# CATS - Deep Convolutional Generative Adversarial Network
This repository serves as an example of how to generate images of cat faces using a [Deep Convolutional Generative Adversarial Network](https://arxiv.org/pdf/1511.06434.pdf) (DCGAN) developed by [@Rapsssito](https://github.com/rapsssito) and [@pablotix20](https://github.com/pablotix20). It is heavily inspired by [TensorFlow's tutorial](https://www.tensorflow.org/tutorials/generative/dcgan) about this topic. This repository does not provide a training dataset, but several are available online:
* [`fferlito/Cat-faces-dataset`](https://github.com/fferlito/Cat-faces-dataset)
* [`Cats faces 64x64`](https://www.kaggle.com/spandan2/cats-faces-64x64-for-generative-models)
## Our model
Our particular model, provided in [cats_gan.ipynb](./cats_gan.ipynb), uses more than 30k 64x64 resized RGB images of cat faces as the training dataset. Below the structures for the generator and discriminator are provided:
