Motivated by the complex dynamics of cooperative and competitive interactions within networked agent systems, multi-cluster games provide a framework for modeling the interconnected goals of self-interested clusters of agents. For this setup, the existing literature does not provide comprehensive gradient-based solutions that simultaneously address constraint sets and directed communication networks-both of which are essential for many practical applications-due to the complexities posed by the projection and the imbalanced mixing matrix. To address this gap, this paper proposes a distributed Nash equilibrium seeking algorithm that integrates consensus-based methods and gradient-tracking techniques, utilizing row-stochastic weight matrices for inter-cluster communication and column-stochastic weight matrices for intracluster communication. To handle constraints, we introduce an averaging procedure to control errors introduced by projection methods within the gradient-tracking procedure. We establish the linear convergence of the proposed algorithm, focusing on the contraction property of the optimality gap. The efficacy of the algorithm is demonstrated through its application to microgrid energy management. © 2024 IEEE.

In this paper, a new scheduling model is presented to speed up the logistics processing in an automatic cube storage warehouse. Automated guided vehicles (AGV) are used to move all items in the warehouse according to the computer's instructions. The tasks to be performed by the AGV are optimally distributed using Genetic Algorithms (GA). The goal of our research is to optimize order scheduling in automatic warehouses to reduce human resources and lower the cost of logistics. The proposed GA's fitness function reflects removing the stacked bin, a cube storage warehouse characteristic, and getting the designated bin. Through extensive computer simulations, it is shown that the higher the generation of the GA we design, the lower the logistics processing time. As compared with other meta-heuristic optimization algorithms, our proposed GA algorithm demonstrates a maximum of 21% reduction in delivery time. © 2023 IEEE.

As the scale of micro-service systems on the cloud continues to expand, the dependencies between micro-services become more and more complex. Service anomalies may continue to propagate with the call relationship, leading to a decrease in the overall availability of the system. In order to cope with large-scale micro-service systems with complex dependencies, this paper designs an anomaly location method MicroALLS suitable for large-scale micro-services. This method collects micro-service operation indicator data based on Istio;uses the anomaly detection module of the variational auto-encoder for anomaly detection;once an anomaly is detected, an improved random walk algorithm is used to accurately and efficiently locate the micro-service anomaly. We use the train-ticket micro-service system as a test environment to evaluate the positioning accuracy of this method. The experimental results show that the anomaly detection and accuracy of the method are improved compared with the comparison method. © 2024 IEEE.

Owing to the wide application of lithium-ion batteries in industry, it is of great significance for accurate prediction of battery state of health (SOH) to ensure the safety and stability of equipment. The battery capacity regeneration (CR) during capacity degradation affects the accuracy of capacity prediction. This study proposes a hybrid estimation method for state of health of lithium-ion batteries based on linguistic description (LD) considering capacity regeneration. First, the capacity degradation data is decoupled into the trend component and the capacity regeneration component by the variational mode decomposition (VMD). Second, in order to improve the accuracy and reliability of battery capacity prediction, the capacity regeneration part is described by linguistic description. Finally, the trend part and the linguistic description sequence of capacity regeneration are predicted by support vector regression (SVR) model and long short term memory network with attention mechanism (Attn-LSTM) respectively, and their forecast results are superposed as the battery capacity prediction. The experimental results in NASA battery data demonstrate the effectiveness of the proposed method. © 2023 IEEE.

Femtocell network has a great development space in increasing coverage and capacity of wireless network. In order to meet the quality of service (QoS) requirements of MUEs in MBS coverage, we propose a seed channel incentive mechanism in the two-tier femtocell network, where the MBS provides sub-channels to FBSs to motivate them to serve for the MUEs within the MBS coverage. To maximize the energy efficiency of femtocell layer after hybrid access, the optimization problem is modeled. The combined method of worst-case, Dinkelbach and continuous convex approximation is developed to make the optimization problem solvable. In addition, in order to realize the practical application of the proposed scheme, an optimization algorithm combining sub-channel and power allocation is developed. The numerical results show that the proposed algorithm is effective in improving the energy efficiency of the femtocell layer. © 2023 IEEE.

Federated learning (FL) is a promising distributed machine learning technique for solving the privacy leakage problem in machine learning training process. Multiple parties collaborate to train a machine learning model, while the data is kept locally, so as to achieve privacy-preservation of users. However, some studies have shown that an attacker can infer some sensitive information from the interacted data, even if the raw data is not available. It is necessary to adopt some privacy-preserving techniques such as secure multi-party computation and homomorphic encryption to prevent the above problem. Most existing solutions have focused on FL over horizontally partitioned data but ignore the research on FL over vertically partitioned data. In this paper, we present a vertical federated learning scheme with enhanced privacy preservation. Split learning is used to enable cooperative neural network training between multiple parties with vertically partitioned datasets, and a hybrid secure two-party computation protocol is adopted for protecting users’ privacy. The experimental results demonstrate the feasibility of our scheme. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Semi-supervised learning (SSL) is a successful paradigm that can use unlabelled data to alleviate the labelling cost problem in supervised learning. However, the excellent performance brought by SSL does not transfer well to the task of class imbalance. The reason is that the class bias of pseudo-labelling further misleads the decision boundary. To solve this problem, we propose a new plug-and-play approach to handle the class imbalance problem based on a theoretical extension and analysis of distribution alignment. The method, called Basis Transformation Based Distribution Alignment (BTDA), efficiently aligns class distributions while taking into account inter-class *** implements the basis transformation through a learnable transfer matrix, thereby reducing the performance loss caused by pseudo-labelling biases. Extensive experiments show that our proposed BTDA approach can significantly improve performance in class imbalance tasks in terms of both accuracy and recall metrics when integrated with advanced SSL algorithms. Although the idea of BTDA is not complex, it can show advanced performance on datasets such as CIFAR and SVHN. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
