Abstract Salinity intrusion stands out as a severe yet escalating challenge facing the water resource management and agricultural production of Mekong Delta in Vietnam result climate change upstream hydrological changes. This paper assesses efficacy six different machine learning (ML) deep models (DL) for hourly prediction salinity at four stations (Cau Quan, Tra Vinh, Ben Trai, Tran De). The are XGB, GB, SVR, LSTM, RNN ANN. Using data 2015–2020 with discharge tidal levels major inputs we designed training testing (training: Jan 2015-mid 2018; testing: mid 2018-Feb 2020). Our results prove that LSTM XGB have best prediction. In particular, they showed good accuracy predicting (RMSE: 0.25 to 0.30, R2 > 0.97) downstream 1.5 1.6, 0.88). success is due capacity high temporal resolution well spatio-temporal dynamics variation. structure has proven be effective capturing long-term dependencies, such seasonal patterns, while successfully non-linear interactions between greatest success, particularly discharge-tidal level interactions. ML/DL capable forecasting which can open doors data-driven Delta. Future studies should further add hydro-meteorological parameters, other hybrid architectures, real-time systems, could useful operationally wider applicability.

Background: A machine learning prognostic mortality scoring system was developed to address challenges in patient selection for clinical trials within the Intensive Care Unit (ICU) environment. The algorithm incorporates Red blood cell Distribution Width (RDW) data and other demographic characteristics predict ICU alongside existing systems like Simplified Acute Physiology Score (SAPS). Methods: algorithm, defined as a Mixed-effects logistic Random Forest binary (MixRFb), integrates (RF) classification with mixed-effects model outcomes, accounting repeated measurement data. Performance comparisons were conducted RF proposed MixRFb algorithms based solely on SAPS scoring, additional evaluation using descriptive receiver operating characteristic curve incorporating RDW’s predictive ability. Results: MixRFb, RDW covariates, outperforms SAPS-based variant, achieving an area under of 0.882 compared 0.814. Age identified most significant predictors mortality, reported by variable importance plot analysis. Conclusions: demonstrates superior efficacy predicting in-hospital identifies age primary predictors. Implementation this could facilitate trials, thereby improving trial outcomes strengthening ethical standards. Future research should focus enriching robustness, expanding its applicability across diverse settings demographics, integrating markers improve capabilities.

Unmanned Aerial Vehicles (UAVs) are increasingly employed across various domains, including communication, military, and delivery operations. Their reliance on the Global Positioning System (GPS) renders them vulnerable to GPS spoofing attacks, in which adversaries transmit false signals manipulate UAVs’ navigation, potentially leading severe security risks. This paper presents an enhanced integration of Long Short-Term Memory (LSTM) networks with a Genetic Algorithm (GA) for detection. Although GA–neural network combinations have existed decades, our method expands GA’s search space optimize wider range hyperparameters, thereby improving adaptability dynamic operational scenarios. The framework is evaluated using real-world dataset that includes authentic malicious under multiple attack conditions. While we discuss strategies mitigating CPU resource demands computational overhead, acknowledge direct measurements energy consumption or inference latency not included present work. Experimental results show proposed LSTM–GA approach achieved notable increase classification accuracy (from 88.42% 93.12%) F1 score 87.63% 93.39%). These findings highlight system’s potential strengthen UAV against provided hardware constraints other limitations carefully managed real deployments.

This study investigates the forecasting of Deutscher Aktienindex (DAX) market index by addressing nonlinear and nonstationary nature financial time series data using CEEMDAN decomposition method. The technique is used to decompose into intrinsic mode functions (IMFs) residuals, which are classified low‐frequency (LF), medium‐frequency (MF), high‐frequency (HF) components. Long short‐term memory (LSTM) networks applied MF HF components, while backpropagation neural network (BPNN) utilized for LF resulting in a robust hybrid model termed CEEMDAN‐LSTM‐BPNN. To evaluate performance proposed model, we compare it against several benchmark models, including ARIMA, RNN, LSTM, GRU, BIGRU, BILSTM, BPNN, CEEMDAN‐LSTM, CEEMDAN‐GRU, CEEMDAN‐BPNN, CEEMDAN‐GRU‐BPNN, across different training–testing splits (70% training/30% testing, 80% training/20% 90% training/10% testing). model’s predictive accuracy measured six metrics: root mean squared error (RMSE), absolute (MAE), percentage (MAPE), symmetric (SMAPE), logarithmic (RMSLE), R ‐squared. further assess performance, conduct Diebold–Mariano (DM) test forecast between models confidence set (MCS) statistical significance improvement. results demonstrate that CEEMDAN‐LSTM‐BPNN significantly outperforms other methods terms accuracy, with DM MCS tests confirming superiority multiple evaluation metrics. findings highlight importance combining advanced deep learning forecasting. research contributes development more accurate techniques, offering valuable implications decision‐making risk management.
