  1. 6. Förorenade områdens sårbarhet för klimatrelaterade naturolyckor

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Ulrika Westholm; [2018]
    Nyckelord :Contaminated sites; risk assessment; vulnerability; natural hazards; index; climate change.; Earth and Environmental Sciences;

    Sammanfattning : Throughout history industries have been located adjacent to water courses to use water in the process, for transport and release of wastewater. This is also the case along the Arboga river. LÄS MER

  3. 7. Content based filtering for application software

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Lindström; [2018]
    Nyckelord :Recommender system; content based filtering;

    Sammanfattning : In the study, two methods for recommending application software were implemented and evaluated based on their ability to recommend alternative applications with related functionality to the one that a user is currently browsing. One method was based on Term Frequency–Inverse Document Frequency (TF-IDF) and the other was based on Latent Semantic Indexing (LSI). LÄS MER

  4. 8. Distributionella representationer av ord för effektiv informationssökning : Algoritmer för sökning i kundsupportforum

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Tim Lachmann; Johan Sabel; [2017]
    Nyckelord :word2vec; fasttext; glove; LSI; LSA; word embeddings; information retrieval; search engine; machine learning; neural networks; natural language processing; NLP; distributional representations; word2vec; fasttext; glove; LSI; LSA; ordinbäddning; informationssökning; sökmotor; maskininlärning; språkteknologi; neurala nätverk; distributionella representationer;

    Sammanfattning : I takt med att informationsmängden ökar i samhället ställs högre krav på mer förfinade metoder för sökning och hantering av information. Att utvinna relevant data från företagsinterna system blir en mer komplex uppgift då större informationsmängder måste hanteras och mycket kommunikation förflyttas till digitala plattformar. LÄS MER

  5. 9. Effects of spatial resolution,land-cover heterogeneity and different classification methods on accuracy of land-cover mapping

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Tweneboa Kwame Awuah; [2017]
    Nyckelord :image classification; spectral unmixing; random forest RF ; feature extraction; spatial resolution; heterogeneity; support vector machine SVM ; endmember extraction;

    Sammanfattning : Despite improved spatial and spectral characteristics of satellite and aerial imaging systems, land-cover classification is still challenged by a continuously evolving and complex rural and urban landscape conditions resulting from diverse land-use scenarios. Sizes and material composition of impervious surfaces changes greatly from urban to rural areas, leading to varying spectral signatures and ultimately misclassification. LÄS MER
