Therefore, this problem is typically modeled as a multi-objective optimization problem and can be solved using multi-objective evolutionary algorithms (MOEAs). However, feature selection based on weights derived from preferences may lead to the exclusion of specific features, thereby impacting classification performance. Furthermore, if duplicate individuals are not adequately addressed during the evolutionary process, it may adversely affect the convergence and diversity of the population. In this paper, we propose a multi-objective evolutionary algorithm for feature selection incorporating dominance-based initialization and duplication analysis. To filter features impartially, we transform the correlation issues among features, as well as those between features and labels, into a multi-objective optimization problem by assigning corresponding weights based on their dominance relationships. In addressing the duplication problem within the evolutionary process, the disparity between duplicate individuals as well as between duplicate individuals and elite solutions is analyzed to systematically eliminate redundancy. In the experiments, the proposed method was compared with two classical algorithms and three feature selection algorithms across thirteen datasets.

Our key technical innovation is to train a small neural network to fit quadrature points for robust numerical integration on implicit grid cells. When coupled with a Mixed Finite Element formulation, this yields a smooth, fully differentiable simulation model connecting the evolution of the underlying implicit surface to its elastic response.

Monitoring motor disabilities frequently observed in PD is difficult for physicians, as they are limited to the information observed or self-reported during routine consultations, resulting in subjectivity and limited assessment. Thus, it is necessary to evaluate more frequently and objectively, ideally in a continuous manner including daily life tasks. While wearable sensory devices, such as inertial sensors, and their applications are steadily growing, the advances in artificial intelligence studies have revolutionized their ability to extract deeply hidden information for accurate detection and interpretation of motor activities. However, further studies are required, mainly focused on PD. This study aimed to implement a deep learning (DL) based model for recognizing daily motor activities based on inertial data to contribute to PD. The model relied on a convolutional neural network (CNN) architecture, trained and tested on a created custom dataset. We further benchmarked our model against other popular DL frameworks. The dataset included inertial data captured from 18 patients while performing trivial quotidian tasks, such as walking, turning, sitting, and lying. We hypothesized that a DL model based on a CNN architecture could be an appropriate solution for modeling daily motor non-steady and steady-state tasks from a single inertial sensor. We measured an F1 score of 0.906 and an accuracy of 91.1 % on final testing with our optimized CNN model, being the tasks of standing and walking the most accurately recognized by the model.

Addressing these challenges is crucial for developing robust and accurate food recognition systems, which have applications in health monitoring, dietary assessment, and automated food logging. This study aims to tackle these issues by employing ensemble learning and knowledge distillation. We use ensemble learning to effectively combine the local perception capability of convolutional neural networks (CNNs) and the global modeling capability of Vision Transformers. The synergistic ensemble enhances the model's ability to discern subtle differences within categories and capture a spectrum of diverse patterns across various categories. To reduce the number of base models in an ensemble, we employed a method combining knowledge distillation and re-ensembling. Specifically, we used the collective knowledge of four base models to guide the re-learning process of student models. Subsequently, we re-ensembled these distilled models, significantly enhancing the recognition performance of the ensemble while maintaining the same computational efficiency. Finally, we fine-tuned the optimal ensemble weights to further boost the recognition performance of the ensemble model. We conducted extensive experiments on the large-scale food datasets Food2k and CNFood241, achieving state-of-the-art performance.

This work proposes Fuzzy Logic Controllers (FLC) for steering of an autonomous vehicle. A fuzzy controller does not need for a certain model to steer the vehicle. However, the rules and membership functions should be determined with the aid of an expert. Here, with the purpose of getting one step close to the automatically tunable fuzzy control systems, the Artificial Bee Colony (ABC) algorithm is utilized on tuning the output membership functions of the FLC. Three different fuzzy controllers are developed for an autonomous vehicle. The first one is provided from the literature, two others are developed with the help of ABC algorithm. The base widths of the output membership functions of two other fuzzy controllers are determined by using cost functions of the Integral of Absolute Error (IAE) and the Integral of Time Absolute Error (ITAE). The performances of the developed controllers are evaluated through the results of various simulation studies, keeping in view performance indicators such as overshoot, settling time and Mean Squared Error (MSE). The results demonstrate superiority of the controllers proposed in this work to the reference one (the first fuzzy controller). Finally, this work reveals that the parameters of the fuzzy controller devised to steer an AGV can be tuned by using metaheuristic optimization algorithms.</div></div>","PeriodicalId":50523,"journal":{"name":"Engineering Applications of Artificial Intelligence","volume":"151 ","pages":"Article 110642"},"PeriodicalIF":7.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
