  1. 21. Evaluating Membership Inference Attacks on Synthetic Data Generated With Formal Privacy Guarantees

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Elliot Beskow; Erik Lindé; [2023]
    Keywords : ;

    Abstract : Synthetic data generation using generative machine learning has been increasinglypublicized as a new tool for data anonymization. It promises to offer privacy whilemaintaining the statistical properties of the original dataset. This study focuses on the riskswith synthetic data by looking mainly at two aspects: privacy and utility. READ MORE

  3. 22. Anomaly Detection in Financial Transaction Time Series Data

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Leyla Abdul Kader; [2023]
    Keywords : ;

    Abstract : This master thesis investigates two methods of anomaly detection on financial time series data. It aims to determine an optimal method for anomaly detection with the purpose of flagging anomalous transactions within foreign exchange trading data. It also aims to determine whether the data points flagged as anomalies have any commonalities. READ MORE

  4. 23. RNN-based Graph Neural Network for Credit Load Application leveraging Rejected Customer Cases

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Oskar Nilsson; Benjamin Lilje; [2023]
    Keywords : Machine Learning; Deep Learning; Reject Inference; GNN; GCN; Graph Neural Networks; RNN; Recursive Neural Network; LSTM; Semi-Supervised Learning; Encoding; Decoding; Feature Elimination;

    Abstract : Machine learning plays a vital role in preventing financial losses within the banking industry, and still, a lot of state of the art and industry-standard approaches within the field neglect rejected customer information and the potential information that they hold to detect similar risk behavior.This thesis explores the possibility of including this information during training and utilizing transactional history through an LSTM to improve the detection of defaults.

  5. 24. Multi-scale Bark Beetle Predictions Using Machine Learning

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Albert Øhrman Wellendorf; [2023]
    Keywords : Geography; GIS; Geographically weighted regression; bark beetle; machine learning; Earth and Environmental Sciences;

    Abstract : Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. READ MORE

  6. 25. Processing world scale air traffic data to find Near Mid-Air Collisions

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Leopold Hermansson; [2023]
    Keywords : Air traffic safety; Detect and Avoid; ADS-B;

    Abstract : In order to increase the safety of all air travel, technologies that continueto augment the pilot's ability to avoid collisions and stay clear of danger areneeded. But, before these can be certified and deployed, their performance andpotential failure cases have to be understood. READ MORE
