it's not going to be able to be used for interactive dialogue any time soon even though it is able to generate very good lifelike audio waveforms the other major family of explicit tractable density models is the family of models based on the change of variables where we begin with a simple distribution like a Gaussian and we use a non-linear function to transform that distribution into another space so we transform from a latent space to on this slide the space of natural images the main drawback to this approach is that the
