%description
Generative Adversarial Networks are applied to generate generative data
for a data source. A generative model consisting of a generator and a
discriminator network is trained. During iterative training the
distribution of generated data is converging to that of the data source.
Direct applications of generative data are the created functions for data
classifying and missing data completion. A software service for
accelerated training of generative models on graphics processing units is
available. Reference: Goodfellow et al. (2014)
