  1. 1. Unauthorised Session Detection with RNN-LSTM Models and Topological Data Analysis

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Nazar Maksymchuk Netterström; [2023]
    Nyckelord :Recurrent Neural Network; Long-Short-Term-Memory; Topological Data Analysis; Session based data; Anomaly detection; Time-series analysis; Imbalanced data; Master thesis; Neurala nätverk; Topologisk data analys; Detektion av avvikelse; Sessionsbaserad data; Tidserieanalys; Inbalancerad data; Masteruppsats;

    Sammanfattning : This thesis explores the possibility of using session-based customers data from Svenska Handelsbanken AB to detect fraudulent sessions. Tools within Topological Data Analysis are employed to analyse customers behavior and examine topological properties such as homology and stable rank at the individual level. LÄS MER

  3. 2. Joint CFR and DPD optimization for 5G Digital Front Ends

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Gustav Olsson; [2023]
    Nyckelord :Crest Factor Reduction; Digital Pre-Distortion; Power Amplifier; Parameter Optimization; 5G; Base Station; Memory Polynomial; Technology and Engineering;

    Sammanfattning : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

  4. 3. Från entusiasm och engagemang till tårar och ängslan : En fenomenografisk studie kring summativa bedömningssituationer i matematik ur ett elevperspektiv

    Uppsats för yrkesexamina på avancerad nivå, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Marie Karlsson; Camilla Hahne; [2023]
    Nyckelord :mathematics; mathematics anxiety; special education; SUM; summative assessment; matematik; matematikängsla; specialpedagogik; SUM; summativ bedömning;

    Sammanfattning : Skolans uppdrag är att säkerhetsställa att alla elever har samma möjligheter att tillgodogöra sig kunskap och därmed utvecklas. Alla elever lär sig på olika vis och har också behov av att visa sina kunskaper på olika sätt. LÄS MER

  5. 4. Deep Learning Based Out-of-focus Detection on Surveillance Footage

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Hanna Bengtsson; Teodora Kerac; [2023]
    Nyckelord :Deep Learning; CNN; Out-of-focus detection; Mathematics and Statistics;

    Sammanfattning : Loss of focus in surveillance cameras can occur due to factors such as environmental aspects, sabotage or system errors. The focus loss leads to degraded footage that is of no use for either post-investigation or automatic video analysis. LÄS MER

  7. 5. Learning Based Road Estimation

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Sanna Amirijoo; Karl Niwong; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The interest in autonomous driving has vastly increased, leading to a surge in research and development efforts over the past decades. This technology could enhance road safety, alleviate traffic congestion, and yield numerous environmental and economic benefits. LÄS MER
