Data Characteristic Reporting and Modeling Tuning Recommendation

Disclosed is a method for providing data characteristic reporting and modeling tuning recommendations.

DemandTec

        ® Retail Solution provides retailers with optimal pricing recommendations, which is built on a statistical model. The Modeling Service Statisticians are the users of this model, who run the model, validate the model, and release the model. The model is controlled by a list of settings, different run values of which will potentially generate different model fits, good or bad, based on characteristics of the data. While there's not an automatic detecting system for the best values of those modeling settings, statisticians have to wait for the completion of the model to examine the results and decide the modeling settings that need to be tuned. Yet the implementation of such tuning needs to be done via another round of remodeling effort. For example, a modeling option called "USE_CLUSTERS" (store clustering), is an option to aggregate store level data to cluster level data, such that the model could generate more reliable estimation off of richer data. This method can be leveraged to deal with data sparsity. However, there's lack of a way to automatically detect the data sparsity before a modeling job is run. Therefore, Statisticians have to go through several iterations and then decide whether clustering is necessary for a model.

Utilizing the disclosed method, the system can detect the sparsity issue based on the data characteristics beforehand and suggest using store clustering for a particular category, which could save a lot of statistician efforts as well as modeling iterations.

The following steps are performed:
Recycle the information as useful input for tuning modeling option. Take modeling setting "USE_CLUSTERS" for example, DB2* queries may be used
