The importance of comprehending these behaviours is acknowledged, leading us to propose an innovative decision-making support model that integrates the analytic hierarchy process (AHP) with the best worst method (BWM) in a fuzzy context. Our objective is to effectively evaluate the overall influence of driver behaviour on road safety while reducing ambiguity in assessments. In a practical case study involving skilled drivers in Budapest, Hungary, a thorough survey was conducted to prioritise key driving behaviour factors that impact road safety. Our findings reveal ‘errors’ as the most vital aspect, followed by specific behaviours like ‘colliding when reversing without observation’ and ‘driving under the influence of alcohol’. By simplifying the survey procedure and offering practical insights, our unified model improves decision-making for policymakers striving to tackle road safety issues efficiently. To conclude, our research showcases the effectiveness of merging AHP and BWM methodologies in a fuzzy setting to obtain valuable perspectives on road safety concerns, ultimately aiding in the advancement of sustainable transportation systems.</p>","PeriodicalId":51053,"journal":{"name":"Expert Systems","volume":"42 9","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exsy.70104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is essential to achieve privacy-aware crowd counting and to solve the problem of scale variation in dense scenes. To this end, we propose a Privacy-preserving Quantum-enhanced Network (PQNet). The PQNet uses federated learning to share parameters rather than data, which ensures the privacy of each client. Subsequently, a multi-scale quantum-driven calibration module is designed to capture multi-scale information via quantum states. It enhances counting accuracy in dense crowd environments where scale varies.

