Google tried to prove that big data analytics can predict the spread of the flu, and it was hailed with fanfars all around the world when they published an HR article in 2008 or 2009. The algorithm failed because it fine-tooted on the past and couldn't know that. It didn't do well, and then the silently without fun far buried it. So I'm just writing a book on machine learning and fast and frugal heuristics,. focusing on fast and fudgetal trees and so on.
