pytorch-MNIST-CelebA-cGAN-cDCGAN
Pytorch implementation of conditional Generative Adversarial Networks (cGAN) [1] and conditional Generative Adversarial Networks (cDCGAN) for MNIST [2] and CelebA [3] datasets.
-
The network architecture (number of layer, layer size and activation function etc.) of this code differs from the paper.
-
CelebA dataset used gender lable as condition.
-
If you want to train using cropped CelebA dataset, you have to change isCrop = False to isCrop = True.

Resutls
MNIST
- Generate using fixed noise (fixed_z_)

- Learning Time
- MNIST cGAN - Avg. per epoch: 9.13 sec; Total 50 epochs: 937.06 sec
- MNIST cDCGAN - Avg. per epoch: 47.16 sec; Total 20 epochs: 1024.26 sec
CelebA
- Generate using fixed noise (fixed_z_; odd line - female (y: 0) & even line - male (y: 1); each two lines have the same style (1-2) & (3-4).)
| cDCGAN | cDCGAN crop |
