pytorch-MNIST-CelebA-GAN-DCGAN

Pytorch implementation of Generative Adversarial Networks (GAN) [1] and Deep Convolutional Generative Adversarial Networks (DCGAN) [2] for MNIST [3] and CelebA [4] datasets.

  • If you want to train using cropped CelebA dataset, you have to change isCrop = False to isCrop = True.

  • you can download

  • pytorch_CelebA_DCGAN.py requires 64 x 64 size image, so you have to resize CelebA dataset (celebA_data_preprocess.py).

  • pytorch_CelebA_DCGAN.py added learning rate decay code.

Resutls

MNIST

  • Generate using fixed noise (fixed_z_)
GAN DCGAN
  • MNIST vs Generated images
MNIST GAN after 100 epochs DCGAN after 20 epochs

  • Training loss

    • GAN Loss

  • Learning Time

    • MNIST DCGAN - Avg. per epoch: 197.86 sec; (if you want to reduce learning time, you can change 'generator(128)' and 'discriminator(128)' to 'generator(64)' and 'discriminator(64)' ... then Avg. per epoch: about 67sec in my development environment.)

CelebA

  • Generate using fixed noise (fixed_z_)
DCGAN DCGAN crop
  • CelebA vs Generated images
CelebA DCGAN after 20 epochs DCGAN crop after 30 epochs
  • Learning Time
    • CelebA DCGAN - Avg. per epoch: 732.54 sec; total 20 epochs ptime: 14744.66 sec
