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. Performance comparison of data mining algorithms for imbalanced and high-dimensional data

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

   Författare :Daniel Rubio Adeva; [2023]
   Nyckelord :Data science; neural network; random forest; support vector machine; imbalanced data; average precision; ROC; Datavetenskap; neuralt nätverk; slumpmässig skog; stödvektormaskin; obalanserad data; medelprecision; ROC;

   Sammanfattning : Artificial intelligence techniques, such as artificial neural networks, random forests, or support vector machines, have been used to address a variety of problems in numerous industries. However, in many cases, models have to deal with issues such as imbalanced data or high multi-dimensionality. LÄS MER

4. 3. Centralised MPC for Long-term Voltage Stability Control of Power System

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

   Författare :Johan Hallberg; [2023]
   Nyckelord :Voltage stability; Model predictive control; Tap-changing transformer; Capacitor bank; Spänningsstabilitet; Model prediktiv reglering; Lindningskopplare; Kondensatorbank;

   Sammanfattning : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. LÄS MER

5. 4. I'll have what he's having : can a bank increase the financial equality?

   Master-uppsats, SLU/Dept. of Forest Economics

   Författare :Cecilia Olander; [2022]
   Nyckelord :Economics; Entrepreneurs; Equality; Feminist theory; Finance; Strategy; Sustainable business models; Sustainability reporting; Sustainability strategy;

   Sammanfattning : In Sweden, women own half as much as men, in the agricultural sector only 18% of business owners are women. Women tend to be viewed as more risk-averse than men by bank officials. Research has shown that young entrepreneurs are described differently depending on their genders. LÄS MER

7. 5. Detecting Chargebacks in Transaction Data with Artificial Neural Networks

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

   Författare :Theodor Günther; Otto Pagels-Fick; [2022]
   Nyckelord :Artificial Neural network; Chargeback; Fraud; Machine learning;

   Sammanfattning : The chargeback process is costly for the merchant. Not only does the merchant lose the revenue from the purchase, but it must also pay handling fees to the bank and risks never getting paid for provided service. LÄS MER
