= Generative Stochastic Network =

• A simple implementation of GSN according to (Bengio et al., 2013)

= Convolutional Neural Network =

• A naive implementation (purely using Matlab)
• Pooling: max (Jonathan Masci's code) and average
• Not for serious use!

• Parallel Tempering
• DBN: Up-down Learning Algorithm

= Deep Boltzmann Machine =

• Binary/Gaussian Visible Units + Binary Hidden Units
• (Persistent) Contrastive Divergence
