Abstract
Zadatak ovog rada je bio uvod u osnovne pojmove i koncepte VQ-VAE modela te uspostaviti vezu s već definiranim varijacijskim autoenkoderima. Uz to, cilj je bio predstaviti osnovne matematičke izvode za definiranje VQ-VAE modela, kao što su varijacijska inferencija, rekonstrukcijski gubitak, regularizacijski gubitak i gubitak kvantizacije. Zatim je provedeno izvod̄enje varijacijskih autoenkodera i VQ-VAE modele te njihovo treniranje na jednostavnijem skupu slika (konkretno, MNIST slika znamenki) kako bi se istražila njihova sposobnost rekonstrukcije slika. Takod̄er je bilo potrebno odabrati odred̄enu javno dostupnu prednaučenu arhitekturu i provesti ispitivanje nad njom. Potom su prikazani dobiveni rezultati provedenih ispitivanja te su izvedeni zaključci o performansama ispitanih arhitektura.
Abstract (english)
This study aimed to provide an introduction to the fundamental concepts and principles of the VQ-VAE model and establish a connection with the already defined variational autoencoders. Additionally, the goal was to present the basic mathematical derivations for defining the VQ-VAE model, such as variational inference, reconstruction loss, regularization loss, and quantization loss. Furthermore, variational autoencoders and VQ-VAE models were derived and trained on a more specific dataset of images (specifically, MNIST digit images) to explore their ability to reconstruct images. It was also necessary to select a specific publicly available pre-trained architecture and evaluate it. Subsequently, the obtained results of the conducted evaluations were presented, and conclusions were drawn regarding the performance of the examined architectures.
