1. 1. Application of Machine Learning Algorithms for Post Processing of Reference Sensors

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :VASILIKI LAMPROUSI; [2021-04-01]
   Nyckelord :Object detection; machine learning; camera; sensors; semi-supervised learning;

   Sammanfattning : The Autonomous Drive (AD) systems and Advanced Driver Assistance Systems(ADAS) in the current and future generations of vehicles include a large numberof sensors which are used to perceive the vehicle’s surroundings. The productionsensors of these vehicles are verified and validated against reference data that areoriginated from high-accurate reference sensors that are placed in a reference roofbox at the top of the vehicle.

3. 2. Option Modelling by Deep Learning

   Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

   Författare :Niclas Klausson; Victor Tisell; [2021-02-10]
   Nyckelord :Deep learning; deep hedging; generative adversial networks; arbitrage pricing;

   Sammanfattning : In this thesis we aim to provide a fully data driven approach for modelling financial derivatives, exclusively using deep learning. In order for a derivatives model to be plausible, it should adhere to the principle of no-arbitrage which has profound consequences on both pricing and risk management. LÄS MER

4. 3. Deep Learning with Importance Sampling for Brain Tumor MR Segmentation

   Master-uppsats, KTH/Optimeringslära och systemteori

   Författare :Hanna Westermark; [2021]
   Nyckelord :Deep learning; importance sampling; segmentation; convolutional neural networks; MRI; brain tumour; Djupinlärning; importance sampling; segmentering; faltningsnätverk; MRI; hjärntumör;

   Sammanfattning : Segmentation of magnetic resonance images is an important part of planning radiotherapy treat-ments for patients with brain tumours but due to the number of images contained within a scan and the level of detail required, manual segmentation is a time consuming task. Convolutional neural networks have been proposed as tools for automated segmentation and shown promising results. LÄS MER

7. 5. Image-to-Image Translation for Improvement of Synthetic Thermal Infrared Training Data Using Generative Adversarial Networks

   Master-uppsats, Linköpings universitet/Datorseende

   Författare :Hanna Hamrell; [2021]
   Nyckelord :machine learning; deep learning; image-to-image translation; image processing; generative adversarial networks; infrared images; computer vision;

   Sammanfattning : Training data is an essential ingredient within supervised learning, yet time con-suming, expensive and for some applications impossible to retrieve. Thus it isof interest to use synthetic training data. However, the domain shift of syntheticdata makes it challenging to obtain good results when used as training data fordeep learning models. LÄS MER
