  1. 1. Visual Bird's-Eye View Object Detection for Autonomous Driving

    University essay from Linköpings universitet/Datorseende

    Author : Erik Lidman; [2023]
    Keywords : computer vision; machine learning; neural networks; deep learning; autonomous driving; autonomous systems; datorseende; maskininlärning; neuronnät; djupinlärning; autonom körning; autonoma system;

    Abstract : In the field of autonomous driving a common scenario is to apply deep learningmodels on camera feeds to provide information about the surroundings. A recenttrend is for such vision-based methods to be centralized, in that they fuse imagesfrom all cameras in one big model for a single comprehensive output. READ MORE

  3. 2. Stochastic Frank-Wolfe Algorithm : Uniform Sampling Without Replacement

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Olof Håkman; [2023]
    Keywords : Stochastic Frank-Wolfe; Stochastic optimization; Sampling without replacement;

    Abstract : The Frank-Wolfe (FW) optimization algorithm, due to its projection free property, has gained popularity in recent years with typical application within the field of machine learning. In the stochastic setting, it is still relatively understudied in comparison to the more expensive projected method of Stochastic Gradient Descent (SGD). READ MORE

  4. 3. Hematologiska förändringar hos hund efter behandling med kliniska doser av prednisolon

    University essay from SLU/Dept. of Clinical Sciences

    Author : Linda Daly; [2020]
    Keywords : prednisolon; glukokortikoid; hematologiska förändringar; hund;

    Abstract : Glukokortikoider används frekvent inom veterinärmedicin tack vare sina antiinflammatoriska och immunsupprimerande egenskaper. Generella indikationer till behandling med glukokortikoider är bland annat allergier, immunmedierade sjukdomar, neoplastiska sjukdomar och som ersättningsterapi vid hypoadrenokortisism. READ MORE

  5. 4. Stratification, Sampling and Estimation: Finding the best design for the Swedish Investment Survey

    University essay from Statistiska institutionen

    Author : Linda Wiese; [2013]
    Keywords : sampling design; stratified simple random sampling without replacement STSRS ; probability proportional to size without replacement; Neyman allocation; Horvitz-Thompson estimation; generalised regression estimation GREG ; standard deviation; Swedish Investment Survey;

    Abstract : In this thesis, different methods are used to investigate the best design for the Swedish Investment Survey. The methods used today are stratify on number of employees, Neyman-allocation, STSRS-sampling and HT-estimation. The alternative methods in this thesis are stratify on turnover, -sampling and GREG-estimation. READ MORE

  6. 5. Implementation of a fast method for reconstruction of ISAR images

    University essay from Bildbehandling; Tekniska högskolan

    Author : Niklas Dahlbäck; [2003]
    Keywords : Technology; radar; RCS; radar cross section; ISAR; image reconstruction; algorithm; FFT; TEKNIKVETENSKAP;

    Abstract : By analyzing ISAR images, the characteristics of military platforms with respect to radar visibility can be evaluated. The method, which is based on the Discrete-Time Fourier Transform (DTFT), that is currently used to calculate the ISAR images requires large computations efforts. READ MORE
