  1. 6. Meeting electricity demand during a crisis : Assessing the feasibility of battery storage as a path for municipalities to increase electricity resilience

    University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Author : Maria Lindström; Malou Sjöberg; Filip Sjöö; Hanna Åkermark; [2023]
    Keywords : Battery storage; Electricity demand; Crisis preparedness; Socio-technical analysis; Electricity resilience; Household responsibility; Municipal responsibility; Knivsta kommun;

    Abstract : This bachelor thesis aims to investigate household electricity supply and demand during a crisis. Both quantitative and qualitative aspects of crisis preparedness and household electricity demand are considered. READ MORE

  3. 7. Regularizing Vision-Transformers Using Gumbel-Softmax Distributions on Echocardiography Data

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

    Author : Alfred Nilsson; [2023]
    Keywords : Deep Learning; Vision-Transformers; Echocardiography; Feature Selection; Gumbel-Softmax; Concrete Autoencoders; Regression; Djupinlärning; Vision-Transformers; Ekokardiografi; Feature Selection; GumbelSoftmax; Concrete Autoencoders; Regression;

    Abstract : This thesis introduces an novel approach to model regularization in Vision Transformers (ViTs), a category of deep learning models. It employs stochastic embedded feature selection within the context of echocardiography video analysis, specifically focusing on the EchoNet-Dynamic dataset. READ MORE

  4. 8. Evaluating clustering techniques in financial time series

    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.

  5. 9. Analysing Regime-Switching and Cointegration with Hamiltonian Monte Carlo

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Jakob Brandt; [2023]
    Keywords : Time Series Econometrics; Regime-Switching; Cointegration; Markov Chain Monte Carlo; Hamiltonian Monte Carlo;

    Abstract : The statistical analysis of cointegration is crucial for inferring shared stochastic trends between variables and is an important area of Econometrics for analyzing long-term equilibriums in the economy. Bayesian inference of cointegration involves the identification of cointegrating vectors that are determined up to arbitrary linear combinations, for which the Gibbs sampler is often used to simulate draws from the posterior distribution.

  6. 10. Optimal Multitaper Spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Markus Ydreskog; [2023]
    Keywords : Time-frequency analysis; Multitaper spectrogram; Optimization; Wigner distribution; Mathematics and Statistics;

    Abstract : Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. READ MORE
