A Frame is Worth One Token: Efficient Generative World Modeling with Delta Tokens

CVPR 2026

Anticipating diverse future states is a central challenge in video world modeling. Discriminative world models produce deterministic predictions that implicitly average over possible futures, while existing generative world models remain computationally expensive. Recent work demonstrates that predi

Generative Adversarial Reasoner: Enhancing LLM Reasoning with Adversarial Reinforcement Learning

ICLR 2026poster

Large language models (LLMs) with explicit reasoning capabilities excel at mathematical reasoning yet still commit process errors, such as incorrect calculations, brittle logic, and superficially plausible but invalid steps. In this paper, we introduce Generative Adversarial Reasoner, an on-policy j…

Compositional 4D Dynamic Scenes Understanding with Physics Priors for Video Question Answering

ICLR 2025poster

For vision-language models (VLMs), understanding the dynamic properties of objects and their interactions in 3D scenes from videos is crucial for effective reasoning about high-level temporal and action semantics. Although humans are adept at understanding these properties by constructing 3D and tem…

Spatial457: A Diagnostic Benchmark for 6D Spatial Reasoning of Large Mutimodal Models

CVPR 2025highlight

Although large multimodal models (LMMs) have demonstrated remarkable capabilities in visual scene interpretation and reasoning, their capacity for complex and precise 3-dimensional spatial reasoning remains uncertain. Existing benchmarks focus predominantly on 2D spatial understanding and lack a fra…

SpatialLLM: A Compound 3D-Informed Design towards Spatially-Intelligent Large Multimodal Models

CVPR 2025highlight

Humans naturally understand 3D spatial relationships, enabling complex reasoning like predicting collisions of vehicles from different directions. Current large multimodal models (LMMs), however, lack of this capability of 3D spatial reasoning. This limitation stems from the scarcity of 3D training…

Generating Images with 3D Annotations Using Diffusion Models

ICLR 2024spotlight

Diffusion models have emerged as a powerful generative method, capable of producing stunning photo-realistic images from natural language descriptions. However, these models lack explicit control over the 3D structure in the generated images. Consequently, this hinders our ability to obtain detailed…

ImageNet3D: Towards General-Purpose Object-Level 3D Understanding

NeurIPS 2024poster

A vision model with general-purpose object-level 3D understanding should be capable of inferring both 2D (*e.g.*, class name and bounding box) and 3D information (*e.g.*, 3D location and 3D viewpoint) for arbitrary rigid objects in natural images. This is a challenging task, as it involves inferring…

NOVUM: Neural Object Volumes for Robust Object Classification

ECCV 2024poster

"Discriminative models for object classification typically learn image-based representations that do not capture the compositional and 3D nature of objects. In this work, we show that explicitly integrating 3D compositional object representations into deep networks for image classification leads to…

3D-Aware Visual Question Answering about Parts, Poses and Occlusions

NeurIPS 2023poster

Despite rapid progress in Visual question answering (\textit{VQA}), existing datasets and models mainly focus on testing reasoning in 2D. However, it is important that VQA models also understand the 3D structure of visual scenes, for example to support tasks like navigation or manipulation. This i…

Super-CLEVR: A Virtual Benchmark To Diagnose Domain Robustness in Visual Reasoning

CVPR 2023highlight

Visual Question Answering (VQA) models often perform poorly on out-of-distribution data and struggle on domain generalization. Due to the multi-modal nature of this task, multiple factors of variation are intertwined, making generalization difficult to analyze. This motivates us to introduce a virtu…

OOD-CV: A Benchmark for Robustness to Out-of-Distribution Shifts of Individual Nuisances in Natural Images

ECCV 2022poster

"Enhancing the robustness of vision algorithms in real-world scenarios is challenging. One reason is that existing robustness benchmarks are limited, as they either rely on synthetic data or ignore the effects of individual nuisance factors. We introduce ROBIN, a benchmark dataset that includes out-…

Robust Category-Level 6D Pose Estimation with Coarse-to-Fine Rendering of Neural Features

ECCV 2022poster

"We consider the problem of category-level 6D pose estimation from a single RGB image. Our approach represents an object category as a cuboid mesh and learns a generative model of the neural feature activations at each mesh vertex to perform pose estimation through differentiable rendering.
