Recursive Flow Matching
Jiahe Huang, Sihan Xu, Sharvaree Vadgama +1
Generative models have emerged as a powerful paradigm for solving physics systems and modeling complex spatiotemporal dynamics. However, achieving high physical accuracy without in…
Generative OOD-regularized Model-based Policy Optimization
Aysin Tumay, Jiahe Huang, Elise Jortberg +1
We study sequential decision-making with offline reinforcement learning (RL). Traditional offline RL policies may result in out-of-distribution (OOD) actions when training relies o…
SimulCost: A Cost-Aware Benchmark and Toolkit for Automating Physics Simulations with LLMs
Yadi Cao, Sicheng Lai, Jiahe Huang +12
Evaluating LLM agents for scientific tasks has focused on token costs while ignoring tool-use costs like simulation time and experimental resources. As a result, metrics like pass@…
VideoPDE: Unified Generative PDE Solving via Video Inpainting Diffusion Models
Edward Li, Zichen Wang, Jiahe Huang +1
We present a unified framework for solving partial differential equations (PDEs) using video-inpainting diffusion transformer models. Unlike existing methods that devise specialize…
DiffusionPDE: Generative PDE-Solving Under Partial Observation
Jiahe Huang, Guandao Yang, Zichen Wang +1
We introduce a general framework for solving partial differential equations (PDEs) using generative diffusion models. In particular, we focus on the scenarios where we do not have…
SpaceMeta: Global-Scale Massive Multi-User Virtual Interaction over LEO Satellite Constellations
Jiahe Huang, Yifei Zhu
Low latency and high synchronization among users are critical for emerging multi-user virtual interaction applications. However, the existing ground-based cloud solutions are natur…
