    CASH: Confidence-Calibrated Deep Feature Crossing for Classification-Aware Heterogeneous Task Scheduling

    Chuanlin Jian1, Yuanchen Sun2, Xiangcheng Liu1, Xuming Huang3, Samaneh Beheshti Kashi4, Xing Hu1,*

    CMC-Computers, Materials & Continua, Vol.89, No.2, 2026, DOI:10.32604/cmc.2026.086441 - 15 September 2026

    Abstract Heterogeneous clusters now carry most artificial-intelligence, scientific-computing, cloud, and edge-assisted workloads, yet scheduling them well remains difficult: workload semantics, hardware capability, queue state, and energy behavior are tightly coupled. Existing schedulers, whether heuristic, learning-based, or built on reinforcement learning, tend to rely on coarse resource requests, overlook the compatibility between task types and node classes, or carry a heavy training and deployment cost. This paper presents Classification-Aware Scheduling for Heterogeneous clusters (CASH), a confidence-calibrated, classification-aware scheduling framework that integrates workload profiling, deep feature crossing, gradient-boosted boundary modeling, and risk-aware heterogeneous resource mapping. CASH constructs a… More >

    S. M. Nihal Ahmed*, Afrim Hossen Khan, Md. Mazbaur Rashid

    Journal of Cyber Security, Vol.8, pp. 667-703, 2026, DOI:10.32604/jcs.2026.089357 - 14 September 2026

    Abstract Phishing remains one of the most persistent attack vectors in cybersecurity, and the gradient-boosting models that now dominate its automated detection are frequently deployed as opaque classifiers, which limits analyst trust and slows incident response. This paper presents a cross-dataset, explainability-driven evaluation of three gradient boosting algorithms–XGBoost, LightGBM, and CatBoost—for phishing URL classification, paired with a SHAP (Shapley Additive Explanations)-based framework that attributes every prediction to specific, human-readable features rather than treating the classifier as a black box. To eliminate a data leakage risk present in an earlier evaluation protocol—in which hyperparameter tuning and final… More >

    Short-Term Solar Radiation Forecasting System for Jiangsu Province Based on FY-4A Multispectral Data-Regional Applicability Validation for High-Penetration Photovoltaic Grid Integration

    Yunlong Du1, Shuyi Zhuang2,*, Zhigang Ye2, Qiangsheng Bu2, Yun Chai1, Yuanbing Wang3

    Energy Engineering, Vol.123, No.10, 2026, DOI:10.32604/ee.2025.074702 - 30 August 2026

    Abstract Under the dual challenges of global warming and energy transition, improving the short-term forecasting accuracy of surface solar radiation is of great practical importance for photovoltaic (PV) power integration. In this study, a short-term solar radiation forecasting model based on the XGBoost machine learning algorithm was developed for Jiangsu Province by integrating multispectral data from the Fengyun-4A (FY-4A) geostationary satellite with ground-based meteorological observations. The model incorporated 18 input features—including satellite reflectance, solar zenith angle, normalized difference vegetation index (NDVI), elevation, and land-cover data—to dynamically predict ground horizontal irradiance (GHI) with 0–4 h lead times.… More >

    Strength Prediction of Ultra-High Performance Concrete (UHPC) Based on BOHB-XGBOOST Algorithm

    Ling Wang1,2, Mohammad Faizuddin Md Noor2,*, Yanan Zhang3,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.2, 2026, DOI:10.32604/cmes.2026.084489 - 28 August 2026

    Abstract Ultra-high-performance concrete (UHPC) relies on multivariable mix design and curing regimes, which makes empirical estimation of compressive strength increasingly unreliable when material systems vary. In this context, unlike previous studies that only applied standard eXtreme Gradient Boosting (XGBoost), this study introduces an advanced hybrid optimization strategy, Bayesian Optimization and Hyperband (BOHB), which combines the sample efficiency of Bayesian optimization with the resource allocation mechanism of Hyperband, and incorporates SHapley Additive exPlanations (SHAP) for influencing factor analysis, thereby proposing a BOHB-XGBoost framework integrated with SHAP analysis. The proposed model demonstrates excellent predictive accuracy and stability, achieving… More >

    DDoS Defense Model on 5G Network Slices

    Kun-Lin Tsai1, Shih-Ting Chiu2, Chihhsiong Shih2, Fang-Yie Leu2,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.2, 2026, DOI:10.32604/cmes.2026.083958 - 28 August 2026

    Abstract With the quick development of 5G networks, network slicing and Open Radio Access Network (O-RAN) have become key technologies for improving network resource-allocation efficiency and flexibility. However, network slicing also faces intrusion-detection challenges, particularly for detecting DDoS attacks, which are difficult to detect due to traffic being silently transmitted across multiple sub-slices. To address this problem, this paper proposes a 5G network slicing intrusion detection mechanism, called the DDoS Defense Model on 5G Network Slices (2D5NS) which integrates machine learning and real-time traffic monitoring techniques to detect and mitigate DDoS attacks within an O-RAN.

