Dunnhumby is almost mythical in some circles. The company’s work with UK retailing giant Tesco led to the development of an early loyalty card scheme, and some pretty impressive mining of trends from the data that shoppers handed over every time the card got swiped at a checkout. Now Dunnhumby is using Kaggle to offer developers access to some of that lovely data… and a $10,000 prize for putting it to work. All that the winner has to do is analyse data from 100,000 customers in order to successfully predict when each of those customers will next visit a store, and how much they’ll spend. Easy, huh? Retail, like Manufacturing, is one of those industry segments sitting on a wealth of good data, just waiting for the right tools and processes to come along.
