To address these challenges, we propose SFRN-LOPCOW-RAFSI, a novel multi-criteria decision making (MCDM) framework that combines spherical fuzzy rough numbers (SFRN), logarithmic percentage change-driven objective weighting (LOPCOW), and ranking of alternatives through functional mapping of criterion sub-intervals into a single interval (RAFSI). This study applies the proposed framework to a conceptual design evaluation case for a refrigerator service system, where four LLM-integrated service solutions are assessed based on 15 evaluation criteria. The methodology consists of three stages: (1) defining the problem structure, (2) computing the weight coefficients of the criteria using the SFRN-based LOPCOW method, and (3) ranking the design alternatives through the SFRN-based RAFSI approach. SFRN can represent a more extensive range of uncertainty and effectively handle uncertainty within the decision-making group, enhancing the reliability of the evaluation process. Sensitivity analysis and comparative analysis were conducted to validate the proposed method, confirming its robustness and effectiveness.

To address this issue, the present study proposes a Bayesian multi-objective optimization (MOO) framework integrating a multi-scale adaptive graph convolutional network (MAGCN) model and a multi-objective tree-structured Parzen estimator (MOTPE) algorithm. This framework aims to predict and optimize construction productivity and energy consumption performance while providing well-informed support for intelligent decision-making control. First, a hybrid feature selection method combining maximum information coefficient and Pearson correlation coefficient is applied to identify 6 key control parameters from 256 operational parameters. Second, an MAGCN model with multi-scale graph representation is proposed to establish the nonlinear mapping among geological conditions, operational parameters, construction productivity, and energy consumption. Third, the MOO framework with its mathematical formulation is constructed, and the Pareto optimal front for productivity and energy consumption is derived using the MOTPE-based Bayesian optimization algorithm. The optimal trade-off solution and corresponding operational parameters are determined by a weighted sum method. The proposed MOO framework is validated using operational data from the Tian Jing Hao CSD in the Pinglu Canal dredging project in China. The results show that the MAGCN model achieves high prediction accuracy for real-time productivity and energy consumption, with R<sup>2</sup> values of 0.942 and 0.979, respectively. The MOTPE-driven optimization reduces standard deviations of operational parameters by 21.24 % - 97.90 %, enhancing operational stability.

Identifying tumors in CT images manually is a time-intensive and complex task. While deep learning models can aid in the process, their complexity often leads to overfitting, and their single-branch, linear structures struggle to capture multi-scale features, ultimately reducing detection accuracy. This paper presents MACSENet, an innovative lightweight CNN developed to improve early detection and diagnostic accuracy using advanced deep learning techniques. The proposed model combines three key components: a standard CNN for basic feature extraction, a multiscale atrous convolutional module for capturing spatial features at different resolutions, and a squeeze-and-excitation (SE) block to refine channel-wise features through adaptive attention mechanisms. We designed the Multiscale Atrous Feature Extraction Block (MAFEB), which incorporates a multiscale atrous convolution module with varying dilation rates. This approach expands the receptive field without adding extra parameters, capturing intricate tumor details and providing a comprehensive contextual understanding to address the complex morphological variations in lung cancer. The SE block is applied after extracting features from the multiscale atrous convolution module, dynamically refining the feature maps by amplifying key diagnostic information and suppressing irrelevant details. To assess the broader applicability and generalizability of MACSENet, we evaluated it on the publicly available IQ-OTH/NCCD lung cancer dataset, which consists of 1097 CT images from 110 patients, encompassing benign, malignant, and normal cases. Additional experiments were carried out to evaluate the robustness of MACSENet using two other datasets: the Chest CT-Scan dataset, which consists of 1000 images across four classes, and the Lung histopathological images dataset, containing 15,000 images across three classes. The experimental results demonstrate that MACSENet outperforms both traditional deep CNNs and state-of-the-art methods in terms of accuracy and efficiency. Our approach achieved an outstanding accuracy of 99.55 % on the IQ-OTH/NCCD dataset, and 92 % and 99.97 % on the additional datasets while maintaining the smallest parameter size of 0.27 million among all competitors. Additionally, the model exhibited the smallest model size and FLOPS compared to other deep CNNs. Our proposed model is also compared with well-established baseline models including ResNet, DenseNet, and MobileNet series to demonstrate its superior performance in lung cancer detection. The proposed approach provides critical insights to support clinical decision-making for advancing patient care and treatment precision in lung cancer diagnostics.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"191 ","pages":"Article 114698"},"PeriodicalIF":6.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146080113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, a Physics-driven Feature Space Synthetic Minority Over-Sampling Technique (PFS-SMOTE) is introduced that augments minority-class samples in the feature space by incorporating physical prior knowledge, thereby improving the performance of intelligent fault-diagnosis models. Initially, a Neural Blind Deconvolution Mechanism (NBDM) is proposed, which utilizes adaptive fuzzy kernels optimized via complex frequency domain vectors to effectively extract fault impulse features. Next, we construct the Multi-Resolution Time-Frequency Convolution (MRTFConv) layer, utilizing Short-Time Fourier Transform-inspired kernels with adaptive Gaussian temporal envelopes and learnable oscillatory components for physically interpretable time-frequency representations. Building upon these innovations, a deep Siamese Network, integrating NBDM and MRTFConv, maps original data into a physically separable feature space, guided by a physics-informed loss function encompassing contrastive loss, time-frequency consistency loss, and fuzzy kernel consistency loss. Ultimately, PFS-SMOTE generates synthetic fault samples in this well-separated space, ensuring a balanced dataset.
