Federated learning (FL) attracts widespread attention due to its powerful resource aggregation capabilities and advantages in privacy protection. However, during the model training process, restricted by limited communication resources and poor channel conditions, it is challenging to achieve a large number of devices access while ensuring signal strength, which becomes a bottleneck affecting the ...Show More
The rapid response and high energy efficiency of the unmanned aerial vehicle (UAV) are crucial prerequisites for enabling time-sensitive and long-endurance target tracking missions, such as search and rescue, area reconnaissance, and convoy monitoring. However, existing research in target tracking primarily focuses on enhancing tracking accuracy, which struggles to adapt to tasks considering stric...Show More
Federated learning (FL), utilizing data from the edge devices (EDs) while protecting user privacy has gained much attention. Its efficacy is substantially influenced by both the quantity of connected devices and the quality of wireless communications. Network congestion, resulting from multiple access and signal attenuation caused by physical obstacles may severely impact the convergence of the FL...Show More
With the rapid development of wireless communication networks, UAVs serving as base stations are increasingly being applied in various scenarios which not only include edge computation and task offloading, but also involve emergency communication, vehicular network enhancement, etc. In order to enhance the utility of UAV base stations’ allocation and deployment, a series of algorithms have been pr...Show More
This paper studies a distributed machine learning problem by applying a distributed optimization algorithm over an undirected and connected communication network. Each node has its own fuzzy logic system (FLS) based machine whose weights are trained by the proposed FLS-based distributed cooperative learning (DCL) algorithm to reach the optimum of the global cost function. The training process util...Show More
In this paper, we expand the scope of research on distributed cooperative learning (DCL) via fuzzy logic systems (FLSs) over an undirected and connected network, that is, each node (or learner) cooperatively learn an unknown pattern (or function) and finally reach consensus through local information interaction with their one-hop neighbors. Based on the approximation of FLSs, we present continuous...Show More