Surprise is a biological trait inherent in humans and animals and is essential for many creative acts and efforts of discovery. Numerous technical domains are comprised of discrete elements in sequences such as e-commerce transactions, genome data searching, online financial transactions of many types, criminal cyber-attacks and life-course data from sociology. In addition to the complexity and computational burden of this type of problem is the issue of their rarity. Many anomalies are infrequent and may defy categorisation; therefore, they are not suited to classification solutions. We test our methods on four discrete datasets (Hospital Sepsis patients, Chess Moves, the Wisconsin Card Sorting Task and BioFamilies) consisting of discrete sequences. Probabilistic Suffix Trees are trained on this data which maintain each discrete symbol's location and position in a given sequence. The trained models are exposed to “new” data where any deviations from learned patterns either in location on the sequence or frequency of occurrence will denote patterns that are unusual compared with the original training data. To assist in the identification of new patterns and to avoid confusing old patterns as new or novel we use Bayesian surprise to detect the discrepancies between what we are expecting and actual results. We can assign the degree of surprise or unexpectedness to any new pattern and provide an indication of why certain patterns are deemed novel or surprising and why others are not.</p>","PeriodicalId":51053,"journal":{"name":"Expert Systems","volume":"42 9","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exsy.70106","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study applies artificial intelligence techniques to a domain-specific problem that has traditionally relied on expert judgement: the generation of detailed construction schedules for photovoltaic power plants. As renewable generation is a key part to meet the challenges of energy transition, the implementation of large projects has increased in recent years and this trend is expected to continue in the future. The main difficulty in meeting construction deadlines is the elaboration of an adequate planning. A tool that automatically generates schedules can be of great help to set up an initial baseline planning. To this end, this work compares five artificial intelligence techniques, on a data set consisting of real examples of successfully completed projects. The evaluation of the results obtained on test data shows that Adaptive Neuro-Fuzzy Inference System (ANFIS) is the technique that obtains the best performance in all error metrics, although it entails a high computational cost. The model thus obtained manages to generate a complete construction schedule with an error of 8% of the total duration. The use of metrics as MAE, MSE and <span></span><math>\u0000 <semantics>\u0000 <mrow>\u0000 <msup>\u0000 <mi>R</mi>\u0000 <mn>2</mn>\u0000 </msup>\u0000 </mrow>\u0000 <annotation>$$ {R}^2 $$</annotation>\u0000 </semantics></math> provides a robust understanding of prediction accuracy, variability, and fit. These metrics are commonly used in project planning evaluations and help interpret model behaviour under different error profiles. Additionally, the resulting 8% total duration error implies a deviation of around 24 days in a 300-day project, which is highly actionable in real-world solar project management. The findings not only demonstrate the feasibility of using AI for solar construction planning, but also lay the groundwork for the development of intelligent software tools or platforms that could support planners in the renewable energy sector. While this study focuses on photovoltaic plants, the approach is extendable to other power plants as wind farms, combined-cycle or nuclear plants, or even to other construction projects.</p>","PeriodicalId":51053,"journal":{"name":"Expert Systems","volume":"42 9","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exsy.70105","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These images are captured under an uncontrolled environment (e.g., viewpoint and illumination changes); therefore, such type of data is extremely challenging in Content-Based Image Retrieval (CBIR) research. Even in Google searches, most of the time the query results are provided with inaccurate results or duplicate results due to the minor variations between apparel. Another major challenge is that the extracted feature vector dimensions are too high and difficult to handle. In this paper, a method named Multifeature Representation with Maximum Correlation-based Feature Fusion, and Matching (MFR-MCF<sup>2</sup>M) is proposed for apparel retrieval. This method consists of three modules: (1) Multifeature Representation Module (MFR-M), (2) Maximum Correlation-based Feature Fusion Module (MCF<sup>2</sup>-M) and (3) Multifeature Matching Module (MFM-M). In the MFR module, the shape, texture and deep features of apparel images are extracted using a Histogram of Oriented Gradients (HOG), Local Binary Patterns (LBP) and a pretrained deep CNN model, respectively. Also, the dimensionality of extracted features is reduced using the proposed Feature Subselection (FSS) method. The MCF module is implemented to measure the maximum correlation between reduced feature vectors. Finally, MCF<sup>2</sup> is performed using Euclidean distance and a generated Feature Correlation Vector (FCV) to improve the retrieval accuracy and as the benchmark to assess the efficacy of the proposed method. In addition, a new large-scale dataset named Apparel Images Gallery (AIG), which consists of 130,000 images, has been provided to the community. The performance of the proposed MFR-MCF<sup>2</sup>M method is evaluated on three datasets, including two publicly available datasets and the proposed AIG dataset. The retrieval results are obtained after passing through the threshold function of both the Euclidean distance and the computed FCV. The proposed method achieved an accuracy of 78.3% on the clothing dataset, 94.8% on the CR dataset and 89.1% on the proposed AIG dataset. Consequently, the MFR-MCF<sup>2</sup>M outperformed state-of-the-art (SOTA) apparel retrieval methods.</p>","PeriodicalId":51053,"journal":{"name":"Expert Systems","volume":"42 9","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exsy.70097","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144673198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, deep learning models have been substantial in automatically extracting intrinsic emotional features with greater accuracy across multiple modalities. The proposed article presents a comprehensive review of recent progress in emotion detection, spanning from unimodal to multimodal systems, with a focus on facial and speech modalities.

To address these challenges, we propose the multi-scale gated temporal and spatial attention network (MGTSA-Net).

Its primary objective is to identify unusual deviations in the test set by capturing the typical behavioral patterns of timing data. Despite their strong detection capabilities when labeled data is not available, current reconstruction-based approaches still struggle with anomalous interference and inadequate semantic information extraction at higher time series levels. To tackle these problems, we provide a multi-scale dual-domain patch attention contrast learning model (DMAP-DDCL) that incorporates adaptive path selection and adaptive dynamic context-aware masking. Dynamic context-aware masks are specifically used by DMAP-DDCL to improve the model's generalization ability and mitigate bias resulting from the influence of anomalous data during training. Multi-scale patch segmentation and dual attention to the segmented patches are introduced to capture local details and global correlations as time dependencies. By enlarging the contrast between the two data perspectives, global and local, DMAP-DDCL improves the capacity to differentiate between normal and abnormal patterns. In addition, we enhance the adaptive path of the multi-scale bi-domain attention network, which adapts the multi-scale modeling process to the temporal dynamics of the inputs and enhances the model's accuracy. According to experimental results, DMAP-DDCL performs better on five real datasets from various domains than eight state-of-the-art baselines.
