  1. 21. Automatic Speech Recognition Model for Swedish using Kaldi

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yihan Wang; [2020]
    Nyckelord :Speech recognition; Kaldi; Mel-frequency cepstral coefficient; Perceptual linear predictive; Speaker adaptive training; Weight Finite State Transducers; Taligenkänning; Kaldi; Cefstralskoefficient för Mel-Frekvens; Perceptuell linjär prediktiv; Uppladdning av högtalaren; Viktfinitomvandlare;

    Sammanfattning : With the development of intelligent era, speech recognition has been a hottopic. Although many automatic speech recognition(ASR) tools have beenput into the market, a considerable number of them do not support Swedishbecause of its small number. LÄS MER

  3. 22. Green Fuel Simulations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Daniel Gutiérrez; [2020]
    Nyckelord :Industrial gas turbines; Combustion instabilities; Computational fluid dynamics; Acoustics; COMSOL Multiphysics; Flame transfer function;

    Sammanfattning : Many industries have entered a new global phase which takes the environment in mind. The gas turbine industry is no exception, where the utilization of green fuels is the future to spare the environment from carbon dioxide and NOx emissions. LÄS MER

  4. 23. Attractors of autoencoders : Memorization in neural networks

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Jonas Strandqvist; [2020]
    Nyckelord :machine learning; overfitting; memorization; neural network; autoencoder; attractor; Jacobian; eigenvalue; CIFAR10; random data; ReLU; bias;

    Sammanfattning : It is an important question in machine learning to understand how neural networks learn. This thesis sheds further light onto this by studying autoencoder neural networks which can memorize data by storing it as attractors. LÄS MER

  5. 24. Quantum Optimization

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Luca Bernecker; [2020]
    Nyckelord :Quantum; Optimization; HHL; VQE; Optimisation; Physics; Physics and Astronomy;

    Sammanfattning : This thesis concerns the implementation of quantum algorithms on a computer vision problem called bundle adjustment. Bundle adjustment can be simplified for illustration purposes by the following example. Two different cameras take a picture of the same object in different angles. LÄS MER

  7. 25. Computation of Eigenmodes in Three-Dimensional Structures

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Daniel Lilja; Olof Hummelgren; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis the eigenmodes and eigenvalues of three dimensional structures are analyzed using the Python environment FEniCS in combination with an implementation of the Arnoldi method in MATLAB for calculation of eigenpairs. This is done by considering separable solutions of the wave equation and subsequently expressing these as the solutions to an eigenvalue problem. LÄS MER
