This exploratory study used qualitative semi-structured interviews (<i>N</i> = 21) and then quantitative analysis (<i>N</i> = 629) to predict user motivators and detractors to AI adaptation. Fifty-eight percent of respondents in this study did not agree that AI will benefit our society. There was a significant difference those identified as highly feminine and the highly masculine. Those politically conservative were less likely to support AI initiatives than those politically liberal. Independent variables were factored into latent themes “Ethical Outcomes”, Social Media Risk vs. Reward”, and “Governmental Constraint.” Ethical Outcomes was the key significant predictor of “trust AI with my personal and business activities.” The effect of Social Media Risk was marginal but significant. Logistic regression with the dependent variable “overall, artificial intelligence will benefit our society” once again captured Ethical Outcomes. The concern for social media implications was 19% more likely to be considered when pondering beneficence of AI in society. Governmental Constraint was 70% more likely to occur. When AI is considered as a future religious entity, users perceive a decrease in benefit to society. A hierarchical decision tree with the target variable “trust related to AI” illustrates users first consider ethical implications of AI in society, and then face dilemmas of copyright infringement and effect on political elections.</p></div>","PeriodicalId":72089,"journal":{"name":"Advances in computational intelligence","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43674-026-00088-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147561761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by developing and validating lightweight deep learning models specifically optimized for edge device deployment, enabling real-time ECG analysis in remote and under-resourced healthcare environments. Utilizing the MIT-BIH Arrhythmia Dataset, which includes 48 half-hour ECG recordings from 47 individuals, we trained and evaluated 2 models: a standard Convolutional Neural Network (CNN) and a computationally efficient Depth-Wise Separable Convolutional Neural Network (DWCNN). Preprocessing involved segmenting ECG recordings into individual heartbeats and addressing class imbalance through downsampling, resulting in a balanced dataset of 21,186 images across 6 arrhythmia types. The DWCNN achieved competitive diagnostic performance (precision: 0.97, recall: 0.97) while utilizing 75% fewer parameters than the standard CNN (8.45 M vs. 34.08 M) and 65% less memory (8.4 MB vs. 24.1 MB).

This research introduces a groundbreaking automated system for DR detection and severity classification. First, we collected the corresponding data and applied advanced preprocessing techniques such as resizing image, normalization, Gaussian blur, contrast limited adaptive histogram equalization (CLAHE), and image blending to improve model performance. Furthermore, we employed powerful deep learning (DL) architectures such as VGG, EfficientNet, DenseNet, ResNet50, and transformer models such as vision transformer (ViT), and swin transformer for feature extraction.

Kepler optimization algorithm (KOA) is a novel metaheuristic algorithm that performs well in solving optimization problems on continuous domains, but cannot be directly applied to solve combinatorial optimization problems on discrete domains. In order to design more transfer functions and solve combinatorial optimization problems by KOA, this paper first proposes a practical method to construct transfer functions. From this, two new classes of transfer functions are given: A-shaped transfer functions and B-shaped transfer functions. Then, based on the transfer function, the first discrete Kepler optimization algorithm (DKOA) suitable for binary optimization problems is proposed. To verify the practicality of the new transfer functions and the efficiency of DKOA, DKOA is used to solve 0–1 knapsack problem and knapsack problem with a single continuous variable, respectively. Comparison with existing transfer functions and the state-of-the-art metaheuristic algorithms for solving these two problems shows that DKOA using A-shaped and B-shaped transfer functions is more competitive in terms of the ability to obtain optimal solutions, average performance and stability. This shows that the proposed new transfer functions are very practical, and the DKOA based on them is an effective metaheuristic algorithm for solving binary optimization problems.</p></div>","PeriodicalId":72089,"journal":{"name":"Advances in computational intelligence","volume":"5 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145561074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes an innovative forecasting architecture based on Gaussian process regression (GPR), whose hyperparameters are estimated via a Bayesian inference procedure, enabling the model to adapt in real time to latent market fluctuations and previously unobserved structural shifts. By integrating these evolving characteristics, our approach more accurately captures changes in China’s PPI trajectory. The empirical analysis relies on a monthly dataset spanning October 1996 to February 2025, covering multiple waves of regulatory reform, industrial evolution, and macroeconomic transformation. Validation is performed over an out-of-sample period from June 2019 through February 2025, producing a relative root mean square error of 0.1120%, a root mean square error of 0.1131, a mean absolute error of 0.0832, and a correlation coefficient of 0.99984. To the best of our knowledge, this represents the first application of a Bayesian-inference-parameterized GPR model to forecast China’s PPI for production materials.

One of the primary challenges in AGV deployment is achieving precise navigation to ensure task reliability, safety, and efficient battery consumption along predetermined routes. Vision-based methods have gained significant attention for their high performance in robot navigation. However, selecting the most effective algorithm with minimal sensor use remains an active area of research. This study introduces a novel and efficient fusion-based navigation method, termed the Extended Fusion 1 Method (EFM1), which integrates data from camera and infrared (IR) sensors. The system leverages feature-based algorithms, such as SIFT, ORB, FAST, SURF, BRISK, and BRIEF, to improve path-tracking accuracy. The main objective of this fusion approach is to enhance navigational precision and identify the most suitable algorithm for robust AGV path-tracking. The EFM1 method is simulated and validated using the CoppeliaSim (V-REP) simulator, incorporating the real-world dimensions of the previously developed AGV model, Hongma, via Python API. The simulation evaluates six feature-based algorithms across five distinct path types: circular, elliptical, spiral, figure-eight, and custom path. Performance is assessed in terms of maximum achievable speed, minimal path-tracking error, body orientation accuracy, and simulation time. Statistical analysis, including inferential techniques and post hoc tests, is used to interpret the results. The experimental findings demonstrate that the proposed EFM1 algorithm outperforms traditional vision-only approaches in effectively tracking all five path types, confirming its potential for reliable and efficient AGV navigation. The proposed EFM1 algorithm integrates vision and IR sensors, enhancing AGV navigation accuracy by up to 84% while using minimal sensors. It outperforms previous methods by delivering up to 22.2% faster simulation times, significantly reduced error rates (for example, ORB error decreased by 93%), and increased speed across five test paths. The comparison between investigated methods shows that FAST excels on dynamic paths with notable speed improvements, while SURF performs better on complex trajectories as confirmed by statistical analysis. Although EFM1 improves most metrics, body orientation changes increased, indicating a trade-off between agility and movement stability.</p></div>","PeriodicalId":72089,"journal":{"name":"Advances in computational intelligence","volume":"5 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145384942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
