  1. 1. Detecting Social Breathing : Quantitative signs of interaction in conversational data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Cordelia Horns; [2022]
    Keywords : time series; interaction; human interaction; data analysis; wavelet analysis; machine learning; Social Breathing;

    Abstract : Human interaction has been a focus of study in psychology for a long time, but until recentlyonly very specific aspects of interaction have been considered. This approach leads to studiesthat gave insights into certain contexts, like parent-child or patient-clinician dynamics [1], [2]. READ MORE

  3. 2. Statistics and Machine Learning for Classification of Emotional and Semantic Content of EEG

    University essay from Lunds universitet/Matematisk statistik

    Author : Oskar Keding; David Ohlin; [2021]
    Keywords : Machine Learning; machine; learning; neural; network; statistics; EEG; emotion; semantic; emotional; signal; processing; reassignment; time-frequency; spectrogram; brain processing; bci; CNN; convolutional; Mathematics and Statistics;

    Abstract : Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. READ MORE

  4. 3. Clinical dose feature extraction for prediction of dose mimicking parameters

    University essay from KTH/Matematik (Avd.)

    Author : Anton Finnson; [2021]
    Keywords : Radiation therapy; feature extraction; wavelets; treatment planning; dose mimicking; variational autoencoder; Strålterapi; wavelets; doshärmning;

    Abstract : Treating cancer with radiotherapy requires precise planning. Several planning pipelines rely on reference dose mimicking, where one tries to find machine parameters best mimicking a given reference dose. Dose mimicking relies on having a function that quantifies dose similarity well, necessitating methods for feature extraction of dose images. READ MORE

  5. 4. Statistics and machine learning for classification of emotional and semantic content of EEG

    University essay from Lunds universitet/Teknisk matematik (CI); Lunds universitet/Institutionen för reglerteknik

    Author : David Ohlin; Oskar Keding; [2021]
    Keywords : Technology and Engineering;

    Abstract : Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. READ MORE

  6. 5. The Discrete Wavelet Transform

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Wirén Anton; [2021]
    Keywords : Wavelet theory; multiresolution analysis; image processing.;

    Abstract : In this thesis we will explore the theory behind wavelets. The main focus is on the discrete wavelet transform, although to reach this goal we will also introduce the discrete Fourier transform as it allow us to derive important properties related to wavelet theory, such as the multiresolution analysis.
