We present new intuitions and theoretical assessments of the emergence of disentangled representation in variational autoencoders. The resulting model, however, had some drawbacks:Not all the numbers turned out to be well encoded in the latent space: some of the numbers were either completely absent or were very blurry. All energies are given in GeV. The VAE encoder has the added benefit of stochastically embedding the cells to reflect the model’s uncertainty. GAN, VAE in Pytorch and Tensorflow.
