  1. 11. A General Approach to Inaudible Adversarial Perturbations in a Black-box Setting

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

    Författare :Johan Sörell; [2021]
    Nyckelord :;

    Sammanfattning : Deep learning is currently being deployed in many speech recognition systems. While these systems can achieve state-of-the-art performance, they are known to be susceptible to adversarial perturbations. These are minor perturbations to the input data, crafted specifically to cause erroneous behavior from the system. LÄS MER

  3. 12. On the Topic of Unconstrained Black-Box Optimization with Application to Pre-Hospital Care in Sweden : Unconstrained Black-Box Optimization

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Tim Anthony; [2021]
    Nyckelord :Optimization; Non-convex optimization; Black-box optimization; Simulation study;

    Sammanfattning : In this thesis, the theory and application of black-box optimization methods are explored. More specifically, we looked at two families of algorithms, descent methods andresponse surface methods (closely related to trust region methods). LÄS MER

  4. 13. Self-Optimization of Camera Hardware

    Master-uppsats, Lunds universitet/Institutionen för datavetenskap

    Författare :Simon Kristoffersson Lind; Johannes Tykesson; [2021]
    Nyckelord :Optimization; Black-box optimization; Evolutionary; Bayesian; Simulated Annealing; DIRECT; Particle Swarm; Simplex; Technology and Engineering;

    Sammanfattning : This thesis aims to investigate the automatic tuning of hardware parameters in a camera's image processing pipeline. In order to solve the tuning problem, it is formulated as a black-box optimization problem centered around a physical camera unit. Optimization is performed by comparing the camera's output to a reference image. LÄS MER

  5. 14. Marketers are Watching You : An exploration of AI in relation to marketing, existential threats, and opportunities

    Kandidat-uppsats, Jönköping University

    Författare :Sofia Lindström; Sebastian Edemalm; Erik Reinholdsson; [2021]
    Nyckelord :Artificial Intelligence; AI; Marketing Automation; Machine Learning; Bubble; Bias; Personalization; Black Box; Manipulation; Marketing; Digital Marketing; Digitalization;

    Sammanfattning : Background: As of today, it is apparent that with the ever-changing demands and needs of customers, companies are facing enormous pressure to deliver the right value, on time, in the right way, and proper manner. To realize the full potential of Artificial Intelligence (AI), a careful plan and method need to be established in the development and deployment when incorporating the technology with marketing.

  7. 15. Bayesian Parameter Tuning of the Ant Colony Optimization Algorithm : Applied to the Asymmetric Traveling Salesman Problem

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

    Författare :Emmy Yin; Klas Wijk; [2021]
    Nyckelord :;

    Sammanfattning : The parameter settings are vital for meta-heuristics to be able to approximate the problems they are applied to. Good parameter settings are difficult to find as there are no general rules for finding them. Hence, they are often manually selected, which is seldom feasible and can give results far from optimal.
