PAAC: Privacy-Aware Agentic Device-Cloud Collaboration

Liangqi Yuan, Wenzhi Fang, Shiqiang Wang +1

Large language model (LLM) agents face a structural tension: cloud agents provide strong reasoning but expose user data, while on-device agents preserve privacy at the cost of over…

Self-Play Enhancement via Advantage-Weighted Refinement in Online Federated LLM Fine-Tuning with Real-Time Feedback

Seohyun Lee, Wenzhi Fang, Dong-Jun Han +2

Recent works have advanced feedback-based learning systems, whereby a foundation model is able to intake incoming feedback (e.g., a user) to self-improve, creating a self-loop syst…

Joint Continual Learning of Local Language Models and Cloud Offloading Decisions with Budget Constraints

Evan Chen, Wenzhi Fang, Shiqiang Wang +1

Locally deployed Small Language Models (SLMs) must continually support diverse tasks under strict memory and computation constraints, making selective reliance on cloud Large Langu…

Sporadic Gradient Tracking over Directed Graphs: A Theoretical Perspective on Decentralized Federated Learning

Shahryar Zehtabi, Dong-Jun Han, Seyyedali Hosseinalipour +1

Decentralized Federated Learning (DFL) enables clients with local data to collaborate in a peer-to-peer manner to train a generalized model. In this paper, we unify two branches of…

TAP: Two-Stage Adaptive Personalization of Multi-Task and Multi-Modal Foundation Models in Federated Learning

Seohyun Lee, Wenzhi Fang, Dong-Jun Han +2

In federated learning (FL), local personalization of models has received significant attention, yet personalized fine-tuning of foundation models remains underexplored. In particul…

Bridging On-Device and Cloud LLMs for Collaborative Reasoning: A Unified Methodology for Local Routing and Post-Training

Wenzhi Fang, Dong-Jun Han, Liangqi Yuan +2

Device-cloud collaboration holds promise for deploying large language models (LLMs), leveraging lightweight on-device models for efficiency while relying on powerful cloud models f…
