  1. 16. Keystroke dynamics for student authentication in online examinations

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Rebecka Mattsson; [2020]
    Keywords : ;

    Abstract : Biometrics are distinctive for each person, and can not be given away or hacked like a password. Keystroke dynamics is a behavioral biometric characteristic that can be used as a complementary authentication step [1]. In online examinations it is difficult to make sure that each student write their own work. READ MORE

  3. 17. Capturing Tail Risk in a Risk Budgeting Model

    University essay from KTH/Matematisk statistik

    Author : Filip Lundin; Markus Wahlgren; [2020]
    Keywords : ;

    Abstract : Risk budgeting, in contrast to conventional portfolio management strategies, is all about distributing the risk between holdings in a portfolio. The risk in risk budgeting is traditionally measured in terms of volatility and a Gaussian distribution is commonly utilized for modeling return data. READ MORE

  4. 18. Particle-Based Online Bayesian Learning of Static Parameters with Application to Mixture Models

    University essay from KTH/Matematisk statistik

    Author : Rutger Fuglesang; [2020]
    Keywords : Statistics; applied mathematics; sequential monte carlo; SMC; Statistical inference; Statisk; sekventiell monte carlo; SMC; tillämpad matematik;

    Abstract : This thesis investigates the possibility of using Sequential Monte Carlo methods (SMC) to create an online algorithm to infer properties from a dataset, such as unknown model parameters. Statistical inference from data streams tends to be difficult, and this is particularly the case for parametric models, which will be the focus of this paper. READ MORE

    Abstract : The automotive industry is undertaking major technological steps in an effort to reduce emissions and fight climate change. To reduce the reliability on fossil fuels a lot of research is invested into electric motors (EM) and their applications. READ MORE

  6. 20. Applying Generative Adversarial Networks for the Generation of Adversarial Attacks Against Continuous Authentication

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

    Author : Zijian Fan; [2020]
    Keywords : ;

    Abstract : Cybersecurity has been a hot topic over the past decades with lots of approaches being proposed to secure our private information. One of the emerging approaches in security is continuous authentication, in which the computer system is authenticating the user by monitoring the user behavior during the login session. READ MORE
