GANs were invented by Ian Goodfellow in 2014 and first described in the paper
Generative Adversarial Nets https://papers.nips.cc/paper/5423-generative-adversarial-nets.pdf
Unsupervised Representation Learning With Deep Convolutional Generative Adversarial Networks
It was first described by Radford et. al. in the paper
https://arxiv.org/pdf/1511.06434.pdf.

some awesome applications about gans
https://github.com/nashory/gans-awesome-applications
we will use the Celeb-A Faces dataset which can be downloaded at the linked site,
paper: Deep Learning Face Attributes in the Wild
dataset web http://mmlab.ie.cuhk.edu.hk/projects/CelebA.html
Download link:
Baidu Drive https://pan.baidu.com/s/1eSNpdRG#list/path=%2F
Google Drive https://drive.google.com/drive/folders/0B7EVK8r0v71pTUZsaXdaSnZBZzg
The dataset will download as a file named img_align_celeba.zip.
Once downloaded, create a directory named celeba and extract the zip file into that directory.
Then, set the dataroot input for this notebook to the celeba directory you just created.
The resulting directory structure should be:
/path/to/celeba
-> img_align_celeba
-> 188242.jpg
-> 173822.jpg
-> 284702.jpg
-> 537394.jpg
...
This is an important step because we will be using the ImageFolder dataset class,
which requires there to be subdirectories in the dataset’s root folder.
Now, we can create the dataset, create the dataloader,
set the device to run on, and finally visualize some of the training data.
how to run a test?
bash run.shIt could work.
In priciple,the GAN optimization game is simple,the gibberish is typical
for a generator trained without proper care! gan is hard to train. such as:
Tried the resize code for 128x128 and finding that the Discriminator flatlines to 0.0000
A couple of tricks are necessary for to facilitate training.
