Abstract: Provided are a method and apparatus for neutral network training and a method and apparatus for image generation. The method includes that: a first random vector is input to a generator to obtain a first generated image; the first generated image and a first real image are input to a discriminator to obtain a first discriminated distribution and a second discriminated distribution; a first network loss of the discriminator is determined based on the first discriminated distribution, the second discriminated distribution, a first target distribution and a second target distribution; a second network loss of the generator is determined based on the first discriminated distribution and the second discriminated distribution; and adversarial training is performed on the generator and the discriminator based on the first network loss and the second network loss.
