— Yoshua Bengio, Advances in Neural Information Processing Systems

Adversarial training is a technique that can be used to improve the robustness of generative models. In adversarial training, the generative model is trained to generate data that is indistinguishable from real data, while a discriminator model is trained to distinguish between real data and data generated by the generative model. The adversarial training process helps to improve the realism of the data generated by the generative model and makes it more difficult to distinguish between real data and data generated by the generative model.

The curse of dimensionality is a phenomenon where the amount of data required to accurately model a system grows exponentially with the number of dimensions.
