    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Johan Millberg; [2023]
    Keywords : clustering; machine learning; financial time series; time series; unsupervised learning; cluster validation; cluster evaluation; klustring; klusteranalys; finansiella tidsserier; maskininlärning; klustervalidering; evalueringsteknik;

    Abstract : This degree project aims to investigate different evaluation strategies for clustering methodsused to cluster multivariate financial time series. Clustering is a type of data mining techniquewith the purpose of partitioning a data set based on similarity to data points in the same cluster,and dissimilarity to data points in other clusters.

  3. 2. Narrow Pretraining of Deep Neural Networks : Exploring Autoencoder Pretraining for Anomaly Detection on Limited Datasets in Non-Natural Image Domains

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Matilda Eriksson; Astrid Johansson; [2022]
    Keywords : CNN; convolutional neural network; autoencoder; variational autoencoder; anomaly detection; SPADE; limited dataset; non-natural image domain; depth domain; scatter domain; intensity domain; machine learning;

    Abstract : Anomaly detection is the process of detecting samples in a dataset that are atypical or abnormal. Anomaly detection can for example be of great use in an industrial setting, where faults in the manufactured products need to be detected at an early stage. READ MORE

  4. 3. Parameter estimation in a cardiovascular computational model using numerical optimization : Patient simulation, searching for a digital twin

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

    Author : Giulia Tuccio; [2022]
    Keywords : Parameter estimation; Enhanced Scatter Search; Particle Swarm; Hooke and Jeeves; Cardiovascular Models; Parameteruppskattning; förbättrad spridningssökning; Particle Swarm; Hooke och Jeeves; kardiovaskulära modeller;

    Abstract : Developing models of the cardiovascular system that simulates the dynamic behavior of a virtual patient’s condition is fundamental in the medical domain for predictive outcome and hypothesis generation. These models are usually described through Ordinary Differential Equation (ODE). READ MORE
