Spatio-Temporal LLM: Reasoning about Environments and Actions

ICML 2026poster

Despite significant recent progress of Multimodal Large Language Models (MLLMs), current MLLMs are challenged by "spatio-temporal" prompts, i.e., prompts that refer to 1) the entirety of an environment encoded in a point cloud that the MLLM should consider; and simultaneously also refer to 2) action…

MV-DUSt3R+: Single-Stage Scene Reconstruction from Sparse Views In 2 Seconds

CVPR 2025poster

Recent sparse multi-view scene reconstruction advances like DUSt3R and MASt3R no longer require camera calibration and camera pose estimation. However, they only process a pair of views at a time to infer pixel-aligned pointmaps. When dealing with more than two views, a combinatorial number of error…

NeRFDeformer: NeRF Transformation from a Single View via 3D Scene Flows

CVPR 2024poster

We present a method for automatically modifying a NeRF representation based on a single observation of a non-rigid transformed version of the original scene. Our method defines the transformation as a 3D flowspecifically as a weighted linear blending of rigid transformations of 3D anchor points that…

RGB-Only Reconstruction of Tabletop Scenes for Collision-Free Manipulator Control

ICRA 2023poster

We present a system for collision-free control of a robot manipulator that uses only RGB views of the world. Perceptual input of a tabletop scene is provided by multiple images of an RGB camera (without depth) that is either handheld or mounted on the robot end effector. A NeRF-like process is used…

Discovering Diverse Multi-Agent Strategic Behavior via Reward Randomization

ICLR 2021poster

We propose a simple, general and effective technique, Reward Randomization for discovering diverse strategic policies in complex multi-agent games. Combining reward randomization and policy gradient, we derive a new algorithm, Reward-Randomized Policy Gradient (RPG). RPG is able to discover a set of…
