On the Importance of Hyperparameter Optimization for Model-based Reinforcement Learning

We showed that advancements in AutoML when paired with common deep RL tasks, MBRL algorithms perform so well they break the simulator.

AI Development for the Public Interest: From Abstraction Traps to Sociotechnical Risks

Learn more.
We study three developing subfields of AI research and their growing relationship with the sociotechnical: AI Safety, Fair Machine Learning, and Human-in-the-loop Autonomy.
