DaringFed: A Dynamic Bayesian Persuasion Pricing for Online Federated Learning under Two-sided Incomplete Information

no code implementations9 May 2025 Yun Xin, Jianfeng Lu, Shuqin Cao, Gang Li, Haozhao Wang, Guanghui Wen

To incentivize clients to participate in training by offering dynamic rewards to each arriving client, we design a novel Dynamic Bayesian persuasion pricing for online Federated learning (DaringFed) under TII.

One-Point Sampling for Distributed Bandit Convex Optimization with Time-Varying Constraints

no code implementations22 Apr 2025 Kunpeng Zhang, Lei Xu, Xinlei Yi, Guanghui Wen, Lihua Xie, Tianyou Chai, Tao Yang

Moreover, a reduced static network regret bound $\mathcal{O}( {{T^{2/3 + 4g /3}}} )$ is established for strongly convex local loss functions.

Decentralized Nonconvex Composite Federated Learning with Gradient Tracking and Momentum

no code implementations17 Apr 2025 Yuan Zhou, Xinli Shi, Xuelong Li, Jiachen Zhong, Guanghui Wen, Jinde Cao

Employing DFL methods to solve such general optimization problems leads to the formulation of Decentralized Nonconvex Composite Federated Learning (DNCFL), a topic that remains largely underexplored.

Performance Analysis of Distributed Filtering under Mismatched Noise Covariances

no code implementations13 Aug 2024 Xiaoxu Lyu, Guanghui Wen, Ling Shi, Peihu Duan, Zhisheng Duan

Additionally, we prove that the estimation error covariance of the consensus-based distributed filter under mismatched noise covariances can be bounded by the Frobenius norms of the noise covariance deviations and the trace of the nominal performance evaluation index.

Distributed Fractional Bayesian Learning for Adaptive Optimization

no code implementations17 Apr 2024 Yaqun Yang, Jinlong Lei, Guanghui Wen, Yiguang Hong

This paper considers a distributed adaptive optimization problem, where all agents only have access to their local cost functions with a common unknown parameter, whereas they mean to collaboratively estimate the true parameter and find the optimal solution over a connected network.
