Neural Networks for Machine Learning

This is an online course from the University of Toronto.  If you can spend about 8 hours a week for 8 weeks you should be thoroughly familiar with ANN's.

Learn about artificial neural networks and how they're being used for machine learning, as applied to speech and object recognition, image segmentation, modeling language and human motion, etc. We'll emphasize both the basic algorithms and the practical tricks needed to get them to work well.
