### Is plain autoencoder a generative model?

An autoencoder is not considered a generative model, because it only reconstructs the given input. You could use the decoder like a generative model by putting in different vectors. However, the ...

### How to generate new data given a trained VAE - sample from the learned latent space or from multivariate Gaussian?

Maybe there's a misconception, we are not learning a mu and log_var but a mapping (encoder) from an image to ...

### How to generate new data given a trained VAE - sample from the learned latent space or from multivariate Gaussian?

I think method 1 will provide the best output. Approximating the empirical distribution of $z$ should provide decoder inputs in the subset of latent space that the decoder was trained on. Sampling ...

### Why don't we also need to approximate $p(x \mid z)$ in the VAE?
What I can guess here is that, in VAEs, we assume $p(z)$ (prior), so we are able to calculate $p(x \mid z)$, but for $p(x)$ we can't assume its distribution? Is it right? You could assume $p(x)$ is ...
