Describe the bug
When running the GMM preprocessing, we are seeing poor correlations coming out of the trained VAE. Investigate this further.

To Reproduce
Steps to reproduce the behavior:

  1. Run any training setup involving GMM preprocessing
  2. Compare correlations from original and generated data via something like .corr()

Expected behavior
Some closer matching of correlations of between generated data and original data when using GMM preprocessing

Additional context
Comparison to TVAE in CTGAN from SDV is worth utilising (https://github.com/sdv-dev/CTGAN)
