  1. 21. Evaluating Feature Selection Methods for Automated Computer Based Diagnostics of Diabetes

    University essay from KTH/Datavetenskap

    Author : Erik Wachtmeister; Noel Karlsson Johansson; [2022]
    Keywords : ;

    Abstract : Diabetes affects roughly 8% of the world population over the age of 18 and causes approximately 5 million deaths for people over the age of 20 each year. Furthermore, maybe half of all people with diabetes are undiagnosed. They could be diagnosed with automated computer-based diagnostics, but machine learning has its challenges. READ MORE

  3. 22. Active Learning for Solving Expensive Optimization Problems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Siwei Fu; [2022]
    Keywords : ;

    Abstract : Many practical engineering and computer science problems can be translated into a global otimization problem where the task is to find the best (optimal) vector 𝒙𝒙∗ that gives the smallest possible function value 𝑓𝑓 = 𝑓𝑓(𝒙𝒙∗) for some function 𝑓𝑓() of interest. Often the function 𝑓𝑓() is expensive in the sense that it cannot be easily evaluated computationally or experimentally in terms of time and/or resources required. READ MORE

  4. 23. Explainable Artificial Intelligence for Radio Resource Management Systems : A diverse feature importance approach

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

    Author : Alexandru-Daniel Marcu; [2022]
    Keywords : Explainable artificial intelligence XAI ; Explainability pipeline; Feature importance; Kernel SHAP; CERTIFAI; Anchors; XAI in wireless systems; XAI for radio resource management; Förklarande artificiell intelligens XAI ; Förklarande pipeline; Prediktor betydelse; Kernel SHAP; CERTIFAI; Anchors; XAI i trådlösa system; XAI för radioresurshantering;

    Abstract : The field of wireless communications is arguably one of the most rapidly developing technological fields. Therefore, with each new advancement in this field, the complexity of wireless systems can grow significantly. READ MORE

  5. 24. The self-exciting Hawkes processand dynamic contagion

    University essay from Uppsala universitet/Sannolikhetsteori och kombinatorik

    Author : Isak Dahlqvist; [2022]
    Keywords : ;

    Abstract : We introduce the necessary theory to construct self-exciting processes, particularly random and Poisson measures. Our goal is to show how to work with and analyze self-exciting processes. We consider a Hawkes process with the exponential kernel, a counting process with an intensity that depends on the process itself. READ MORE

  6. 25. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays

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

    Author : Jesper Brunnström; [2021]
    Keywords : Active noise control; Secondary path modelling; Spatial; Adaptive filter; Multichannel; Least mean squares; Aktiv brusreducering; Sekundärvägsmodellering; Spatial; Adaptiv Filtrering; Multikanal; Minsta kvadratmetoden;

    Abstract : In this work we explore online secondary path modelling (SPM) in the context of spatial active noise control (ANC). Specifically, we are interested in the reduction of broadband noise over a three-dimensional region, without restrictions on microphone and loudspeaker array placement. READ MORE
