Joint Beamforming Design and Stream Allocation for Non-Coherent Joint Transmission in Cell-Free MIMO Networks

no code implementations28 Feb 2024 Xi Wang, Xiaotong Zhao, Juncheng Wang, You Li, Qingjiang Shi

We then propose a joint beamforming and linear stream allocation algorithm, termed as RWMMSE-LSA, which yields closed-form updates with linear stream allocation complexity and is guaranteed to converge to the stationary points of the original joint optimization problem.

Adaptive Federated Learning in Heterogeneous Wireless Networks with Independent Sampling

no code implementations15 Feb 2024 Jiaxiang Geng, Yanzhao Hou, Xiaofeng Tao, Juncheng Wang, Bing Luo

In this work, we advocate a new independent client sampling strategy to minimize the wall-clock training time of FL, while considering data heterogeneity and system heterogeneity in both communication and computation.

Counting Like Human: Anthropoid Crowd Counting on Modeling the Similarity of Objects

no code implementations2 Dec 2022 Qi Wang, Juncheng Wang, Junyu Gao, Yuan Yuan, Xuelong Li

The mainstream crowd counting methods regress density map and integrate it to obtain counting results.

Crowd Localization from Gaussian Mixture Scoped Knowledge and Scoped Teacher

no code implementations12 Jun 2022 Juncheng Wang, Junyu Gao, Yuan Yuan, Qi Wang

The core reason of intrinsic scale shift being one of the most essential issues in crowd localization is that it is ubiquitous in crowd scenes and makes scale distribution chaotic.

Delay-Tolerant Constrained OCO with Application to Network Resource Allocation

no code implementations9 May 2021 Juncheng Wang, Ben Liang, Min Dong, Gary Boudreau, Hatem Abou-zeid

We consider online convex optimization (OCO) with multi-slot feedback delay, where an agent makes a sequence of online decisions to minimize the accumulation of time-varying convex loss functions, subject to short-term and long-term constraints that are possibly time-varying.
