Why is Gaussian distribution? #14

Open kailugaji opened 2 years ago

kailugaji commented 2 years ago

Dear author, I don't quite understand one point. Is this representation Z discrete or continuous? If Z is discrete, why is the variational distribution Q simulated by Gaussian distribution instead of Bernoulli distribution?

Lin-Yijie commented 2 years ago

We suppose that the representation Z is continuous. Z could be understood as the distribution of discrete cluster assignment variables z.

Thank you for your reply and forgive my previous wrong understanding.
