> Given any big amount of data you are going to find something that fits Exactly, and that's the main problem at the base of all "data mining": it is probable that you will find a model that will only work with your data. Take a step outside and everything falls. You are basically giving a formula to noise. But often discoveries happen also by chance, so we shouldn't stop looking at unexpected patterns. However, once you find one, you should create a theory to explain it and setup a new experiment to confirm your theory. If you can....
