LogVar layer of a VAE only returns zeros
I'm building a Variational auto encoder (VAE) with tfjs.
For now I'm only exploring with the fashionMNIST dataset and a simple model as follows:
input layer (28*28*1)
flatten
intermediate_1 (dense 50 ...

Is it Possible to feed Embeddings generate by BERT to a LSTM based autoencoder to get the latent space?
I've just learn about how BERT produce embeddings. I might not understand it fully.
I was thinking of doing a project of leveraging those embeddings and feed it to an autoencoder to generate latent ...

Facing ResourceExhaustedError while training an autoencoder using k-fold cross validation
I'm trying to train an stacked denoising autoencoder. Also, since I have a small data set, I implement 10-fold cross validation to find the best hyperprameters. In every fold I build a new model and ...

VAE with Gumbel softmax on MNIST dataset
What could be the issue of kl loss going to 0? reconstruction loss is small, but every image is the same, and does not represent any digit.
Here is my encoder/decoder architecture I used, I think the ...
