Training Progression

Details

This model is based on WGAN-GP.

The model was trained for ~9h40m on a GCE VM instance (n1-standard-4, 1 x NVIDIA T4).

The Critic consists of 4 Convolutional Layers with strides for downsampling, and Leaky ReLU activation. The critic does not use Batch Normalization or Dropout.

The Generator consists of 4 Transposed Convolutional Layers with ReLU activation and Batch Normalization.

The learning rate was kept constant at 1e-4 for the first 50,000 steps, which was followed by cosine annealing cycles with a peak LR of 1e-3.

The Lambda (gradient penalty coefficient) used was 10 (same as the original paper).
