Accurate classification of electromyographic (EMG) signals is vital in biomedical applications. This study evaluates different architectures recurrent neural networks for the EMG associated with five movements right upper extremity. A Butterworth filter was implemented signal preprocessing, followed by segmentation into 250 ms windows, an overlap 190 ms. The resulting dataset divided training, validation, and testing subsets. Grey Wolf Optimization algorithm applied to gated unit (GRU), long short-term memory (LSTM) architectures, bidirectional networks. In parallel, a performance comparison support vector machines (SVMs) performed. results obtained first experimental phase revealed that all RNN evaluated reached 100% accuracy, standing above 93% achieved SVM. Regarding speed, LSTM ranked as fastest architecture, recording time 0.12 ms, GRU 0.134 Bidirectional showed response 0.2 while SVM had longest at 2.7 second phase, slight decrease accuracy models observed, 98.46% LSTM, 96.38% GRU, 97.63% network. findings this highlight effectiveness speed task.

Modeling Short-Term Drought for SPEI in Mainland China Using the XGBoost Model

Atmosphere, Год журнала: 2025, Номер 16(4), С. 419 - 419

Accurate drought prediction is crucial for optimizing water resource allocation, safeguarding agricultural productivity, and maintaining ecosystem stability. This study develops a methodological framework short-term forecasting using SPEI time series (1979–2020) evaluates three predictive models: (1) baseline XGBoost model (XGBoost1), (2) feature-optimized variant incorporating Pearson correlation analysis (XGBoost2), (3) an enhanced CPSO-XGBoost integrating hybrid particle swarm optimization with dual mechanisms of binary feature selection parameter tuning. Key findings reveal spatiotemporal patterns: temporal-scale dependencies show all models exhibit limited capability at SPEI-1 (R2: 0.32–0.41, RMSE: 0.68–0.79) but achieve progressive accuracy improvement, peaking SPEI-12 where attains optimal performance 0.85–0.90, 0.33–0.43) 18.7–23.4% error reduction versus baselines. Regionally, humid zones (South China/Central-Southern) demonstrate peak (R2 ≈ 0.90, RMSE < 0.35), while arid regions (Northwest Desert/Qinghai-Tibet Plateau) dramatic improvement from 0.35, > 1.0) to 0.85, 52%). Multivariate probability density confirms the model’s robustness through capture nonlinear atmospheric-land interactions reduced parameterization uncertainties via intelligence optimization. The CPSO-XGBoost’s superiority stems synergistic optimization: enhances input relevance adaptive tuning improves computational efficiency, collectively addressing climate variability challenges across diverse terrains. These establish advanced early warning systems, providing critical support climate-resilient management risk mitigation spatiotemporally predictions.

Online Prediction of Concrete Temperature During the Construction of an Arch Dam Based on a Sparrow Search Algorithm–Incremental Support Vector Regression Model

Applied Sciences, Год журнала: 2025, Номер 15(9), С. 5053 - 5053

Опубликована: Май 1, 2025

The accurate prediction of concrete temperature during arch dam construction is essential for crack prevention. internal the poured blocks influenced by dynamic factors such as material properties, age, heat dissipation conditions, and control measures, which are highly time-varying. Conventional models, rely on offline data training, struggle to capture these time-varying dynamics, resulting in insufficient accuracy. To overcome limitations, this study constructed a sparrow search algorithm–incremental support vector regression (SSA-ISVR) model online prediction. First, SSA was employed optimize penalty kernel coefficients ISVR algorithm, minimizing errors between predicted measured temperatures establish pretrained initial model. Second, untrained samples were dynamically monitored incorporated using Karush–Kuhn–Tucker (KKT) conditions identify unlearned information, prompting updates. Additionally, redundant removed based sample similarity error-driven criteria enhance training efficiency. Finally, model’s accuracy reliability validated through actual case studies compared LSTM, BP, models. results indicate that SSA-ISVR outperforms aforementioned effectively capturing changes accurately predicting variations, with mean absolute error 0.14 °C.
