Sth about the Loss Function

[ZhouYiiFeng]

Hi,

I notice that this model is based on the "flow-based generative model", however, the loss does not include the logdet loss. The cal_jacobian is default set to False. Is this cause by you replaced some features of the forward output by the normal distribution?

I‘m new in learning the "flow-based generative model", maybe I got it wrong, could you help me? Thx!

It is just because there is no need to calculate the Jacobian. Calculating Jacobian is to get the accurate log-likelihood. However, in our task, we don't care about the log-likelihood of z. Setting it false can speed up the training.

Sure.
