1. 1. 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

3. 2. 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

4. 3. Deep Learning for Iceberg Detection in Satellite Images

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Shuzhi Dong; [2021]
   Nyckelord :;

   Sammanfattning : The application of satellite images for ship and iceberg monitoring is essential in many ways in Arctic waters. Even though the detection of ships and icebergs in images is well established using Geoscience techniques, the discrimination between those two target classes still represents a challenge for operational scenarios.

5. 4. Cyberattacker - unika fall eller en möjlighet till lärande? : En kvalitativ fallstudie av den nationella hanteringen av cyberattacker inom Sverige

   Kandidat-uppsats, Försvarshögskolan

   Författare :Olivia Malmström; [2021]
   Nyckelord :;

   Sammanfattning : In the last decades the world has become more and more digitalized which has led to a new kind of threat, known as cyberattacks. The statistics show that the amount of attacks are increasing every year even though the increasing experience should help to contain the threat. LÄS MER

7. 5. Furniture swap : Segmentation and 3D rotation of natural images using deep learning

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Emanuel Bodin; [2021]
   Nyckelord :;

   Sammanfattning : Learning to perceive scenes and objects from 2D images as 3D models is atrivial task for a human but very challenging for a computer. Being ableto retrieve a 3D model from a scene just by taking a picture of it canbe of great use in many fields, for example when making 3D blueprintsfor buildings or working with animations in the game or film industry.
