Summary
Generative adversarial networks are a very active area of research today. They belong to the family of generative models, which includes RBM and deep belief networks.
Generative models aim at generating more data, or learning better features for supervised and other tasks in an unsupervised way.
Generative models can be conditioned on some environmental input, and try to find the hidden variables behind the real data.
These models, the most advanced, complete the overview of deep learning nets with Theano. The next chapter will look at some advanced concepts to extend Theano and the future of deep learning.
