for flow models and also how do how do you carefully initialize so that flow models can train very fast so in terms of core achievements that you can aim for you can aim for producing low level samples which are truer models that have way fewer parameters the globe uses half a billion parameters for all the celebrity faces and that's unlikely a scale and how do you make it work potentially for even larger images how do you do dimensionality reduction with flows and think about other other flow models like conditional flow models and
