flux-vae

This repository accompanies my blog post "Convolutional VAE in Flux" where we take a look at variational autoencoders and do a walk-through demo of a Flux implementation of a convolutional VAE using the FashionMNIST benchmark dataset.

Training

You can train the model directly from these scripts by running the following in your terminal:

julia --project=vaeenv conv-vae/main.jl

You should see a progress tracker and the training loss displayed in your terminal.

Visualisation

Similarly, you can visualise reconstructed images from the test set by running:

julia --project=vaeenv conv-vae/visualise.jl

Some original test set samples (on the left) with the coresponding reconstructions (on the right):
