Collaborative Reinforcement Learning Based Unmanned Aerial Vehicle (UAV) Trajectory Design for 3D UAV Tracking

no code implementations22 Jan 2024 Yujiao Zhu, Mingzhe Chen, Sihua Wang, Ye Hu, Yuchen Liu, Changchuan Yin

Meanwhile, since the accuracy of the distance estimation depends on the signal-to-noise ratio of the transmission signals, the active UAV must optimize its transmit power.

Digital Over-the-Air Federated Learning in Multi-Antenna Systems

no code implementations4 Feb 2023 Sihua Wang, Mingzhe Chen, Cong Shen, Changchuan Yin, Christopher G. Brinton

The PS, acting as a central controller, generates a global FL model using the received local FL models and broadcasts it back to all devices.

Performance Optimization for Variable Bitwidth Federated Learning in Wireless Networks

no code implementations21 Sep 2022 Sihua Wang, Mingzhe Chen, Christopher G. Brinton, Changchuan Yin, Walid Saad, Shuguang Cui

Compared to model-free RL, this model-based RL approach leverages the derived mathematical characterization of the FL training process to discover an effective device selection and quantization scheme without imposing additional device communication overhead.

A Machine Learning Approach for Task and Resource Allocation in Mobile Edge Computing Based Networks

no code implementations20 Jul 2020 Sihua Wang, Mingzhe Chen, Xuanlin Liu, Changchuan Yin, Shuguang Cui, H. Vincent Poor

Since the data size of each computational task is different, as the requested computational task varies, the BSs must adjust their resource (subcarrier and transmit power) and task allocation schemes to effectively serve the users.

Federated Learning for Task and Resource Allocation in Wireless High Altitude Balloon Networks

no code implementations19 Mar 2020 Sihua Wang, Mingzhe Chen, Changchuan Yin, Walid Saad, Choong Seon Hong, Shuguang Cui, H. Vincent Poor

This problem is posed as an optimization problem whose goal is to minimize the energy and time consumption for task computing and transmission by adjusting the user association, service sequence, and task allocation scheme.
