  1. 1. Localization of Combat Aircraft at High Altitude using Visual Odometry

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jenny Nilsson Boij; [2022]
    Keywords : Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

    Abstract : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. READ MORE

  3. 2. Evaluating the effects of data augmentations for specific latent features : Using self-supervised learning

    University essay from KTH/Hälsoinformatik och logistik

    Author : Markus Ingemarsson; Jacob Henningsson; [2022]
    Keywords : Contrastive learning; data augmentations; deep learning; invariant features; machine learning; representation similarity analysis; self-supervised learning; SimCLR; Kontrast inlärning; datamodifieringar; djupinlärning; maskininlärning; SimCLR; självövervakat lärande; oföränderliga egenskaper; representativ likhetsanalys;

    Abstract : Supervised learning requires labeled data which is cumbersome to produce, making it costly and time-consuming. SimCLR is a self-supervising framework that uses data augmentations to learn without labels. This thesis investigates how well cropping and color distorting augmentations work for two datasets, MPI3D and Causal3DIdent. READ MORE

  4. 3. Invariant Propagation for Solvers of Constraint-Based Local Search Technology

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Samuel Bodin; [2022]
    Keywords : ;

    Abstract : Constraint-based local search is a technology for solving constrained optimisation problems and constraint satisfaction problems. Solvers of this kind rely on the notion of invariants and an invariant propagation algorithm during search. READ MORE

  5. 4. Topological Band Theory, An Overview

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Jens Roderus; [2021-06-14]
    Keywords : ;

    Abstract : Topological insulators, superconductors and semi-metals are states of ma er with unique features such as quantized macroscopic observables and robust, gapless edge states. ese states can not be explained by standard quantum mechanics, but require also the framework of topology to be properly characterized.

  6. 5. Shape Detection in Images Using Machine Learning

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Axel Devlin; [2021]
    Keywords : Multi-class classification; SVM; support vector machine; supervised learning; machine learning; Flerklass klassificering; SVM; stödvektormaskin; övervakat lärande; maskininlärning;

    Abstract : Rapporten undersöker hur man ska gå tillväga för att implementera en support vector machinesom kan klassificera olika former i bilder med hjälp av OpenCV libraryt i Python. Dettakommer att göras genom att beräkna scale-invariant features. De scale-invariant features somkommer undersökas är simple features och Hu moments. READ MORE
