  1. 31. Regularization parameter selection methods for an inverse dispersion problem

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anna Palmberger; [2021]
    Keywords : ;

    Abstract : There are many regularization parameter selection methods that can be used when solving inverse problems, but it is not clear which one is best suited for the inverse dispersion problem. The suitability of three different methods for solving the inverse dispersion problem are evaluated here in order to pick a suitable method for these kinds of problems in the future. READ MORE

  3. 32. Data-Driven Methods for Sonar Imaging

    University essay from Linköpings universitet/Datorseende

    Author : Lovisa Nilsson; [2021]
    Keywords : Sonar; Reconstruction; Inverse Problems; Deep Learning; Data-driven Methods;

    Abstract : Reconstruction of sonar images is an inverse problem, which is normally solved with model-based methods. These methods may introduce undesired artifacts called angular and range leakage into the reconstruction. READ MORE

  4. 33. Overcoming Inter-carrier-interference in OFDM System

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Fukang Guo; Luoan Lu; [2021]
    Keywords : ICI; OFDM; TDCP; FDCE; Windowing-OFDM; 5G;

    Abstract : This master thesis aims for Inter-carrier interference (ICI) mitigation in orthogonal frequency division multiplexing (OFDM) system by considering designs of frequency domain cyclic extension(FDCE) and optimal windowing pulse shape. Although OFDM system has been put forward in the 1970s, it has just emerged in 4G. READ MORE

  5. 34. FPGA Implementation of an Anonymization Algorithm

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Niklas Kjellman; Rehenuma Tarannum; [2020]
    Keywords : FPGA anonymization privacy anonymization filter spacial filter; Technology and Engineering;

    Abstract : With the large amount of surveillance cameras in our public spaces there has been much discussion about their effects on privacy. Axis communications has an algorithm that tries to remedy this by making it hard to see who is in an image but still have it possible for a neural network to detect that there is a person present.

  6. 35. Scaling up Maximum Entropy Deep Inverse Reinforcement Learning with Transfer Learning

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

    Author : Emil Broqvist Widham; [2020]
    Keywords : ;

    Abstract : In this thesis an issue with common inverse reinforcement learning algorithms is identified, which causes them to be computationally heavy. A solution is proposed which attempts to address this issue and which can be built upon in the future. READ MORE
