Adversarials

Simple GAN

This is my attempt to make a wrapper class for a GAN in keras which can be used to abstract the whole architecture process.

Overview

Flow Chart

Setting up a Generative Adversarial Network involves having a discriminator and a generator working in tandem, with the ultimate goal being that the generator can come up with samples that are indistinguishable from valid samples by the discriminator.

Installation

    pip install adversarials

Example

import numpy as np
from keras.datasets import mnist

from adversarials.core import Log
from adversarials import SimpleGAN

if __name__ == '__main__':
    (X_train, _), (_, _) = mnist.load_data()

    # Rescale -1 to 1
    X_train = (X_train.astype(np.float32) - 127.5) / 127.5
    X_train = np.expand_dims(X_train, axis=3)

    Log.info('X_train.shape = {}'.format(X_train.shape))

    gan = SimpleGAN(save_to_dir="./assets/images",
    save_interval=20)
    gan.train(X_train, epochs=40)
