84.51 Builds a Machine Learning Machine for Kroger

Machine learning is a great way to extract maximum predictive or categorization value from a large volume of structured data. The idea (at least for "supervised learning," by far the most common type in business) is to train a model on a one set of labeled data and then use the resulting models to make predictions or classifications on data where we don't know the outcome. The approach works well in concept, but it can be labor-intensive to develop and deploy the models. One company, however, is rapidly developing a "machine learning machine" that can build and deploy very large numbers of models with relatively little human intervention. You may have heard of dunnhumby, a UK-based analytics company that's owned by the big retailer Tesco.
