    [EN] Cloud computing instruction requires hands-on experience with a myriad of distributed computing services from a public cloud provider. Tracking the progress of the students, especially for online courses, requires one to automatically gather evidence and produce learning analytics in order to further determine the behavior and performance of students. With this aim, this paper describes the experience from an online course in cloud computing with Amazon Web Services on the creation of an open-source data processing tool to systematically obtain learning analytics related to the hands-on activities carried out throughout the course. These data, combined with the data obtained from the learning management system, have allowed the better characterization of the behavior of students in the course. Insights from a population of more than 420 online students through three academic years have been assessed, the dataset has been released for increased reproducibility. The results corroborate that course length has an impact on online students dropout. In addition, a gender analysis pointed out that there are no statistically significant differences in the final marks between genders, but women show an increased degree of commitment with the activities planned in the course.This research was funded by the Spanish "Ministerio de Economia, Industria y Competitividad through grant number TIN2016-79951-R (BigCLOE)", the "Vicerrectorado de Estudios, Calidad y Acreditacion" of the Universitat Politecnica de Valencia (UPV) to develop the PIME B29 and PIME/19-20/166, and by the Conselleria d'Innovacio, Universitat, Ciencia i Societat Digital for the project "CloudSTEM" with reference number AICO/2019/313.Moltó, G.; Naranjo-Delgado, DM.; Segrelles Quilis, JD.

    Density kernel depth for outlier detection in functional data

    Get PDF
    In this paper, we propose a novel approach to address the problem of functional outlier detection. Our method leverages a low-dimensional and stable representation of functions using Reproducing Kernel Hilbert Spaces (RKHS).We define a depth measure based on density kernels that satisfy desirable properties.We also address the challenges associated with estimating the density kernel depth. Throughout aMonte Carlo simulation we assess the performance of our functional depth measure in the outlier detection task under different scenarios. To illustrate the effectiveness of our method, we showcase the proposed method in action studying outliers in mortality rate curves.Este artículo se encuentra publicado en International Journal of Data Science and Analytics (Springer Nature)https://doi.org/10.1007/s41060-023-00420-

    Get PDF
    Big data is central to new developments in global clinical science aiming to improve the lives of patients. Technological advances have led to the routine use of structured electronic healthcare records with the potential to address key gaps in clinical evidence. The covid-19 pandemic has demonstrated the potential of big data and related analytics, but also important pitfalls. Verification, validation, and data privacy, as well as the social mandate to undertake research are key challenges. The European Society of Cardiology and the BigData@Heart consortium have brought together a range of international stakeholders, including patient representatives, clinicians, scientists, regulators, journal editors and industry. We propose the CODE-EHR Minimum Standards Framework as a means to improve the design of studies, enhance transparency and develop a roadmap towards more robust and effective utilisation of healthcare data for research purposes

    Using Image Transformations to Learn Network Structure

    Full text link
    Many learning tasks require observing a sequence of images and making a decision. In a transportation problem of designing and planning for shipping boxes between nodes, we show how to treat the network of nodes and the flows between them as images. These images have useful structural information that can be statistically summarized. Using image compression techniques, we reduce an image down to a set of numbers that contain interpretable geographic information that we call geographic signatures. Using geographic signatures, we learn network structure that can be utilized to recommend future network connectivity. We develop a Bayesian reinforcement algorithm that takes advantage of statistically summarized network information as priors and user-decisions to reinforce an agent's probabilistic decision.Comment: 11 pages, 6 figures, 5 tables, In Submission with International Journal of Data Science and Analytics, Special Issue: Domain Driven Data Minin

