Stock price prediction is a challenging research domain. The long short-term memory neural network (LSTM) widely employed in stock due to its ability address long-term dependence and transmission of historical time signals series data. However, manual tuning LSTM parameters significantly impacts model performance. PSO-LSTM leveraging PSO’s efficient swarm intelligence strong optimization capabilities proposed this article. experimental results on six global indices demonstrate that effectively fits real data, achieving high accuracy. Moreover, increasing PSO iterations lead gradual loss reduction, which indicates PSO-LSTM’s good convergence. Comparative analysis with seven other machine learning algorithms confirms the superior performance PSO-LSTM. Furthermore, impact different retrospective periods accuracy finding consistent across varying spans are. Conducted experiments.

This paper aims to solve the scheduling optimization problem in emergency management of long-distance natural gas pipelines, with goal minimizing total time. To this end, objective function minimum time is established, and relevant constraints are set. A model based on particle swarm (PSO) algorithm proposed. In view high-dimensional complexity local optimal problems, neighborhood adaptive constrained fractional (NACFPSO) used it. The experimental results show that compared traditional algorithm, NACFPSO performs well both convergence speed time, an average 81.17 iterations 200.00 minutes; while 82.17 207.49 minutes. addition, increase pipeline complexity, can still maintain its advantages especially which further verifies effect management.

Neural Computing and Applications, Год журнала: 2024, Номер 36(24), С. 14727 - 14756

Опубликована: Май 10, 2024

Abstract This study explores crop yield forecasting through weight agnostic neural networks (WANN) optimized by a modified metaheuristic. WANNs offer the potential for lighter with shared weights, utilizing two-layer cooperative framework to optimize network architecture and weights. The proposed metaheuristic is tested on real-world datasets benchmarked against state-of-the-art algorithms using standard regression metrics. While not claiming WANN as definitive solution, model demonstrates significant in lightweight architectures. models achieve mean absolute error (MAE) of 0.017698 an R -squared ( $$R^2$$ R 2 ) score 0.886555, indicating promising performance. Statistical analysis Simulator Autonomy Generality Evaluation (SAGE) validate improvement significance feature importance approach.

Cloud computing offers scalable and adaptable resources on demand, has emerged as an essential technology for contemporary enterprises. Nevertheless, it is still challenging work to efficiently handle cloud because of dynamic changes in load requirement.
