Thank you very much. It seems that VAE could be a nice choice for me.

Anyway, by plotting the cluster map it seems that there are several features higly correlated, but also a lots of feature with low correlation

Thank you very much for these pointers!

I will investigate

I will try to check this, I didn't think about it.

The only way Clustering came to my mind was for extracting some clusters and then using them as a label to evaluate my features.

I am trying also to implement a penalization in the latent representation by applying the norm of the jacobian matrix, but since I see no one using it, I was thinking that was wrong in Convolutional AE (and also the paper use a different definition from the one that I am using).

Yes, I know that I can calculate the jacobian with autograd, but the problem is that in the paper they use a particular formulation given that they have sigmoid non-linearity https://ibb.co/8xGQkZ6.

Regarding MC and t-SNE, I will investigate.
