You start by feeding both neural networks a whole lot of training data and give each one a separate task. The first network, known as the generator, must produce artificial outputs, like handwriting, videos, or voices, by looking at the training examples and trying to mimic them. The second, known as the discriminator, then determines whether the outputs are real by comparing each one with the same training examples.<\/p>\n<p id=\"27a5\" class=\"hq hr du bh hs b ht hu hv hw hx hy hz ia ib ic id\" data-selectable-paragraph=\"\">Each time the discriminator successfully rejects the generator\u2019s output, the generator goes back to try again.
