Hit-and-Run Mixes as Fast as the Ball Walk
Ruizhe Zhang
Let be an isotropic convex body. We prove that the hit-and-run walk, started from any -warm distribution, reaches total-variation distance f…
AlayaWorld: Interactive Long-Horizon World Modeling -- Full Technical Report
AlayaWorld Team, Kaipeng Zhang, Chuanhao Li +15
Unlike conventional video game development, which relies on labor-intensive pipelines for asset production, animation, physics, and programming, video world models generate interac…
AlayaWorld: Long-Horizon and Playable Video World Generation
AlayaWorld Team, Kaipeng Zhang, Chuanhao Li +14
Game worlds have traditionally been built through labor-intensive production pipelines, making them costly to develop, difficult to customization, and expensive to modify after dep…
WorldMark: A Unified Benchmark Suite for Interactive Video World Models
Xiaojie Xu, Zhengyuan Lin, Kang He +5
Unlike text- or image-driven video generation, an interactive world model is driven by actions: the user acts, and the world responds. Two obstacles stand in the way of fair and co…
Self-Evaluation Unlocks Any-Step Text-to-Image Generation
Xin Yu, Xiaojuan Qi, Zhengqi Li +6
We introduce the Self-Evaluating Model (Self-E), a novel, from-scratch training approach for text-to-image generation that supports any-step inference. Self-E learns from data simi…
Removing Distributional Discrepancies in Captions Improves Image-Text Alignment
Yuheng Li, Haotian Liu, Mu Cai +5
In this paper, we introduce a model designed to improve the prediction of image-text alignment, targeting the challenge of compositional understanding in current visual-language mo…
