Generative Models

• GAN : http://kvfrans.com/generative-adversial-networks-explained/
• VAE : http://kvfrans.com/variational-autoencoders-explained/
  • autoencoder와 동일하나 latent vector를 생성할 때 (unit) gaussian으로만 생성하도록 constraint를 줌. 그래서 unit gaussian random variable로부터 generate.
  • In practice, there's a tradeoff between how accurate our network can be and how close its latent variables can match the unit gaussian distribution.
  • latent vector를 바로 만들지도 않고 mean, std만 만들어낸다.
