By combining a variational autoencoder with a generative adversarial network we can use learned feature representations in the GAN discriminator as basis for the VAE reconstruction objective. Thereby, we replace element-wise errors with feature-wise errors to better capture the data distribution while offering invariance towards e.g. translation. is disentangled with respect to transformations such as out-of-plane rotations and lighting variations. The DC-IGN model is composed of multiple layers of convo-lution and de-convolution operators and is trained using the Stochastic Gradient Variational Bayes (SGVB) algorithm [11]. We propose a training procedure to Like GANs, variational autoencoders (VAEs) are often used to generate images. However, VAEs add an additional promise: namely, to model an underlying latent space. Here, we first look at a typical implementation that maximizes the evidence lower bound. Then, we compare it to one of the more recent competitors, MMD-VAE, from the Info-VAE (information maximizing VAE) family.Apr 19, 2017 · Explosive growth — All the named GAN variants cumulatively since 2014.

How to code the bottleneck of a Disentangled Variational Autoencoder (D-VAE) using Keras - Quora I can't find the 'D-VAE' paper (do you have a link?). However, if you mean the disentangling 'beta-vae' then it's a simple case of taking the vanilla VAE code and then using a beta>1 as multiplier of the Kullback Liebler term.

Abstract: We explore the use of Vector Quantized Variational AutoEncoder (VQ-VAE) models for large scale image generation. To this end, we scale and enhance the autoregressive priors used in VQ-VAE to generate synthetic samples of much higher coherence and fidelity than possible before.

Variational autoencoder (VAE) Variational autoencoders (VAEs) don’t learn to morph the data in and out of a compressed representation of itself. Instead, they learn the parameters of the probability distribution that the data came from. These types of autoencoders have much in common with latent factor analysis. Create an autoencoder in Python

In the variational autoencoder, the mean and variance are output by an inference network with parameters \(\theta\) that we optimize. The reparametrization trick lets us backpropagate (take derivatives using the chain rule) with respect to \(\theta\) through the objective (the ELBO) which is a function of samples of the latent variables \(z\).

Disentangled Sequential Autoencoder pared to the mentioned previous models that usually predict future frames conditioned on the observed sequences, we focus on learning the distribution of the video/audio content and dynamics to enable sequence generation without condi-tioning. Therefore our model can also generalise to unseen
