What criteria did you use to select which model to use for generation?

Thank you for your amazing project!

I have a question about your project!
What criteria did you use to select which model to use for generation?
I noticed that among the pretrained models you provided, the “rearrange” model(bedroom) is trained for 16,000 epochs. 
When generating, which epoch’s model do you choose, and what criteria do you use to decide which epoch to use?
