Here are my codes for an epileptic seizure prediction (a kaggle competition). you can find the MATLAB code that I wrote for this competition: Melbourne University AES/MathWorks/NIH Seizure Prediction
In this competition I became 6th on the public leader-board but then 25th on the private one. It was due to the fact that competition's scores were computed by AUC in a very weird way : a single AUC for 3 different patients… Anyway.. it was a fun competition full of opportunities to learn.
