1. 21. Anomaly Detection of Time Series Caused by International Revenue Share Fraud : Additive Model and Autoencoder Applications

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

   Author : Lingxiao Wang; [2023]
   Keywords : Fraud detection; Anomaly detection; Machine learning; Bedrägeriupptäckt; Anomalidetektering; Maskininlärning;

   Abstract : In this paper, we compare the performance of two methods to find the attempts at fraud from the data provided by Sinch (formerly CLX Communications, which is a telecommunications and cloud communications platform as a service (PaaS) company). We consider the problem as finding the anomaly in a time series signal, where we ignore the duration of a single call or other features and only care about the total volume of calls in a certain period.

3. 22. Predicting tumour growth-driving interactions from transcriptomic data using machine learning

   University essay from Uppsala universitet/Neuroonkologi och neurodegeneration

   Author : Mathilda Stigenberg; [2023]
   Keywords : cancer; immunology; cell-cell interactions; deep learning; variational autoencoder; supervised variational autoencoder; tumour microenvironment; single-cell RNA sequencing; spatial transcriptomics; breast cancer; machine learning;

   Abstract : The mortality rate is high for cancer patients and treatments are only efficient in a fraction of patients. To be able to cure more patients, new treatments need to be invented. Immunotherapy activates the immune system to fight against cancer and one treatment targets immune checkpoints. READ MORE

4. 23. W2R: an ensemble Anomaly detection model inspired by language models for web application firewalls security

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Zelong Wang; Athira AnilKumar; [2023]
   Keywords : web application firewall; anomaly detection; word2vec; BERT; dimension reduction; ensemble model;

   Abstract : Nowadays, web application attacks have increased tremendously due to the large number of users and applications. Thus, industries are paying more attention to using Web application Firewalls and improving their security which acts as a shield between the app and the internet by filtering and monitoring the HTTP traffic.

5. 24. Deep Learning for the prediction of RASER-MRI profiles

   University essay from Linköpings universitet/Medie- och Informationsteknik

   Author : Filip Arvidsson; Jonas Bertilson; [2023]
   Keywords : MRI; NMR; AI; Deep Learning; RASER-MRI; Media Technology; KIT; LIU; CNN; Autoencoder; Djupinlärning; Medieteknik; Magnetröntgen;

   Abstract : Magnetic resonance imaging (MRI) is a critical diagnostic tool in medical practice, enabling non-invasive visualization of anatomy and physiological processes. Nonetheless, MRI has inherent spatial resolution limitations, which may limit its diagnostic capabilities. READ MORE

6. 25. Estimating Poolability of Transport Demand Using Shipment Encoding : Designing and building a tool that estimates different poolability types of shipment groups using dimensionality reduction.

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

   Author : Marvin Kërçini; [2023]
   Keywords : Poolability; Transport networks; Autoencoder; Dimensionality reduction; Vehicle Routing Problem; Raggruppabilità; Reti di trasporto; Autoencoder; Riduzione della dimensionalità; Vehicle Routing Problem; Poolbarhet; Transportnätverk; Autokodare; Dimensionsreduktion; Fordonsdirigeringsproblem;

   Abstract : Dedicating less transport resources by grouping goods to be shipped together, or pooling as we name it, has a very crucial role in saving costs in transport networks. Nonetheless, it is not so easy to estimate pooling among different groups of shipments or understand why these groups are poolable. READ MORE
