  2. 2. Utilizing Diversity and Performance Measures for Ensemble Creation

    University dissertation from Örebro universitet

    Author : Tuve Löfström; Högskolan i Skövde.; Högskolan i Skövde.; Högskolan i Borås.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Teknik; Technology; Ensemble Learning; Machine Learning; Diversity; Artificial Neural Networks; Data Mining; Information Fusion; ensemble learning; machine learning; diversity; artificial neural networks; information fusion; Computer Science; data mining;

    Abstract : An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. READ MORE

  3. 3. Predictive Techniques and Methods for Decision Support in Situations with Poor Data Quality

    University dissertation from Örebro University

    Author : Rikard König; Högskolan i Skövde.; Högskolan i Skövde.; Högskolan i Borås.; [2009]

    Abstract : Today, decision support systems based on predictive modeling are becoming more common, since organizations often collect more data than decision makers can handle manually. Predictive models are used to find potentially valuable patterns in the data, or to predict the outcome of some event. READ MORE

  4. 4. Tensions and Contradictions in Information Management. An Activity-theoretical Approach to Information Activities in a Swedish Youth-Peace Organisation

    University dissertation from Göteborg : Göteborg University

  5. 5. Collaboration and Coordination Challenges in Patient-Centered Care Models and Informaion Services

    University dissertation from Stockholm : Department of Computer and Systems Sciences, Stockholm University

    Author : Monica Winge; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; patient-centered care; healthcare; social care; home care; collaboration; coordination; care processes; processes coordination; multi-sectoral collaboration; communication; information models; information services; management; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : This thesis reports on research focuses on how to deal with the fact that the organization and processesof today’s health and social care are becoming ever more complex as a consequence of societal trends, including an aging population and an increased reliance on care at home. The overall research goal is to suggest ways in which IT-based solutions can enable and leverage collaboration and coordination insituations where a co-morbid patient is subject to care delivered simultaneously by several different professionals and organizations.
