1. 1. Neural Network-based Anomaly Detection Models and Interpretability Methods for Multivariate Time Series Data

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Deepthy Prasad; Swathi Hampapura Sripada; [2023]
   Nyckelord :multivariate - time series; anomaly detection; neural networks; autoencoders; interpretability; counterfactuals;

   Sammanfattning : Anomaly detection plays a crucial role in various domains, such as transportation, cybersecurity, and industrial monitoring, where the timely identification of unusual patterns or outliers is of utmost importance. Traditional statistical techniques have limitations in handling complex and highdimensional data, which motivates the use of deep learning approaches. LÄS MER

3. 2. Longitudinal Group Sequential Testing

   Magister-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Emil Lanzén; [2023]
   Nyckelord :;

   Sammanfattning : Sequential testing is used in clinical trials and online experiments to terminate trials early if there is sufficient evidence of a treatment effect, reducing the subjects’ exposure to potentially harmful treatments. However, incomplete follow-up of trial subjects can lead to biased estimation of the treatment effect. LÄS MER

4. 3. Reusage classification of damaged Paper Cores using Supervised Machine Learning

   M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Max Elofsson; Victor Larsson; [2023]
   Nyckelord :Machine Learning; Supervised Learning; classification; 3D sensor; TriSpector1008; SICK; paper core; paper mill; KNN; Support Vector Machine; Decision Trees; Random Forest; Maskininlärning; klassificering; papperskärna; pappersbruk;

   Sammanfattning : This paper consists of a project exploring the possibility to assess paper code reusability by measuring chuck damages utilizing a 3D sensor and usingMachine Learning to classify reusage. The paper cores are part of a rolling/unrolling system at a paper mill whereas a chuck is used to slow and eventually stop the revolving paper core, which creates damages that at a certain point is too grave for reuse.

5. 4. Detecting structural variants in the DNA of the inbred Scandinavian wolf

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Lars Huson; [2023]
   Nyckelord :animal; animal population; bioinformatics; biological sciences; biology; Canis lupus; CNV; conservation genetics; conservation genomics; copy-number variation; DNA; endangered population; endangered species; evolution; evolutionary biology; extinction; genetic diversity; genetics; genetic variation; genomes; genomics; grey wolf; inbreeding; inbreeding depression; indel; mutation; pedigree; population genetics; population genomics; Scandinavia; smoove; snakemake; structural variant; SV; wolf; wolves;

   Sammanfattning : Only 40 years ago, just three individuals made the journey from Finland/Russia to found the current wolf population in the southwest of Sweden. This population, that to this date descends from less than 10 founders, has a substantial increased extinction risk due to inbreeding. LÄS MER

7. 5. Facial recognition techniques comparison for in-field applications : Database setup and environmental influence of the access control

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

   Författare :Gustav Norvik; [2022]
   Nyckelord :facial recognition; deep learning; machine learning; computer vision; image processing; artificial intelligence;

   Sammanfattning : A currently ongoing project at Stanley Security is to develop a facial recognition system as access control system to prevent theft of heavy vehicles for terrorist purposes. As of today, there are several providers of facial recognition techniques and the spectrum ranges from multi dollar licenses to easy access open source. LÄS MER
