    Sammanfattning : In this work, the interference sensitivity of an FMCW radar has been evaluated by studying the impact on a simulated detection chain. A commercially available FMCW radar was first characterized and its properties then laid the foundation for a simulation model implemented in Matlab. LÄS MER

  7. 5. Detection of deceptive reviews : using classification and natural language processing features

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Johan Fernquist; [2016]
    Nyckelord :Machine learning; deceptive detection; SVM; support vector machines; natural language processing; NLP; classification;

    Sammanfattning : With the great growth of open forums online where anyone can givetheir opinion on everything, the Internet has become a place wherepeople are trying to mislead others. By assuming that there is acorrelation between a deceptive text's purpose and the way to writethe text, our goal with this thesis was to develop a model fordetecting these fake texts by taking advantage of this correlation.
