The input to the model is a noise vector of shape (N, 120) where N is the number of images to be generated. It can be constructed using the function .buildNoiseData. The model has a .test function that takes in the noise vector and generates images.

num_images = 64
noise, _ = model.buildNoiseData(num_images)
generated_images = model.test(noise)

# let's plot these images using torchvision and matplotlib
import matplotlib.pyplot as plt
import torchvision
plt.imshow(torchvision.utils.make_grid(generated_images).permute(1, 2, 0).cpu().numpy())
# plt.show()


You should see an image similar to the one on the left.

If you want to train your own DCGAN and other GANs from scratch, have a look at PyTorch GAN Zoo.

### Model Description

In computer vision, generative models are networks trained to create images from a given input. In our case, we consider a specific kind of generative networks: GANs (Generative Adversarial Networks) which learn to map a random vector with a realistic image generation.

DCGAN is a model designed in 2015 by Radford et. al. in the paper Unsupervised Representation Learning with Deep Convolutional Generative Adversarial Networks. It is a GAN architecture both very simple and efficient for low resolution image generation (up to 64x64).

### Requirements

• Currently only supports Python 3
