WebReview 2. Summary and Contributions: The paper proposes a bidirectional hierarchical VAE architecture, that couples the prior and the posterior via a residual parametrization and a combination of training tricks, and achieves sota results among non-autoregressive, latent variable models on natural images.The final, however, predictive likelihood achieved is … WebWe demonstrate that a multi-scale hierarchical organization of VQ-VAE, augmented with powerful priors over the latent codes, is able to generate samples with quality that rivals that of state of the art Generative Adversarial Networks on multifaceted datasets such as ImageNet, while not suffering from GAN's known shortcomings such as mode collapse …
WebThe proposed model is inspired by the hierarchical vector quantized variational auto-encoder (VQ-VAE), whose hierarchical architecture disentangles structural and textural … Webexperiments). We use the released VQ-VAE implementation in the Sonnet library 2 3. 3 Method The proposed method follows a two-stage approach: first, we train a hierarchical VQ-VAE (see Fig. 2a) to encode images onto a discrete latent space, and then we fit a powerful PixelCNN prior over the discrete latent space induced by all the data.
