implementations27 May 2020 J. K. Terry, Nathaniel Grammel, Sanghyun Son, Benjamin Black, Aakriti Agrawal

Next, we formally introduce methods to extend parameter sharing to learning in heterogeneous observation and action spaces, and prove that these methods allow for convergence to optimal policies.
