Query regarding KL divergence loss

Hi,
Thanks for making the code available.
I have a query in the KL divergence loss term, where the KL loss between ID excluded attribute representation and the Gaussian distribution is tried to be minimised.
Actually I don't understand why is this loss written this way in code, some indices are chosen at att_ex_idx and values at those indices are given to compute_kl method. First, what does those indices signify and second in the compute_kl method, it just computes the mean of the square of the values.
I also want to add a smiilar loss in my work. Please redirect me to some resource which gives some explanation about the closed form solution for KL divergence between the latent variable and Gaussian distribution.

Thanks a lot in advance!

About the CE loss

Dear scholar,
Could you give me the link about the supplementary materials that was mentioned in your paper? And maybe the introduction of CE loss part is very brief. I want to ask you whether feature fi(from di com) is followed by a classifier to get the CE loss. And how to decide the number of nodes in the classifier? I guess the number of nodes in classifier maybe the number of ids in the training set such as 206 or 395.

About GPU memory

Excuse me.
If my GPU memory is 8, how can I modify it to make the code run?
Thank you!!
