Federated Learning (FL) has significant potential to protect data privacy and mitigate network burden in mobile edge computing (MEC) networks. However, due to the system and data heterogeneity of mobile clients (MCs), client selection and bandwidth allocation is key for achieving cost-efficient FL in MEC networks with limited bandwidth. To address these challenges, we investigate the issue of joint client selection and bandwidth allocation for reducing the cost (i.e., latency and energy consumption) of FL training. We formulate the problem and decompose it into a holistic subproblem to reduce the number of rounds and a partial subproblem to reduce the costs of FL each round. We propose a joint class-balanced client selection and bandwidth allocation (CBCSBA) framework to address the whole problem. Specifically, for the holistic subproblem, CBCSBA combines MCs into groups, each having data distribution as close as possible to class-balanced distribution;For the partial subproblem, CBCSBA reduces costs by exploratively selecting a group and sequentially optimizing the latency and energy consumption of MCs within the group. Experimental results show that CBCSBA outperforms the baseline frameworks in reducing latency by 28.2% and energy consumption by 25.3% on average in the considered four datasets. © 2002-2012 IEEE.

The process of research activities in the electric power field produces a large number of articles, patents, and other results, which contain a large amount of information. Named entity recognition is a common method for obtaining textual information, and this study establishes a model that can efficiently recognize named entities of electric power research results. Firstly, the keywords of electric power literature are obtained for preprocessing and organization, and then the annotated dataset of keyword named entities of electric power scientific research is constructed. After that, this paper enhances the ability of the model to obtain contextual information through the Transformer encoder and enriches the expression of textual information by obtaining textual semantic structure information through dependent syntactic analysis. Meanwhile, in order to strengthen the feature extraction ability, the BILSTM-Multi-Head-Attention-CRF model is used to obtain text context information. IDCNN model is also used to make this paper's model acquire the ability to extract text semantic structure information. Finally, ablation experiments are conducted to show that the model proposed in this paper has a better recognition effect compared with the named entity recognition methods in the generic domain. © 2023 IEEE.

The global elderly population is increasing rapidly, leading to a rise in chronic illnesses and co-existing conditions, which in turn results in higher healthcare expenses. Accidental falls are among the leading causes of injury-related deaths in elderly individuals. This study aims to create a real-time monitoring system using vital signs to foresee a future fall in older adults by identifying abnormalities through continuous monitoring. The proposed fall prediction technique, employing the Fuzzy-based Fall Prediction Algorithm, utilizes Fuzzy rules to learn and execute tasks. The obtained results are then classified according to different levels of predicted risk indicators. The developed model is tested using data from older adults sourced from a public repository and compared with the results of the theoretical evaluation. The simulated outcomes demonstrate that the proposed algorithm achieves 96% accuracy, 93.75% sensitivity, and 100% specificity. Utilizing these advancements in the proposed heterogeneous technology allows for the early prediction of falls in the elderly and can potentially save lives. © 2024 IEEE.

In the information age, the electric power industry, as a crucial pillar of modern society, has accumulated a wealth of valuable research literature. Knowledge graph technology offers the potential to tap into this knowledge repository, providing a better understanding of research outcomes in the electric power domain. However, due to the diversity and complexity of knowledge in the power industry, it is difficult to build a comprehensive and complete knowledge graph of power keywords. In recent years, large language models (LLMs) have made significant advancements. This paper harnesses LLM technology along with text similarity analysis and co-occurrence frequency analysis to establish a comprehensive framework for processing keyword knowledge in the field of electric power. Within this framework, various forms of information found in electric power research can be processed. This includes creating a thesaurus of electric power domain keywords;obtaining the individual attributes implied by the information keywords in this thesaurus and their interconnections;and generating a knowledge graph of electric power domain keywords. This knowledge graph includes attributes, interpretations, relationships, and associated literature for keywords. It serves as a valuable reference for the effective utilization of research outcomes in the electric power domain. © 2023 IEEE.

Molecular subtyping of cancer is recognized as a critical and challenging upstream task for personalized therapy. Existing deep learning methods have achieved significant performance in this domain when abundant data samples are available. However, the acquisition of densely labeled samples for cancer molecular subtypes remains a significant challenge for conventional data-intensive deep learning approaches. In this work, we focus on the few-shot molecular subtype prediction problem in heterogeneous and small cancer datasets, aiming to enhance precise diagnosis and personalized treatment. We first construct a new few-shot dataset for cancer molecular subtype classification and auxiliary cancer classification, named TCGA Few-Shot, from existing publicly available datasets. To effectively leverage the relevant knowledge from both tasks, we introduce a task-specific embedding-based meta-learning framework (TSEML). TSEML leverages the synergistic strengths of a model-agnostic meta-learning (MAML) approach and a prototypical network (ProtoNet) to capture diverse and fine-grained features. Comparative experiments conducted on the TCGA FewShot dataset demonstrate that our TSEML framework achieves superior performance in addressing the problem of few-shot molecular subtype classification. © 2024 IEEE.

Chaotic Evolution (CE) is a significantly faster and more robust method for solving single-objective and multi-objective optimization problems. However, there are various factors that can impact the performance of CE, with population initialization being one of them. A well-executed initialization method can contribute to the discovery of better solutions and enhance both convergence rate and accuracy. This paper conducts a comparative experiment on CE algorithms using six different initialization methods. The performance of the CE algorithms utilizing these various initialization methods is analyzed and discussed. To assess convergence rate and accuracy, eight single-objective optimization benchmark functions and five multi-objective optimization benchmark functions are employed in our analysis. The evaluation results reveal significant disparities among the six initialization methods, indicating that different approaches to initialization have a substantial influence on the optimization performance of the CE algorithm. © 2024 IEEE.