    A Visual Dashboard to Track Learning Analytics for Educational Cloud Computing

    Full text link
    [EN] Cloud providers such as Amazon Web Services (AWS) stand out as useful platforms to teach distributed computing concepts as well as the development of Cloud-native scalable application architectures on real-world infrastructures. Instructors can benefit from high-level tools to track the progress of students during their learning paths on the Cloud, and this information can be disclosed via educational dashboards for students to understand their progress through the practical activities. To this aim, this paper introduces CloudTrail-Tracker, an open-source platform to obtain enhanced usage analytics from a shared AWS account. The tool provides the instructor with a visual dashboard that depicts the aggregated usage of resources by all the students during a certain time frame and the specific use of AWS for a specific student. To facilitate self-regulation of students, the dashboard also depicts the percentage of progress for each lab session and the pending actions by the student. The dashboard has been integrated in four Cloud subjects that use different learning methodologies (from face-to-face to online learning) and the students positively highlight the usefulness of the tool for Cloud instruction in AWS. This automated procurement of evidences of student activity on the Cloud results in close to real-time learning analytics useful both for semi-automated assessment and student self-awareness of their own training progress.This research was funded by the Spanish Ministerio de Economia, Industria y Competitividad, grant number TIN2016-79951-R (BigCLOE) and by the Vicerrectorado de Estudios, Calidad y Acreditacion of the Universitat Politecnica de Valencia (UPV) to develop the PIME B29.Naranjo, DM.; Prieto, JR.; Moltó, G.; Calatrava Arroyo, A.

    Big data is important to new developments in global clinical science that aim to improve the lives of patients. Technological advances have led to the regular use of structured electronic health-care records with the potential to address key deficits in clinical evidence that could improve patient care. The COVID-19 pandemic has shown this potential in big data and related analytics but has also revealed important limitations. Data verification, data validation, data privacy, and a mandate from the public to conduct research are important challenges to effective use of routine health-care data. The European Society of Cardiology and the BigData@Heart consortium have brought together a range of international stakeholders, including representation from patients, clinicians, scientists, regulators, journal editors, and industry members. In this Review, we propose the CODE-EHR minimum standards framework to be used by researchers and clinicians to improve the design of studies and enhance transparency of study methods. The CODE-EHR framework aims to develop robust and effective utilisation of health-care data for research purposes

    Get PDF
    The Journal of Apicultural Research (JAR) is a peer-reviewed, scientific journal dedicated to examining and publishing the latest research on bees from around the world. JAR publishes many different types of articles to reach different international audiences, from career scientists to students and well-informed beekeepers. These comprise original, theoretical, and experimental research papers, as well as authoritative notes, comments, and reviews on scientific aspects of all types of bees (superfamily Apoidea). As of 2021, JAR has an Impact Factor of 2.407 and is ranked 33rd out of 100 in the Entomology category (© InCites Journal Citation Reports®, Clarivate Analytics, 2022). Five regular issues are published per year and special issues are added when timely topics arise, the latest being a special issue on stingless bees (2022) and review papers (2023). In the last decade, COLOSS BEEBOOK chapters are published in JAR. These open-access chapters are a collection of the Standard Methods used in honey bee research, including the study of parasites, pests, and hive products. They are a primary reference resource for bee researchers across the globe and facilitate new projects that might not otherwise be undertaken by laboratories that are new to apidology (236,516 downloads - Taylor & Francis 3,028 citations - Web of Science, 2022). The Journal of Apicultural Research was founded by the International Bee Research Association (IBRA) in 1962. The very first issue included a Note from the first Editors, Dr. Eva Crane & Dr. James Simpson, who introduced JAR as a new opportunity for publication: “The journal will cover all aspects of bees, Apis and non-Apis, and substances used or produced by them, their pollinating activities, and organisms causing diseases or injuries to them.” Since the first issue, this legacy has been maintained in more than 2,800 scientific articles, co-authored by some 1,900 researchers, published so far in JAR, making our journal a key forum for the international exchange of scientific data in apidology. We encourage colleagues from around the globe to continue to participate in sharing their research with the scientific community by publishing in JAR.info:eu-repo/semantics/publishedVersio
