LocateAnything3D: Vision-Language 3D Detection with Chain-of-Sight

CVPR 2026

To act in the world, a model must name what it sees and know where it is in 3D. Today's vision-language models excel at open-ended 2D description and grounding, yet multi-object 3D detection remains largely missing from the VLM toolbox. We present LocateAnything3D, a VLM-native recipe that casts 3D

DreamGen: Unlocking Generalization in Robot Learning through Video World Models

CoRL 2025poster

In this work, we unlock new capabilities in robot learning from neural trajectories, synthetic robot data generated from video world models. Our proposed recipe is simple, but powerful: we take the most recent state-of-the-art video generative models (world models), adapt them to the target robot em…

FLARE: Robot Learning with Implicit World Modeling

CoRL 2025poster

We introduce **F**uture **LA**tent **R**presentation Alignm**E**nt (**FLARE**), a novel framework that integrates predictive world modeling into robot policy learning. By aligning features from a diffusion transformer with latent embeddings of future observations, **FLARE** enables a diffusion trans…

Image as a Foreign Language: BEiT Pretraining for Vision and Vision-Language Tasks

CVPR 2023poster

A big convergence of language, vision, and multimodal pretraining is emerging. In this work, we introduce a general-purpose multimodal foundation model BEiT-3, which achieves excellent transfer performance on both vision and vision-language tasks. Specifically, we advance the big convergence from th…

Language Is Not All You Need: Aligning Perception with Language Models

NeurIPS 2023poster

A big convergence of language, multimodal perception, action, and world modeling is a key step toward artificial general intelligence. In this work, we introduce KOSMOS-1, a Multimodal Large Language Model (MLLM) that can perceive general modalities, learn in context (i.e., few-shot), and follow ins…

Is High Variance Unavoidable in RL? A Case Study in Continuous Control

ICLR 2022poster

Reinforcement learning (RL) experiments have notoriously high variance, and minor details can have disproportionately large effects on measured outcomes. This is problematic for creating reproducible research and also serves as an obstacle when applying RL to sensitive real-world applications. In th…

Characterizing the Loss Landscape in Non-Negative Matrix Factorization

AAAI 2021technical

Non-negative matrix factorization (NMF) is a highly celebrated algorithm for matrix decomposition that guarantees non-negative factors. The underlying optimization problem is computationally intractable, yet in practice, gradient-descent-based methods often find good solutions. In this paper, we rev…

Towards Deeper Deep Reinforcement Learning with Spectral Normalization

NeurIPS 2021poster

In computer vision and natural language processing, innovations in model architecture that increase model capacity have reliably translated into gains in performance. In stark contrast with this trend, state-of-the-art reinforcement learning (RL) algorithms often use small MLPs, and gains in perform…
