Generative Adversarial Network (GAN) is a powerful deep learning model, which consists of two networks of generator and discriminator, and realizes the ability to generate data through confrontation training. As research progressed, many variants of GANs emerged, each with its own unique improvements and characteristics. Here are some common GAN variants:
1.DCGAN（Deep Convolutional GAN）：
- DCGAN is a variant of GAN based on convolutional neural networks, which uses convolutional layers and transposed convolutional layers to achieve image generation. DCGAN can better capture the characteristics of images and generate higher quality images by using convolutional layers to process image data.
2.WGAN（Wasserstein GAN）：
- WGAN is a variant of GAN based on Wasserstein distance, which improves the stability of training and the quality of generated samples by changing the loss function of GAN. WGAN uses the Wasserstein distance to measure the difference between the real distribution and the generated distribution, so as to better guide the training process of the generator.
3.CGAN（Conditional GAN）：
- CGAN is a conditional GAN variant, which introduces additional conditional vectors as input, enabling the generator to generate corresponding samples according to the given conditions. CGAN considers additional conditional information during generation, such as labels or categories, which can be used to generate category-specific samples.
4.CycleGAN：
- CycleGAN is a GAN variant for image translation that enables image style transfer without the need for paired training data. CycleGAN uses a cycle consistency loss to constrain the generator such that the generated images are transferable between different domains.
