  1. 21. Utilizing Diversity and Performance Measures for Ensemble Creation

    Författare :Tuve Löfström; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ensemble Learning; Machine Learning; Diversity; Artificial Neural Networks; Data Mining; Information Fusion; Computer science; Datavetenskap; Teknik; Technology;

    Sammanfattning : 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. LÄS MER

  3. 22. Coding for the Wiretap Channel

    Författare :Mattias Andersson; Mikael Skoglund; Michael Lentmaier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : We consider code design for Wyner’s wiretap channel. Optimal coding schemes for this channel require an overall code that is capacity achieving for the main channel, partitioned into smaller subcodes, all of which are capacity achieving for the wiretapper’s channel. LÄS MER

  4. 23. Improving diagnosis of acute coronary syndromes in an emergency setting: A machine learning approach

    Författare :Michael Green; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ensemble; artificial neural network; machine learning; acute coronary syndrome; electrocardiogram; case based explanation; decision support system;

    Sammanfattning : Acute coronary syndrome (ACS) is the biggest people killer in the western world today. Despite well trained physicians and reliable diagnostic tools, diagnosing ACS early in the emergency departments (ED) remains a challenge. LÄS MER

  5. 24. Biomechanical methods and error analysis related to chronic musculoskeletal pain

    Författare :Fredrik Öhberg; Mats Djupsjöbacka; Åke Öberg; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical spine; ensemble theory; error analysis; helical axis; kinematics; movement analysis; neural coding; pattern recognition; spike sorting; whiplash; Medical technology; Medicinsk teknik;

    Sammanfattning : Background Spinal pain is one of humanity’s most frequent complaints with high costs for the individual and society, and is commonly related to spinal disorders. There are many origins behind these disorders e.g., trauma, disc hernia or of other organic origins. LÄS MER

  7. 25. Music and media in local life : Music practice in a Newar neighbourhood in Nepal

    Författare :Ingemar Grandin; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The study concerns the medialization of local music practice, where music practice is taken to mean in what ways music resources- repertoires, instruments, ensembles, and so on-are used in performance and listening, and medialization the permeation by media and their contentsof life at large.The study is based upon 16 months' ethnomusicological fieldwork in the Kathmandu Valley, Nepal, in 1985-86, 1987 and 1988.
