Readings

This area is moving very fast and the textbooks are not up-to-date. Some recommended readings:

  • Neural Networks and Deep Learning An online book by Michael Nielsen, pitched at an appropriate level for 10-601, which has a bunch of exercises and on-line sample programs in Python.

For more detail, look at the MIT Press book (in preparation) from Bengio - it's very complete but also fairly technical.

Things to remember

  • The underlying reasons deep networks are hard to train
    • Exploding/vanishing gradients
    • Saturation
  • The importance of key recent advances in neural networks:
    • Matrix operations and GPU training
    • ReLU, cross-entropy, softmax
