  1. 21. Targeted Improvement of a Deep Learning Object Detector Using Synthetic Training Data

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Katja Palmkvist; Olivia Mattsson; [2022]
    Nyckelord :Machine Learning; Deep Learning; Object Detection; Computer Vision; Synthetic Data; 3D-rendering; Technology and Engineering;

    Sammanfattning : When working with object detection, the quality and quantity of the training data is often a recurrent bottleneck. This thesis proposes a technique of incrementally improving an object detector using synthetically rendered data. LÄS MER

  3. 22. Increased evasion resilience in modern PDF malware detectors : Using a more evasive training dataset

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

    Författare :Oscar Ekholm; [2022]
    Nyckelord :Malware Analysis; Malicious PDF; Malware Detection; Machine Learning; Evasion; Analys av skadlig programvara; Skadlig PDF; Detektion av skadlig programvara; Maskininlärning; Undanflykt;

    Sammanfattning : The large scale usage of the PDF coupled with its versatility has made the format an attractive target for carrying and deploying malware. Traditional antivirus software struggles against new malware and PDF's vast obfuscation options. In the search of better detection systems, machine learning based detectors have been developed.

  5. 24. Characterization of Coliform Bacteria in Drinking Water Treatment Plant

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Oskar Westöö; [2021]
    Nyckelord :Coliform bacteria; Coliform detection; Coliform characterization; PCR; Drinking water treatment.;

    Sammanfattning : Termen koliforma bakterier beskriver en grupp indikatororganismer som används för att bedöma renligheten och integriteten hos reningsverk samt distributionssystem som nyttjas vid dricksvattenproduktion. För närvarande ställer styrande förvaltningsmyndigheter endast krav på detektion av antalet koliforma bakterier i dricksvatten via odlingsbaserade metoder. LÄS MER

  7. 25. Convolutional neural network based object detection in a fish ladder : Positional and class imbalance problems using YOLOv3

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

    Författare :Patrik Ekman; [2021]
    Nyckelord :Object detection; Computer vision; Fish ladder; Imbalance problems; Imbalanced data; YOLO; Convolutional Neural Network; Deep learning; Objektdetektering; Datorseende; Fisktrappa; Obalanser; Obalanserad data; YOLO; Convolutional Neural Network; Djupinl¨arning;

    Sammanfattning : Hydropower plants create blockages in fish migration routes. Fish ladders can serve as alternative routes but are complex to install and follow up to help adapt and develop them further. In this study, computer vision tools are considered in this regard. LÄS MER
