PGGAN (Progressive Growing GAN)

Progressive Growing GAN (PGGAN) is a type of artificial intelligence that creates realistic images by gradually increasing the complexity of its neural network during training. It starts with a small, simple version of an image and slowly adds details and resolution over time. This approach helps the system learn more stable and high-quality images, such as faces or objects. By focusing on simpler features first and then refining, PGGAN produces highly detailed, convincing images that can be hard to distinguish from real photos.
