The http://deeplearning.net/ http://deeplearning.net/ is a go to website for beginners. You would find everything from datasets to experiment to tutorials. This subject requires a lot of match and ML background though and would need sometime to catch up to the latest research. Coding part will involve GPU code if you want to go truely in with large data sets. If you want to just apply the algorithms to specific problem without diving deep in to its theory there are few kits available in Python and C++. There a tech talks and other videos on tutorial page that might be good starting point.
