  1. 11. Classification of Financial Transactions using Lightweight Memory Networks

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

    Författare :Zhexin Cui; [2022]
    Nyckelord :Fraud Detection; Memory Network; Light-weight Model; Cryptocurrencies; Upptäckt av bedrägerier; minnesnätverk; lättviktsmodell; kryptovalutor;

    Sammanfattning : Various forms of fraud have substantially impacted our lives and caused considerable losses to some people. To reduce these losses, many researchers have devoted themselves to the study of fraud detection. LÄS MER

  3. 12. Applying Human-scale Understanding to Sensor-based Data : Generating Passive Feedback to Understand Urban Space Use

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Adam Eriksson; Hugo Uppling; [2021]
    Nyckelord :movement data modelling; urban space use; forecasting; time series; space syntax; Prophet; citizen passive feedback;

    Sammanfattning : The aim of this thesis is to investigate how parametrization of large-scale person movement data can contribute to describing the use of urban space. Given anonymous coordinate and timestamp data from a sensor observing an open-air mall, movement-based parameters are selected according to public life studies, behavioral mapping, and space syntax tools.

  4. 13. Monocular Visual Odometry for Autonomous Underwater Navigation : An analysis of learning-based monocular visual odometry approaches in underwater scenarios

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

    Författare :Andrea Caraffa; [2021]
    Nyckelord :Deep Learning; Monocular Visual Odometry; Computer Vision; Autonomous Underwater Navigation; Autonomous Underwater Vehicle; Djupinlärning; Monokulär Visuell Odometri; Datorseende; Autonom Undervattensnavigering; Autonomt Undervattensfordon;

    Sammanfattning : Visual Odometry (VO) is the process of estimating the relative motion of a vehicle by using solely image data gathered from the camera. In underwater environments, VO becomes extremely challenging but valuable since ordinary sensors for on-road localization are usually unpractical in these hostile environments. LÄS MER

  5. 14. En Komparativ Studie av Arkitekturen hos två NewSQL Databaser : En undersökning av VoltDB och CockroachDB

    Kandidat-uppsats, Jönköping University/Didaktik i Samhällsämnena

    Författare :Kim Berg; Rasmus Andersparr; [2021]
    Nyckelord :CockroachDB; VoltDB; NewSQL; CockroachDB; VoltDB; NewSQL; databas; databassystem; datatyper; datatypstransaktioner;

    Sammanfattning : The development of database systems is moving more and more towards handling large quantities of data, also known as Big Data. New database systems have been developed both within NoSQL and the newer system architecture called NewSQL used to tackle the problems that arise with Big Data. LÄS MER

  7. 15. Magnificent beasts of the Milky Way: Hunting down stars with unusual infrared properties using supervised machine learning

    Master-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Julia Ahlvind; [2021]
    Nyckelord :machine learning; supervised machine learning; support vector machine; photometry; stars; stellar physics; astronomical archives;

    Sammanfattning : The significant increase of astronomical data necessitates new strategies and developments to analyse a large amount of information, which no longer is efficient if done by hand. Supervised machine learning is an example of one such modern strategy. LÄS MER
