Dunnhumby's Shopper Challenge

better predict when supermarket shoppers will next visit the store and how much they will spend.

Going grocery shopping, we all have to do it, some even enjoy it, but can you predict it?
Dunnhumby is looking to build a model to better predict when supermarket shoppers will next visit the store and how much they will spend.
The modelling data set consists of details of every visit made by 100,000 customers over a year from April 2010 to March 31st 2011.
Each visit is stamped with the date and the customer's spend in that visit.
We also have details of their next visit after March 31st.
Your challenge is to predict the visit_date and visit_spend of this next visit for each customer_id in the modelling test set. For more details on how you're scored, click here

There are 54 mb of training data in zip format, 4.6 MB of test data.

Competition start: 29 July 2011
Competition end: 11:59 pm, Friday 30 September 2011 UTC
