Understanding Neural Networks with Theano

Submitted Apr 10, 2017

Theano is not only a powerful tool to build and run deep and shallow neural networks, it is also a wonderful learning resource. Since it works primarily on symbolic mathematical expressions, it can help us understand how learning in neural networks can be interpreted in terms of equations, vectors, variables and Python functions.

In this tutorial, participants will get a (very) brief background on the mathematics of neural networks and how to use theano to convert this knowledge into a Python program that can train and use a neural network.

Broadly the topics covered will be as follows:

  1. Constructing simple neural networks in Python
  2. Vectorizing neural networks in NumPy
  3. Simplifying the neural network construction with Theano
  4. Extending simple neural networks into deep networks

Outline

The workshop will proceed with four different Jupyter notebooks, each of them highlighting and providing exercises on different aspects of neural networks. The details can be found here:

Requirements

  1. Intermediate knowledge of Python - classes, functions, control statements
  2. Basic knowledge of the numpy.ndarray object
  3. Basic differential calculus
