One of my professors was working on a PHD research project involving predicting soccer match outcomes using a neural net. At that time it was very...wrong...but I wonder if he ever made any progress towards better accuracy.
Inaccurate would probably be a better word. The results were fairly inconsistent, and for whatever reason he decided that he wanted to bet real money before perfecting (or at least as best as possible) the predictions and he lost a lot of money haha
