The convergence analysis of the tracking error system is conducted to affirm that the proposed control algorithm can achieve the formation tracking when the switching directed topologies have a directed spanning tree across each switching time interval.”

    Findings on Machine Learning Reported by Investigators at Indian Institute of Technology (High Resolution Landslide Susceptibility Mapping Using Ensemble Machine Learning and Geospatial Big Data)

    62-63页
    查看更多>>摘要:Data detailed on Machine Learning have been presented. According to news reporting originating in New Delhi, India, by NewsRx journalists, research stated, “Landslide susceptibility represents the potential of slope failure for given geo-environmental conditions. The existing landslide susceptibility maps suffer from several limitations, such as being based on limited data, heuristic methodologies, low spatial resolution, and small areas of interest.” Funders for this research include ISRO Space Applications Center, DST IC-IMPACTS, IIT Delhi IoE. The news reporters obtained a quote from the research from the Indian Institute of Technology, “In this study, we overcome all these limitations by developing a probabilistic framework that combines imbalance handling and ensemble machine learning for landslide susceptibility mapping. We employ a combination of One -Sided Selection and Support Vector Machine Synthetic Minority Oversampling Technique (SVMSMOTE) to eliminate class imbalance and develop smaller representative data from big data for model training. A blending ensemble approach using hyperparameter tuned Artificial Neural Networks, Random Forests, and Support Vector Machine, is employed to reduce the uncertainty associated with a single model. The methodology provides the landslide susceptibility probability and a landslide susceptibility class. A thorough evaluation of the framework is performed using receiver operating characteristic curves, confusion matrices, and the derivatives of confusion matrices. This framework is used to develop India’s first national-scale machine learning based landslide susceptibility map. The landslide database is carefully curated from global and local inventories, and the landslide conditioning factors are selected from a multitude of geophysical and climatological variables. The Indian Landslide Susceptibility Map (ILSM) is developed at a resolution of 0.001 degrees (similar to 100 m) and is classified into five classes: very low, low, medium, high, and very high. We report an accuracy of 95.73 %, sensitivity of 97.08 %, and matthews correlation coefficient (MCC) of 0.915 on test data, demonstrating the accuracy, robustness, and generalizability of the framework for landslide identification. The model classified 4.75 % area in India as very highly susceptible to landslides and detected new landslide susceptible zones in the Eastern Ghats, hitherto unreported in the government landslide records.”

This paper aims to enrich the scientific community’s database on structural dynamics and experimental methodologies pertinent to system modelling. Leveraging experimental measurements obtained from mass-reinforced beams, these datasets validate numerical models, refine identification techniques, quantify uncertainties, and continuously foster machine learning algorithms’ evolution to monitor structural integrity. Furthermore, the beam dataset is data-driven and can be used to develop and test innovative structural health monitoring strategies, specifically identifying damages and anomalies within intricate structural frameworks. Supplemental datasets like Mass-position and damage index introduce parametric uncertainty into experimental and damage identification metrics. Thereby offering valuable insights to elevate the efficacy of monitoring and control techniques.”

    University of Naples Federico Ⅱ Reports Findings in Machine Learning (Evaluation of different machine learning algorithms for predicting the length of stay in the emergency departments: a single-centre study)

    64-64页
    查看更多>>摘要:New research on Machine Learning is the subject of a report. According to news reporting originating in Naples, Italy, by NewsRx journalists, research stated, “Recently, crowding in emergency departments (EDs) has become a recognised critical factor impacting global public healthcare, resulting from both the rising supply/demand mismatch in medical services and the paucity of hospital beds available in inpatients units and EDs. The length of stay in the ED (ED-LOS) has been found to be a significant indicator of ED bottlenecks.” The news reporters obtained a quote from the research from the University of Naples Federico Ⅱ, “The time a patient spends in the ED is quantified by measuring the ED-LOS, which can be influenced by inefficient care processes and results in increased mortality and health expenditure. Therefore, it is critical to understand the major factors influencing the ED-LOS through forecasting tools enabling early improvements. The purpose of this work is to use a limited set of features impacting ED-LOS, both related to patient characteristics and to ED workflow, to predict it. Different factors were chosen (age, gender, triage level, time of admission, arrival mode) and analysed. Then, machine learning (ML) algorithms were employed to foresee ED-LOS. ML procedures were implemented taking into consideration a dataset of patients obtained from the ED database of the ‘San Giovanni di Dio e Ruggi d’Aragona’ University Hospital (Salerno, Italy) from the period 2014-2019. For the years considered, 496,172 admissions were evaluated and 143,641 of them (28.9%) revealed a prolonged ED-LOS. Considering the complete data (48.1% female vs. 51.9% male), 51.7% patients with prolonged ED-LOS were male and 47.3% were female. Regarding the age groups, the patients that were most affected by prolonged ED-LOS were over 64 years. The evaluation metrics of Random Forest algorithm proved to be the best; indeed, it achieved the highest accuracy (74.8%), precision (72.8%), and recall (74.8%) in predicting ED-LOS. Different variables, referring to patients’ personal and clinical attributes and to the ED process, have a direct impact on the value of ED-LOS.”

