Renewable energy plays an increasingly important role in our future. As fossil fuels become more difficult to extract and effectively process, renewables offer a solution the ever-increasing demands of world. However, shift toward renewable is not without challenges. While reliable means storage that can be converted into usable energy, are dependent on external factors used for generation. Efficient often relying batteries have limited number charge cycles. A robust efficient system forecasting power generation from sources help alleviate some difficulties associated with transition energy. Therefore, this study proposes attention-based recurrent neural network approach generated sources. To networks make accurate forecasts, decomposition techniques utilized applied time series, modified metaheuristic introduced optimized hyperparameter values networks. This has been tested two real-world datasets covering both solar wind farms. The models by metaheuristics were compared those produced other state-of-the-art optimizers terms standard regression metrics statistical analysis. Finally, best-performing model was interpreted using SHapley Additive exPlanations.

Maritime vessels provide a wealth of data concerning location, trajectories, and speed. However, while these are meticulously monitored logged to maintain course, they can also meta information. This work explored the potential data-driven techniques applied artificial intelligence (AI) tackle two challenges. First, vessel classification was through use extreme gradient boosting (XGboost). Second, trajectory time series forecasting tackled long-short-term memory (LSTM) networks. Finally, due strong dependence AI model performance on proper hyperparameter selection, boosted version well-known particle swarm optimization (PSO) algorithm introduced specifically for tuning hyperparameters models used in this study. The methodology real-world automatic identification system (AIS) both marine forecasting. Boosted PSO (BPSO) compared contemporary optimizers showed promising outcomes. XGBoost tuned using attained an overall accuracy 99.72% problem, LSTM mean square error (MSE) 0.000098 prediction challenge. A rigid statistical analysis performed validate outcomes, explainable principles were determined best-performing models, gain better understanding feature impacts decisions.

Polycyclic aromatic hydrocarbons (PAHs) refer to a group of several hundred compounds, among which 16 are identified as priority pollutants, due their adverse health effects, frequency occurrence, and potential for human exposure. This study is focused on benzo(a)pyrene, being considered an indicator exposure PAH carcinogenic mixture. For this purpose, we have applied the XGBoost model two-year database pollutant concentrations meteorological parameters, with aim identify factors were mostly associated observed benzo(a)pyrene describe types environments that supported interactions between other polluting species. The data collected at energy industry center in Serbia, vicinity coal mining areas power stations, where maximum concentration period reached 43.7 ngm-3. metaheuristics algorithm has been used optimize hyperparameters, results compared models tuned by eight cutting-edge algorithms. best-produced was later interpreted applying Shapley Additive exPlanations (SHAP). As indicated mean absolute SHAP values, temperature surface, arsenic, PM10, total nitrogen oxide (NOx) appear be major affecting its environmental fate.

Abstract: This work aims to test the performance of you only look once version 8 (YOLOv8) model for problem drone detection. Drones are very slightly regulated and standards need be established. With a robust system detecting drones possibilities regulating their usage becoming realistic. Five different sizes were tested determine best architecture size this problem. The results indicate high across all models that each is used specific case. Smaller suited lightweight approaches where some false identification tolerable, while largest with stationary systems require precision.

The vegetable sector is a vital pillar of society and an indispensable part the national economic structure. As significant segment agricultural market, accurately forecasting prices holds importance. Vegetable market pricing subject to myriad complex influences, resulting in nonlinear patterns that conventional time series methodologies often struggle decode. In this paper, we exploit average daily price data six distinct types vegetables sourced from seven key wholesale markets Beijing, spanning 2009 2023. Upon training LSTM model, discovered it exhibited exceptional performance on test dataset. Demonstrating robust predictive across various categories, model shows commendable generalization abilities. Moreover, has higher accuracy compared several machine learning methods, including CNN-based approaches. With R2 score 0.958 MAE 0.143, our registers enhancement over 5% forecast relative counterparts. Therefore, by predicting for upcoming week, envision application real-world settings aid growers, consumers, policymakers facilitating informed decision-making. insights derived research could augment transparency optimize supply chain management. Furthermore, contributes stability balance demand, offering valuable reference sustainable development industry.
