Can VAEs be used to generate multivariate data?

Data Science Asked on January 31, 2021

Most of the tutorials online seem to use VAEs to generate images and use CNNs to generate data. I am working on a game with multivariate data consisting of character position and the character attributes to train a VAE.

I was wondering if it was possible because I have tried training the network with pytorch but I continue to get poor results with KL Divergence term decreasing to 0.

Any help would be really appreciated.

Sure can look at this multivariate timeseries for example: enter image description here

It has nothing to do with pytorch, input is input, regardless. See this paper

The CTGAN paper (github) use a VAE to generate multivariate synthetic data from tabular data. See section 4.5.
