The importance of early feedback on new product launches

Grocery stores are always looking to introduce new products, such as a new flavor of drink, a new type of yogurt, or the latest DVD.  In the highly competitive world of retailing, the success or failure of these new product launches is highly dependent on the first few weeks of sales.  The earlier you know how well the product launch is doing, the earlier you can decide whether you want to increase advertising and the number of stores selling the product, or whether you cut your losses on a product that is doomed to fail.

The mission:  Predict how successful each of a number of product launches will be 26 weeks after the launch, based only on information up to the 13th week after the launch.

The data:  In order to create and train your forecasting models, we will provide a training set which includes the information for the full 26 weeks, for around 3000 product launches. For the challenge, the data set will contain 1000 product launches over 13 weeks, and we ask that you predict the number of units sold for each of these launches in week 26. We have reduced the data to a modelling set of tens of thousands of rows in order for the participants to focus on the predictive modelling rather than preparing the data.

The training set and question set each contain by week for each launch:

  • The category of the product, such as Bread, Coffee or Video Games
  • The number of stores selling the product (note that this for all 26 weeks in the question set rather than just the first 13 weeks)
  • The number of units sold that week
  • The number of distinct customers who have bought the product (cumulative)
  • The number of distinct customers who have bought the product at least twice (cumulative)
  • Cumulative units sold to a number of different customer groups:  Convenience at home, Family Focussed, Finest, Grab and Go, Shoppers On A Budget, Traditional Homes, Watching the Waistline, Least Price Sensitive, Price Sensitive, Splurge and Save, and Very Price Sensitive

Who should attend?  

Individuals with a passion for data science, data modeling, and statistics. Participants are welcome to form teams or work individually for this competition. 

How will I know how well I’m doing?
We will be using the Kaggle platform for this competition, making it easy to know your ranking throughout the day. 

What if I have a question?
Domain and data experts will be on hand to answer any questions that you have, just let us know! 

And, of course, who wins?
We will score each of your predictions based on how close you are to the actual result. An exact prediction scores you the maximum 100 points, and the further you are away from the correct prediction, the less points you score. We sum your scores across all the launches, and whoever scores the most wins! 

We have $4,000 in cash prizes and $1,000 in gift cards to distribute across the first, second, and third place winners! 

Data hackers, we look forward to your participation!

This event brought to you by dunnhumby and hack/reduce, in partnership with Kaggle.
Please direct any questions you may have to info@hackreduce.org.
