Active Movable-Element RIS Assisted Vehicular Semantic Communications: Modeling and Optimization
Maoxin Ji, Qiong Wu, Jingbo Zhang +5
The paper proposes a vehicular semantic communication system that employs a row‑movable active reconfigurable intelligent surface (RM‑A‑RIS) whose elements can both move and amplif…
Federated Client Selection under Partial Visibility: A POMDP Approach with Spatio-Temporal Attention
Qijun Hou, Yuchen Shi, Pingyi Fan +1
Federated learning relies on effective client selection to alleviate the performance degradation caused by data heterogeneity. Most existing methods assume full visibility of all c…
SpaceMoE: Realizing Distributed Mixture-of-Experts Inference over Space Networks
Zhanwei Wang, Huiling Yang, Min Sheng +2
Leveraging continuous solar energy harvesting at high efficiency, space data centers are envisioned as a promising platform for executing energy-intensive large language models (LL…
PCDM: A Diffusion-Based Data Poisoning Attack Against Federated Learning Systems
Wei Sun, Yijun Chen, Bo Gao +4
Federated learning (FL) is vulnerable to data poisoning attacks due to its distributed nature. Although recent GAN-based data poisoning methods have indicated the potential of usin…
FedGMI: Generative Model-Driven Federated Learning for Probabilistic Mixture Inference
Qijun Hou, Yuchen Shi, Pingyi Fan +1
Federated Learning (FL) facilitates collaborative model training across decentralized clients while preserving data privacy by avoiding raw data exchange. Despite its potential, FL…
Generative AI Meets 6G and Beyond: Diffusion Models for Semantic Communications
Hai-Long Qin, Jincheng Dai, Guo Lu +6
Semantic communications mark a paradigm shift from bit-accurate transmission toward meaning-centric communication, essential as wireless systems approach theoretical capacity limit…
