Web8 de jul. de 2024 · We propose Nouveau VAE (NVAE), a deep hierarchical VAE built for image generation using depth-wise separable convolutions and batch normalization. NVAE is equipped with a residual parameterization of Normal distributions and its training is stabilized by spectral regularization. We show that NVAE achieves state-of-the-art … Webto perform inpainting on the codemaps of the VQ-VAE-2, which allows to sam-ple new sounds by first autoregressively sampling from the factorized distribution p(c top)p(c bottomjc top) thendecodingthesesequences. 3.3 Spectrogram Transformers After training the VQ-VAE, the continuous-valued spectrograms can be re-
