  1. 26. Implementation and verification of the Information Bottleneck interpretation of deep neural networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Feiyang Liu; [2018]
    Keywords : The Information bottleneck method; Mutual information; Deep neural networks; Binning; nformations askhack IB -metoden; ömsesidig information; djupa neuronnät; binning;

    Abstract : Although deep neural networks (DNNs) have made remarkable achievementsin various elds, there is still not a matching practical theory that is able toexplain DNNs' performances. Tishby (2015) proposed a new insight to analyzeDNN via the Information bottleneck (IB) method. READ MORE

  3. 27. Direct optimization of dose-volume histogram metrics in intensity modulated radiation therapy treatment planning

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Tianfang Zhang; [2018]
    Keywords : Optimization; intensity-modulated radiation therapy; DVH functions; dose-at-volume; volume-at-dose; value-at-risk; smooth approximation; kernel density estimation; fluence map optimization; Optimering; intensitetsmodulerad strålterapi; DVH-funktioner; dose-at-volume; volumeat- dose; value-at-risk; slätapproximation; ickeparametrisk skattning; fluensoptimering;

    Abstract : In optimization of intensity-modulated radiation therapy treatment plans, dose-volumehistogram (DVH) functions are often used as objective functions to minimize the violationof dose-volume criteria. Neither DVH functions nor dose-volume criteria, however,are ideal for gradient-based optimization as the former are not continuously differentiableand the latter are discontinuous functions of dose, apart from both beingnonconvex.

  4. 28. Hot Spot mapping - A spatial and methodological approach to analyzing outdoor crimes in Malmö.

    University essay from Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Author : Jimmy Holm; [2018]
    Keywords : Social Sciences;

    Abstract : This thesis aim to visualize and explore the methodological approach to finding the spatial patterning of crime through a geographical information system as a means for future guidance within spatial crime analysis. The analysis was applied to outdoor crimes for the city of Malmö in the year 2007. READ MORE

  5. 29. Online Outlier Detection in Financial Time Series

    University essay from KTH/Matematisk statistik

    Author : Robin Sedman; [2018]
    Keywords : ;

    Abstract : In this Master’s thesis, different models for outlier detection in financial time series are examined. The financial time series are price series such as index prices or asset prices. Outliers are, in this thesis, defined as extreme and false points, but this definition is also investigated and revised. READ MORE

  6. 30. Map change detection using GPS position data

    University essay from Lunds universitet/Matematik LTH

    Author : Lina Sjöstrand; Fanny Andersson; [2018]
    Keywords : autonomous driving; change detection; map inference; GPS; road network; HMM; Viterbi algorithm; OSM; map matching; crowd-sourced data; update maps; Technology and Engineering;

    Abstract : Technology advancement in autonomous driving is accelerating. For the technology to be safe it is crucial for the vehicles to have an updated map, meaning all vehicles should have a correct and identical representation of the current road network. READ MORE
