Awesome Machine Learning Applications

Spam filtering is passe. We need better application examples. Put them here!

How about, adaptive machine learning algorithms for detection of discrete brainwave signatures in OpenEEG brain-data?

• User puts headset on, and computer recognizes whos brainwaves its getting
• detect event-correlated-potentials, and specific distinguishable discrete brainwave-patterns unique to users
