In this work, a novel methodological approach to multi-attribute decision-making problems is developed and the notion of Heptapartitioned Neutrosophic Set Distance Measures (HNSDM) is introduced. By averaging the Penta-Partitioned Neutrosophic Distance Measures under particular conditional criteria, the suggested technique ranks the options. Additionally, we explore the fundamental characteristics of HNSDM and provide several illustrative theorems. The Heptapartitioned Neutrosophic Set Distance Measures are formulated based on the Hepta Neutrosophic Set. Lastly, a practical numerical example is provided to illustrate the efficacy of the suggested methodology. © 2025, University of New Mexico. All rights reserved.

Computing 2025年第6期107卷 1-38页

作者： Mashaqbeh, Husam S. Mjlae, Salameh A. Department of Computer Science Faculty of Information Technology Isra University Amman Jordan Department of Information Security and Cyberspace Faculty of Information Technology Isra University Amman Jordan Salt Jordan

Efficient task scheduling in Cloud Computing remains an NP-hard challenge due to combinatorial search spaces and resource heterogeneity, often leading to premature convergence in existing metaheuristics. This paper proposes FL-Jaya, an enhanced Jaya algorithm that addresses these limitations through two key innovations: (1) a Fitness-Distance Balance (FDB) mechanism, which preserves population diversity by selecting solutions that optimally trade off fitness quality and spatial distribution, and (2) a Lévy Flight (LF) operator, enabling stochastic long jumps to escape local optima. By unifying FDB and LF into a single update rule, FL-Jaya dynamically balances exploration and exploitation, overcoming stagnation in large-scale scheduling. Experiments on artificial (100–1000 tasks) and real-world Google Cloud Jobs datasets demonstrate FL-Jaya’s superiority over six algorithms—Jaya, Particle Swarm Optimization, Coati Optimization Algorithm, Whale Optimization Algorithm, Bald Eagle Search, and Snake Optimizer. FL-Jaya achieves 38.98% lower makespan and 44.63% higher average resource utilization (ARU) than standard Jaya on artificial workloads, with real-world results showing 35.34% makespan reduction and 44.63% ARU improvement. These gains stem from FL-Jaya’s ability to maintain solution diversity while navigating complex search spaces, outperforming peers in convergence speed and scalability. The algorithm’s parameter-light design and consistent performance underscore its practicality for heterogeneous cloud environments. © The Author(s), under exclusive licence to Springer-Verlag GmbH Austria, part of Springer Nature 2025.

Automating the grading of short answers in Indonesian presents unique challenges, primarily due to the inherent variability in student responses and the limited linguistic resources available for fine-tuning models. This study aims to develop an automated grading system for short answers by employing a modified BERT model tailored explicitly for the Indonesian language. Our methodology involves translating the Stanford Question Answering Dataset (SQuAD 2.0) and augmenting it with domain-specific content from lecture materials, resulting in an additional 1,000 question-answer pairs. Furthermore, we optimize the model using the Optuna library for hyperparameter tuning. Experimental results show a minimum loss of 1.81 for the model, with optimized hyperparameters including a learning rate of 3.36 × 10-5, a training batch size of 8 per device, and two training epochs. The model achieves an F1-score of 69%, demonstrating a satisfactory level of accuracy comparable to or slightly exceeding typical performances on SQuAD 2.0 in English, which averages around 66%. Evaluations were conducted across various scenarios, including short-answer, long-context, and long-answer assessments. The results revealed that short answers achieved the highest cosine similarity and a perfect QWK score of 1. In contrast, long-context and long-answer scenarios yielded a QWK of 0.5, indicating a need for further improvement;however, the model shows promise for long answers with additional enhancements. This study demonstrates BERT’s potential to enhance equity and precision in grading Indonesian short answers, despite limitations in response completeness. © (2025), (International Association of Engineers).

Advancements and challenges in privacy-preserving split learning: experimental findings and future directions

引用

International Journal of information Security 2025年第3期24卷 1-24页

Machine Learning (ML) has been extensively applied with remarkable success in various fields. However, training ML models using personal and/or private data has inadvertently revealed sensitive information and caused serious privacy risks. Consequently, Distributed Collaborative Machine Learning (DCML) has emerged as a promising approach to address such risks. Typically, DCML enables multiple entities to collaborate for training ML models with no disclosure of sensitive information. One of the most recent DCML techniques, namely Split Learning (SL), partitions the neural networks into a client and a server sub-network. Specifically, SL enables different entities to collaboratively train ML models and transmit the extracted features instead of sensitive raw data. Although SL prevents sending raw data to the server, the learned features may still reveal sensitive users’ information. This limitation has promoted Privacy-Preserving Split Learning (PPSL) which focuses on reinforcing data privacy within SL frameworks. This article represents a comprehensive survey on PPSL studies. It depicts relevant works published between 2018 and 2024. Moreover, the main objective of this research consists in identifying the key contributions of the state-of-the-art PPSL methods, in addition to investigating and comparing their performances. Accordingly, this survey supports the scientific community’s effort to bridge the research gaps and address challenges relevant to PPSL in resource-constrained environments. Furthermore, the findings of this survey highlight the importance of developing adaptive privacy protection techniques to brace future advancements in the field and strike a balance between data privacy and utility in the context of privacy-preserving split learning. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

