Adaptive Model Pruning and Personalization for Federated Learning over Wireless Networks

no code implementations4 Sep 2023 Xiaonan Liu, Tharmalingam Ratnarajah, Mathini Sellathurai, Yonina C. Eldar

This framework splits the learning model into a global part with model pruning shared with all devices to learn data representations and a personalized part to be fine-tuned for a specific device, which adapts the model size during FL to reduce both computation and communication latency and increases the learning accuracy for devices with non-independent and identically distributed data.

Adaptive Federated Pruning in Hierarchical Wireless Networks

no code implementations15 May 2023 Xiaonan Liu, Shiqiang Wang, Yansha Deng, Arumugam Nallanathan

We present the convergence analysis of an upper on the l2 norm of gradients for HFL with model pruning, analyze the computation and communication latency of the proposed model pruning scheme, and formulate an optimization problem to maximize the convergence rate under a given latency threshold by jointly optimizing the pruning ratio and wireless resource allocation.

Learning-based Prediction and Uplink Retransmission for Wireless Virtual Reality (VR) Network

no code implementations16 Dec 2020 Xiaonan Liu, Xinyu Li, Yansha Deng

While for the online learning algorithm, based on the VR user's actual viewpoint delivered through uplink transmission, we compare it with the predicted viewpoint and update the parameters of the online learning algorithm to further improve the prediction accuracy.