    Study on Prediction of Grouting Material Curing Age Based on SAFT and Hyperparameter-Optimized XGBoost

    Pengcheng Xia1, Zhihong Pan1,*, Ruoyu Chen1, Linyuan Wang2

    Structural Durability & Health Monitoring, Vol.20, No.5, 2026, DOI:10.32604/sdhm.2026.080742 - 24 August 2026

    Abstract The grouting sleeves in prefabricated structures critically depend on the strength development of the grout; however, existing non-destructive testing methods struggle to capture its time-dependent evolution. This study proposes a hybrid prediction framework that combines the Synthetic Aperture Focusing Technique (SAFT) with a hyperparameter-optimized XGBoost model. Ultrasonic signals were collected at five curing stages (0, 1, 3, 7, and 28 days), from which SAFT-derived features and the area ratios of six color regions were extracted as input variables, with the curing age serving as the model output. Following a correlation analysis with compressive strength, three… More >

    Novel Sine-Lucas Oscillation Particle Swarm Optimization XGBoost Method for Landslide Prediction

    Qisen Jin1,2, Xiaoping Wang1, Feng Zhang2, Yu Zeng2, Jia Guo3,4,5,*, Jiacheng Li6,*

    CMC-Computers, Materials & Continua, Vol.89, No.1, 2026, DOI:10.32604/cmc.2026.080077 - 13 August 2026

    Abstract This paper presents a Sine-Lucas Oscillation Particle Swarm Optimization (SLOPSO) XGBoost algorithm for landslide susceptibility prediction. SLOPSO extends canonical PSO by introducing an oscillation factor constructed from a sine function and the Lucas number sequence into the position update, which raises swarm diversity and improves the global search. SLOPSO is then applied to tune six XGBoost hyperparameters using K-fold cross-validation accuracy as the fitness function. In experimental evaluation, SLOPSO-XGBoost reaches a mean test Accuracy of 0.8113, F1 of 0.8182, and AUC of 0.8856 over 10 independent runs, outperforming standard PSO-XGBoost and the default Random Forest, More >

    Mubariz Khan1, Hafeez Ur Rehman Siddiqui2, Adil Ali Saleem2, Muhammad Amjad Raza2,3, Lázaro Javier Hernández Rodríguez4,5,6,7, Pablo Herrero García4,8,9, Isabel de la Torre Díez10,*

    CMC-Computers, Materials & Continua, Vol.88, No.3, 2026, DOI:10.32604/cmc.2026.084269 - 23 July 2026

    Abstract Accurate forecasting of cryptocurrency prices remains an open challenge because classical statistical models cannot capture the non-linear, sentiment-driven dynamics of these markets. This study compares three hybrid deep learning architectures—VAR-LSTM, XGBoost-LSTM, and CNN-LSTM—to determine which best forecasts Bitcoin (BTC), Ethereum (ETH), and Dogecoin (DOGE) closing prices, and to quantify the marginal predictive value of Twitter sentiment integration. Six years of hourly OHLCV data (2017–2023) are augmented with VADER-scored Twitter sentiment polarity. Each model is formulated mathematically, implemented with documented hyperparameters (epochs, dropout, units;), and trained for one-step-ahead next-hour price prediction. Performance is measured by RMSE,… More >

    Abdulaziz A. Alsulami1, Qasem Abu Al-Haija2,*, Rayed Alakhtar3, Ahmad J. Tayeb3, Badraddin Alturki3, Huda Alsobhi4, Rayan A. Alsemmeari3

    CMC-Computers, Materials & Continua, Vol.88, No.3, 2026, DOI:10.32604/cmc.2026.083321 - 23 July 2026

    Abstract The rapid growth of the Internet of Things (IoT) devices has increased the attack area of modern networks, which makes effective intrusion detection systems (IDSs) essential to detect attacks that target IoT infrastructures. Federated learning is a promising approach for collaborative model training in the absence of centralized raw data. Conventional federated approaches rely on fixed client participation and static training configurations, which ensure symmetric treatment of clients despite heterogeneous local data distributions. This can limit convergence and degrade detection performance in non-IID conditions. This paper proposes an Adaptive Action-Based Federated Learning (AA-FL) framework for… More >
