This repository presents the basic notions that involve the concept of Generative Adversarial Networks.

"...the most interesting idea in the last 10 years in ML". Yann LeCun

Generative Adversarial Networks or GANs is a framework proposed by Ian Goodfellow, Yoshua Bengio and others in 2014.

GANs are composed of two models, represented by artificial neural network:

• The first model is called a Generator and it aims to generate new data similar to the expected one.
• The second model is named the Discriminator and it aims to recognize if an input data is ‘real’ — belongs to the original dataset — or if it is ‘fake’ — generated by a forger.
