  1. 1. Improved personalized suggestions on websites using machine learning

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

    Författare :Filiz Boyraz; [2020]
    Nyckelord :;

    Sammanfattning : Automated web personalization is a desired feature both for a website visitor and owner. The visitor is released from the burden of selecting settings or use search tools to adapt the website for their needs and find the right content. The owner benefits from having the visitors find content on the website they otherwise would have overlooked. LÄS MER

  3. 2. Attitude Navigation using a Sigma-Point Kalman Filter in an Error State Formulation

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Periklis-Konstantinos Diamantidis; [2017]
    Nyckelord :unscented Kalman filtering; information ltering; quaternions; attitude navigation; gyroscope modelling; error state formulation; sensor fusion;

    Sammanfattning : Kalman filtering is a well-established method for fusing sensor data in order to accuratelyestimate unknown variables. Recently, the unscented Kalman filter (UKF) has beenused due to its ability to propagate the first and second moments of the probability distribution of an estimated state through a non-linear transformation.

  4. 3. Use of Gravity Sensors for Free Space Orientation

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Victor Garcia-Fernández; [2015]
    Nyckelord :Kalman; Particle filter; Fixed-point math; MSP430; Kalman; Partikelfilter; fast punkt matematik; MSP430.; Kalman; filtro de partículas; álgebra de punto fijo; MSP430;

    Sammanfattning : This thesis deals with different approaches to filtering the signal output of a three axis accelerometerfor free space orientation, that is, finding the orientation of a sensor relative to gravity. Theplatform this orientation system is to be developed for is a low-power, high-efficiency fixed-pointmath microprocessor, therefore efficiency and mathematical operation precision are factors thatalso need to be taken into consideration in this work.

  5. 4. Evaluation of a Prototype for Relevance Profiling

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Karl-Johan Alm; [2013]
    Nyckelord :machine learning; twitter; information; grouping; social networks; relations;

    Sammanfattning : Only a small portion of the amounts of information generated online are relevant to a given person. In this thesis, a prototype for determining a relevance value based on sets of data for some topic is evaluated to determine its viability in a future product called Votia. LÄS MER

  7. 5. Distinguishing Visual Information from Visible Background Light Sources

    Kandidat-uppsats, KTH/Tillämpad fysik

    Författare :Axel Theorell; Anton Osika; [2013]
    Nyckelord :;

    Sammanfattning : This thesis regards problems of the form: Two light sources are present. The two sources have dierent light spectra. One of the sources carries information and the other source can be regarded as background light. LÄS MER
