Web14 de set. de 2024 · Image pipeline. The input representations obtained from VGG-19 or ResNet-152 are fed into our joint Wasserstein autoencoder. The image encoder takes 4096 inputs (2048 for ResNet-152), which are fully connected to a hidden layer of 2048 nodes. The encoder outputs into a d -dimensional latent space.
