Research ArticleOpen accessIn the keywordsA Comparison Study between Different Sampling Strategies for Intrusion Detection System of Active Learning ModelGhofran Mohammad Alqaralleh, Mohammad Aref Alshraideh, Ali AlrodanActive learning aims to train an accurate model with minimum cost by labeling the most informative instances without compromising the model performance. So, choosing an efficient criterion for instance selection is the most important step. Sampling stage is the main issue in active learning for many problems such as intrusion detection system. There are many methods for sampling stage to … …Journal of Computer Science, Vol. 14, Issue 8 · 26 Aug 2018 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractUncertainty-Aware Ensemble Models for Improved Defect Detection in Noisy DataMadhavi Perla, Gadi Lava Raju, A Radha Krishna et al.Software defect prediction plays a crucial role in ensuring software quality and reliability, especially as modern systems become more complex and data rich. This study introduces an uncertainty-aware ensemble learning framework aimed at improving defect classification performance in noisy and imbalanced datasets, particularly those from the PROMISE and NASA KC1 repositories. The proposed model integrates multiple classifiers in a multi-learner … …Journal of Computer Science, Vol. 22, Issue 4 · 27 Apr 2026 · 1,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOVID-19 and Cause-Seeking. An Exploratory Study in ItalyMaurizio Norcia, Elisa ColìIn 2020, over 2 million Italian people contracted the SARS-CoV-2 virus. A pandemic of this magnitude and the very stringent countermeasures that have been adopted had a disruptive effect on people's lives, at a psychological, social, and economic levels. The exploratory study illustrated in this article focuses on the search for causes carried out by people and prompted by the … …Journal of Social Sciences, Vol. 18, Issue 1 · 10 Jan 2023 · 5,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Adaptive Measures Among Smallholder Farmers in Akwa Ibom State, NigeriaObot Akaninyene, Obiekwe NgoziAgricultural production/activities in Nigeria depends on rainfall, which often occurs only at certain times of the year and thus makes agriculture very susceptible to crop failure, insect infestation which causes poor returns on agricultural produce for farmers . Adoption of climate change mitigating strategies is key to coping with variations in weather conditions and the achievement of increased agricultural production … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 19 Sep 2022 · 6,261 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of the Earth's Surface State by Unsupervised Classification: Case of Vegetated, Aquatic and Mineral SurfacesJean-Claude Okaingni, Sié Ouattara, Adles Kouassi, Alain ClémentIn this study, we propose an unsupervised classification scheme based on the Dempster-Shafer Theory (TDS) and the Dezert-Smarandache Theory (DSmT) to characterize vegetated, aquatic and mineral surfaces. From pre-processed ASTER satellite images (georeferencing, geometric correction and 15 m re-sampling), neo-channels were produced by determining the spectral indices NDVI, MNDWI and NDBaI, considered as sources of information for classification of a … …American Journal of Applied Sciences, Vol. 15, Issue 7 · 27 Aug 2018 · 8,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractSOFT COMPUTING APPROACH TO PREDICT INTRACRANIAL PRESSURE VALUESMario VersaciThe estimation and the prediction of the values related to the Intracranial Pression (ICP) represents an important step for the evaluation of the compliance of the human brain, above all in those cases in which the increase of the ICP values determines high risk conditions for the patient. The regular therapy is neuro-surgical but, waiting for it, it is needed … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 7 Mar 2014 · 6,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractTunnel Static Behavior Assessed by a Probabilistic Approach to the Back-AnalysisClaudio Oggeri, Pierpaolo OresteProblem statement: The steps of the validation procedure of the project of a tunnel are briefly illustrated in this study, starting from the geological and structural surveys on the excavation walls and the measurement of the physical and mechanical parameters during the excavation works. Unfortunately, however, the knowledge of the rock mass, which is fundamental to the project, is usually … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetention Pond Sediment Accumulation Prediction using Monte Carlo SimulationSupiah Shamsudin, Abd Rashid Mohd Darom, Irma Norazurah Mohamad, Azmi Ab RahmanProblem statement: A study in Malaysia had been carried out to predict the sediment accumulation in urban detention ponds. Suspended sediment is pollutant of primary concern to the river that results in adverse environmental effect. Detention pond becomes a practical approach to this problem. Suspended sediment that settled in stormwater detention pond, can bring effect to the detention pond functions. … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 30 Jan 2012 · 7,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Community Health Risks: Proactive Vs Reactive SamplingSarah Taylor, Chelsea Papadopoulos, Sarah Vieillet, Peter Di MarcoProblem statement: A considerable number of native birds died in the West Australian coastal town of Esperance and surroundings during late 2006 and early 2007, which raised community concerns about environmental contamination. Forensic investigations of dead birds suggested that lead may have been the causative agent. At the time, lead and nickel, as well as iron ore and other materials, … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 6,840 accessesView PDFCite
