DEEP LEARNING TUTORIALS
Deep Learning is a new area of Machine Learning research, which has been introduced with the objective of
moving Machine Learning closer to one of its original goals: Artificial Intelligence. See these course notes
for a brief introduction to Machine Learning for AI and an introduction to Deep Learning algorithms.
Deep Learning is about learning multiple levels of representation and abstraction that help to make sense of
data such as images, sound, and text. For more about deep learning algorithms, see for example:
• The monograph or review paper Learning Deep Architectures for AI (Foundations & Trends in Ma￾chine Learning, 2009).
• The ICML 2009 Workshop on Learning Feature Hierarchies webpage has a list of references. • The LISA public wiki has a reading list and a bibliography. • Geoff Hinton has readings from 2009’s NIPS tutorial.
The tutorials presented here will introduce you to some of the most important deep learning algorithms and
will also show you how to run them using Theano. Theano is a python library that makes writing deep
learning models easy, and gives the option of training them on a GPU.
The algorithm tutorials have some prerequisites. You should know some python, and be familiar with
numpy. Since this tutorial is about using Theano, you should read over the Theano basic tutorial first. Once
you’ve done that, read through our Getting Started chapter – it introduces the notation, and [downloadable]
datasets used in the algorithm tutorials, and the way we do optimization by stochastic gradient descent.
The purely supervised learning algorithms are meant to be read in order:
1. Logistic Regression - using Theano for something simple
2. Multilayer perceptron - introduction to layers
3. Deep Convolutional Network - a simplified version of LeNet5
The unsupervised and semi-supervised learning algorithms can be read in any order (the auto-encoders can
be read independently of the RBM/DBN thread):
• Auto Encoders, Denoising Autoencoders - description of autoencoders
• Stacked Denoising Auto-Encoders - easy steps into unsupervised pre-training for deep nets
• Restricted Boltzmann Machines - single layer generative RBM model
• Deep Belief Networks - unsupervised generative pre-training of stacked RBMs followed by supervised
fine-tuning

Deep Learning Tutorial, Release 0.1
Building towards including the mcRBM model, we have a new tutorial on sampling from energy models:
• HMC Sampling - hybrid (aka Hamiltonian) Monte-Carlo sampling with scan()
Building towards including the Contractive auto-encoders tutorial, we have the code for now:
• Contractive auto-encoders code - There is some basic doc in the code.
Recurrent neural networks with word embeddings and context window:
• Semantic Parsing of Speech using Recurrent Net
LSTM network for sentiment analysis:
• LSTM network