    查看更多>>摘要:Investigators discuss new findings in artificial intelligence. According to news reporting originating from Casablanca, Morocco, by NewsRx correspondents, research stated, “With the rapid advancements and notable achievements across various application domains, Machine Learning (ML) has become a vital element within the Internet of Things (IoT) ecosystem.” Our news correspondents obtained a quote from the research from Hassan Ⅱ University: “Among these use cases is IoT security, where numerous systems are deployed to identify or thwart attacks, including intrusion detection systems (IDSs), malware detection systems (MDSs), and device identification systems (DISs). Machine Learning-based (ML-based) IoT security systems can fulfill several security objectives, including detecting attacks, authenticating users before they gain access to the system, and categorizing suspicious activities. Nevertheless, ML faces numerous challenges, such as those resulting from the emergence of adversarial attacks crafted to mislead classifiers. This paper provides a comprehensive review of the body of knowledge about adversarial attacks and defense mechanisms, with a particular focus on three prominent IoT security systems: IDSs, MDSs, and DISs. The paper starts by establishing a taxonomy of adversarial attacks within the context of IoT. Then, various methodologies employed in the generation of adversarial attacks are described and classified within a two-dimensional framework.”

    Researcher from Chongqing University of Posts and Telecommunications Discusses Findings in Machine Learning (Extracting Shrubland in Deserts from Medium-Resolution Remote-Sensing Data at Large Scale)

    66-67页
    查看更多>>摘要:Investigators publish new report on artificial intelligence. According to news originating from Chongqing, People’s Republic of China, by NewsRx editors, the research stated, “Shrubs are important ecological barriers in desert regions and an important component of global carbon estimation.” Financial supporters for this research include National Key Research And Development Program of China; Science And Technology Fundamental Resources Investigation Program. Our news correspondents obtained a quote from the research from Chongqing University of Posts and Telecommunications: “However, the shrubland in deserts has been hardly presented, although many high-quality land cover datasets with a 10 m scale based on remote-sensing data have been publicly released products. Therefore, the underestimation of carbon storage is inevitable with the absence of desert shrublands. The existing land-cover datasets have been analyzed and compared, and it has been found that the reason for missing the shrubland in deserts is mainly indued by the absence of shrubland samples, which are easy to neglect and difficult to retrieve. In this study, we developed a semi-automatic method to extract shrubland samples in deserts as the updated input for the machine-learning method. Firstly, the initial samples of desert shrublands were identified from the very high spatial-resolution (0.3 0.5 m) imagery on GEE, and the maximum NDVI from Sentinel-2 was used for double-checking. Secondly, a feature-based method was used to learn the feature from the initial samples and a similarity-based searching method was employed to automatically expand the samples.”

    Tongji University Reports Findings in Personalized Medicine (Development and validation of a pathomics model for predicting CXCL8 expression and prognosis with machine learning in head and neck cancer)

    67-68页
    查看更多>>摘要:New research on Drugs and Therapies - Personalized Medicine is the subject of a report. According to news reporting originating in Shanghai, People’s Republic of China, by NewsRx journalists, research stated, “It is imperative to investigate a method to indicate prognosis and to seek new biological markers for personalized medicine for head and neck squamous cell carcinoma (HNSCC) patients. Pathomics based on quantitative medical imaging analysis has emerged lately.” The news reporters obtained a quote from the research from Tongji University, “CXCL8, a crucial inflammatory cytokine, is reflected in overall survival (OS). This study aimed to explore associations of the CXCL8 mRNA expression with pathom ics features and investigate the underlying biology of CXCL8. Clinical information and TPM(transcripts per million) mRNA sequencing data were obtained from the TCGA TCGA- HNSCC data set. The correlation between CXCL8 mRNA expression and patients’ survival rate was identified using the Kaplan Kaplan-Meier survival curve. We retrospectively analyzed 313 samples diagnosed with HNSCC in the TCGA database. Pathomics features were extracted from HE images, then using mRMR_RFE method and screened by the Logistic Regression(LR) algorithm. According to Kaplan Kaplan-Meier curves, the high expression of CXCL8 had a significant association with OS deterioration. The LR pathomics model integrated 16 radiomics features identified by the mRMR_RFE method in the training set and performed well in the testing set. The calibration plots revealed that the high gene expression probability predicted by the pathomics model had a decent agreement with actual observation. And the model has high clinical practicability. The pathomics model reflected by CXCL8 mRNA expression is an effective tool for predicting the prognosis in HNSCC patients and can assist clinical decisiondecisionmaking.”
