  • Estimation of the iVAE Model with Generative Adversarial Networks 
    Luopajärvi, Kalle (2022)
    In independent component analysis the data is decomposed into its statistically independent components. In recent years, statistical models have been developed that solve a non-linear version of the independent component analysis. This thesis focuses on the estimation methods of a particular non-linear independent component analysis model called iVAE. It is shown on simulated data that the generative adversarial networks can significantly improve the iVAE model estimation compared with the previously used default iVAE estimation method. The improved model estimation might enable new applications for the iVAE model.
