  1. 1. More efficient training using equivariant neural networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Karl Bylander; [2023]
    Nyckelord :convolutional neural networks; equivariance; equivariant neural networks; transmission electron microscopy; machine learning;

    Sammanfattning : Convolutional neural networks are equivariant to translations; equivariance to other symmetries, however, is not defined and the class output may vary depending on the input's orientation. To mitigate this, the training data can be augmented at the cost of increased redundancy in the model. LÄS MER

  3. 2. Group Invariant Convolutional Boltzmann Machines

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Maria Lindström; [2020-12-04]
    Nyckelord :Convolutional Boltzmann Machines; Convolutional neural networks; artificial neural networks; machine learning; group invariance; group equivariance;

    Sammanfattning : We investigate group invariance in unsupervised learning in the context of certain generative networks based on Boltzmann machines. Specifically, we introduce a generalization of restricted Boltzmann machines which is adapted to input data that is acted upon by any compact group G. LÄS MER
