Distributionally Robust Wireless Semantic Communication with Large AI Models
Distributionally robust semantic transmission for large-model inference across noisy, bandwidth-limited, and shifting wireless environments.
Contributed modelling, experiment design, robust training simulations, and evaluation under constrained channels.
SubmittedFeDEQ · 2025-present
Federated Deep Equilibrium Learning over Resource-Constrained Edge Networks
Federated deep equilibrium models for heterogeneous clients where memory, energy, data, and communication capacity vary across the network.
Implemented FeDEQ components, explored communication-efficient aggregation, and evaluated non-IID NLP and vision settings.
