CARFF: Conditional Auto-encoded Radiance Field for 3D Scene Forecasting

no code implementations31 Jan 2024 Jiezhi Yang, Khushi Desai, Charles Packer, Harshil Bhatia, Nicholas Rhinehart, Rowan Mcallister, Joseph Gonzalez

We demonstrate the utility of our method in realistic scenarios using the CARLA driving simulator, where CARFF can be used to enable efficient trajectory and contingency planning in complex multi-agent autonomous driving scenarios involving visual occlusions.

Hindsight Task Relabelling: Experience Replay for Sparse Reward Meta-RL

no code implementations NeurIPS 2021 Charles Packer, Pieter Abbeel, Joseph E. Gonzalez

Meta-reinforcement learning (meta-RL) has proven to be a successful framework for leveraging experience from prior tasks to rapidly learn new related tasks, however, current meta-RL approaches struggle to learn in sparse reward environments.