ASR is an effectual approach, which converts human speech into computer actions or text format. It involves extracting and determining the noise feature, the audio model, and the language model. The extraction and determination of the noise feature is a crucial aspect of speech recognition, serving as both a process of information compression and signal deconvolution. ASR schemes are mostly employed in smart homes, smart appliances, and biometric schemes. Yet, traditional approaches offer very low performance because of a noisy environment. Moreover, local differences and accents negatively influence the ASR scheme execution during the conversion of the speech signals. This paper introduces a hybrid RMDL-CNN method to address these challenges. At first, the input of unclear speech is carried out by the dataset. Then, signal pre-processing is done by employing a Gaussian filter. After that, voice enhancement is accomplished by employing nonlinear spectral subtraction. Later, the speech word is segmented from the enhanced output based on the Attentional Encoder-Decoder approach and finally, the speech is recognized using the proposed RMDL-CNN. The RMDL-CNN method is devised by the combination of RMDL and CNN. Furthermore, the established RMDL-CNN is accessed for its efficiency based on several values of k-group value, as well as learning data. In addition, the introduced RMDL-CNN approach for speech recognition achieved better accuracy, PPV, as well as NPV of 0.909, 0.947, and 0.917 for dataset 1. Moreover, the RMDL-CNN has achieved the highest accuracy of 0.909, PPV of 0.926 and NPV of 0.888 for dataset 2. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2025.

Breast Cancer (BC) remains a critical global health challenge, accounting for millions of lives annually. Most breast cancer detection techniques are designed for binary classification. However, further classifying these types into their subtypes remains challenging due to cell coherence, variations in colour distribution, and intraclass similarity. Additionally, these techniques are limited to specific magnification levels of input images. As a result, the need to develop multiclass classification techniques independent of magnification levels has become increasingly demanding. This research introduces an innovative approach based on an enhanced vision transformer (ViT) for BC analysis that seamlessly handles binary and multiclass classification tasks in a magnification-independent manner. The proposed framework incorporates convolutional layers into the ViT model to simultaneously enhance its capability to capture local and global features. This innovative adjustment also empowers the model to capture complex patterns and subtle features by overcoming the issue of different magnification levels. Extensive experiments are conducted on the benchmark BreaKHis dataset to validate the effectiveness of the proposed framework. It achieves an accuracy of 89.43% for binary classification (benign vs. malignant) and 57.94% and 74.71% for multiclass benign and multiclass malignant subclass classification, respectively. The results confirm that the proposed framework surpasses the performance of the original ViT model and other state-of-the-art techniques. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

Recent data-intensive applications encounter memory wall bottlenecks in the traditional processor-centric computing architecture due to the need for frequent and extensive off-chip data movement. The emerging 3D-enabled near-memory processing (NMP) is a potential solution where computation can be offloaded and performed near memory, eliminating the need for expansive off-chip data transfer. Recently, some crucial works in this context have been proposed that use a supervised machine learning approach that requires a well-labeled dataset, which necessitates creating a time-consuming simulation process. Furthermore, their major focus was on profiling and offloading the entire application to the NMP side, causing a sub-optimal performance because of the low processing power on the NMP cores. This paper presents an unguided machine-learning-based approach (UCO) for computation offloading in NMP architecture that offloads only the memory-intensive regions of an application. The approach extracts several application performance characteristics and creates two clusters using them - one for the CPU side and another for the NMP side. The proposed approach's effectiveness is demonstrated through a series of comprehensive experiments with standard simulators and dataintensive benchmark applications. The results indicate that UCO improves performance (1.31x and 1.10x), saves energy (16% and 12%), and reduces off-chip data transfer (78% and 73%) compared to conventional and state-of-the-art approaches. © 2025 IEEE.

LLMs Encounter Critical Elements Prompts: Semantically Guided Partial Supervision Skeleton-Based Action Recognition

IEEE Sensors Journal 2025年第10期25卷 17350-17363页

作者： Xin, Wentian Liu, Yi Fu, Xianping Wang, Huibing Miao, Qiguang Liu, Ruyi Li, Long Pun, Chi-Man Dalian Maritime University School of Information Science and Technology Liaoning Dalian116026 China Xidian University School of Computer Science and Technology Shanxi Xi’an710071 China Guilin University of Electronic Technology Guangxi Key Laboratory of Trusted Software Guangxi Guilin541004 China University of Macau Faculty of Science and Technology Department of Computer and Information Science Macau China

Semantically guided skeleton-based action recognition is a crucial but challenging task in the data processing with RGB and depth sensors. The generation of action descriptions is facilitated by the pretrained language model, thereby imbuing the skeleton with essential contextual semantics. However, it also presents two challenges that require careful consideration: 1) efficiently and automatically generating the core semantics of actions and 2) extending the applicability of supervised learning when only partial labels are available. Therefore, we propose critical elements prompts for partial supervision in skeleton-based action contrastive learning (CEPCLR) as a significant attempt to break through the existing limitations of skeleton and semantic multimodal fusion. First, we design action-specific prompts that enable large language models (LLMs) to generate general semantic descriptions both efficiently and accurately, followed by iterative prompting that mines discriminative descriptions through controlled, rule-based emergence. Second, we adopt language-skeleton contrastive learning for multimodal fusion, which significantly enhances the integration of positive and negative action pairs. Notably, we introduce a novel partially supervised learning task for skeleton data, where labels are used selectively for semantic generation but are not involved in the classification tasks. The proposed CEPCLR achieves strong results on standard datasets like NTU RGB+D, NTU RGB+D 120, and PKU-MMD, effectively addressing missing contextual information in human skeleton and action expressions. © 2001-2012 IEEE.
