生成的敵対的ネットワーク（GAN）
生成的敵対的ネットワーク（GAN）は 深層学習フレームワーク introduced by Ian Goodfellow and his colleagues in 2014. It consists of two ニューラルネットワーク: the generator and the discriminator, which are trained simultaneously through a process of competition.
ジェネレーターは 新しいデータ instances, such as images, by learning from a training dataset. Its goal is to produce data that is indistinguishable from real data. Conversely, the discriminator evaluates the data it receives, determining whether it is real (from the training set) or fake (produced by the generator).
During training, the generator improves its output based on feedback from the discriminator, while the discriminator becomes better at detecting fakes. This adversarial process continues until the generator produces data that the discriminator can no longer reliably distinguish from genuine data. As a result, GANs can generate highly realistic images, audio, and other types of content.
GANは、アート生成を含むさまざまな分野で応用されています。 画像の強化, video game design, and even drug discovery. However, they also pose challenges, such as mode collapse, where the generator produces limited varieties of outputs, and the need for large datasets for effective training.
