TraceFix: Repairing Agent Coordination Protocols with TLA+ Counterexamples
Shuren Xia, Qiwei Li, Taqiya Ehsan +1
We present TraceFix, a verification-first pipeline for Large Language Model (LLM) multi-agent coordination. An agent synthesizes a protocol topology as a structured intermediate re…
CityOS: Privacy Architecture for Urban Sensing
Giorgio Cavicchioli, Mark Chen, Navid Salami Pargoo +5
Cities are rapidly deploying sensing infrastructure -- cameras, environmental sensors, and connected kiosks -- that continuously observe public spaces, yet they lack a system archi…
GRID: Graph-based Reasoning for Intervention and Discovery in Built Environments
Taqiya Ehsan, Shuren Xia, Jorge Ortiz
Manual HVAC fault diagnosis in commercial buildings takes 8-12 hours per incident and achieves only 60 percent diagnostic accuracy, reflecting analytics that stop at correlation in…
The Streetscape Application Services Stack (SASS): Towards a Distributed Sensing Architecture for Urban Applications
Navid Salami Pargoo, Mahshid Ghasemi, Shuren Xia +8
As urban populations grow, cities are becoming more complex, driving the deployment of interconnected sensing systems to realize the vision of smart cities. These systems aim to im…
