The proposed model is called Vector Quantized Variational Autoencoders (VQ-VAE). That’s how to think about deep neural networks going through the “training” phase. While this leads to the main advantage of quantile regression, namely that the shape of the distribution need not be specified by the modeller, one potential drawback is the possibility of quantile crossing, in which estimated quantile.
