Sequential decision-making

Learn representations that improve action. We study representation learning, model-based planning, and reward construction for agents that must learn from pixels, sparse feedback, and changing environments.

Research question

What should an agent remember, predict, and explore in order to act well over time?

We study representation learning, model-based planning, and reward construction for agents that must learn from pixels, sparse feedback, and changing environments.

  • Visual reinforcement learning
  • Model-based planning
  • Object-centric rewards
  • Representation learning
