Temporal-Distance JEPA: Plan-Aware Representation Learning for Latent World Model Predictive Control
Jiaxin Bai, Jiaxuan Xiong
The paper introduces Temporal-Distance JEPA, a method that learns a directed temporal cost from offline trajectories to improve latent world model predictive control, enhancing pla…
VisualPatchWorld: Code World Models as Latent Structured Representations for Planning
Jiaxin Bai, Jiaxuan Xiong
The paper presents VisualPatchWorld, a system that learns compact code programs to model world dynamics from visual observations, enabling inspection, simulation, and use in model-…
PatchWorld: Gradient-Free Optimization of Executable World Models for Agent Environments
Jiaxin Bai, Yue Guo, Yifei Dong +13
World models for interactive text agents must typically be learned from observation-action trajectories alone. Specifically, the environment returns text observations after each ac…
NGDBench: Towards Neural Graph Data Management
Yufei Li, Yisen Gao, Jiaxuan Xiong +6
Data critical to real-world decision-making is increasingly found within organizations. Such data is heterogeneous, constantly evolving, and only imperfectly captured. However, cur…
