About the random latent variables(z1,2,3).

[XingliangJin]

Hi! I am very interested in your wonderful job.
In your paper, you mentioned using random latent variables(z1,2,3) to generate diverse stylized results. I would like to know how these random latent variables(z1,2,3) are obtained from the original random noise. What is the difference between them? I am so sorry if these questions bother you. Thank you so much!
