Shaping the Wind: Nested Potentials for Kinematically Admissible Urban Wind Prediction

Yidi Wang, Yunhe Zhang, Jiawei Gu وآخرون · 2026

Predicting transient urban winds is fundamental to understanding urban microclimates and designing climate-resilient cities. Building-resolving large-eddy simulation produces detailed incompressible urban wind fields at substantial computational cost for each layout. Neural surrogates offer a faster alternative by lear …

Relative Transitions, Not Absolute Destinations: A Transfer-and-Ground Framework for Target-Trajectory-Free Human Mobility Generation

Yidi Wang, Yunhe Zhang, Bangchao Deng وآخرون · 2026

Individual mobility trajectories support urban analysis and location-based services, yet most trajectory generators require observations from their deployment city. This assumption excludes precisely the cities where trajectories are unavailable even though points of interest (POIs) and their attributes can be obtained …

Is This Evidence Decision-Critical? Learning to Verify Rule-Governed Decisions

Haoyang Zhang, Jianpeng Zhao, Qi Hao وآخرون · 2026

Rule-based reasoning, as in eligibility checks and contract reviews, requires language models to assess evidence against individual conditions and combine their judgments under explicit rules. Errors in evidence assessment can leave a decision unchanged, but misinterpreting or overlooking decision-critical evidence can …

RGDT-Bench: Benchmarking LLM Reasoning for Rule-Governed Decisions and Their Justifications

Jianpeng Zhao, Haihua Xu, Haoyang Zhang وآخرون · 2026

We study reasoning in Rule-Governed Decision Tasks (RGDTs), where models apply external rules to case facts and justify decisions, as required in policy, contract, and compliance settings. Beyond the deductive capability emphasized by standard mathematical and logical reasoning tasks, RGDTs require interpreting rules a …
