Operations
Just like Analysis Services cubes, we need to reprocess mining models to train them with new input data. There is no "incremental process" option with mining models, however, so you need to reprocess using the full data set.
The product recommendations model probably needs to be reprocessed on a regular basis so that it is kept current with the latest products and sales trends. In our e-commerce solution, the model is reprocessed on a weekly basis and then copied from development into the Web production environment. The customer segmentation model will be used for marketing processes such as organizing marketing campaigns that take some time to complete, so the model will not be reprocessed often.
| Tip: Reprocessing Mining Models Drops Cluster Names |
Another reason that the customer segmentation model is not reprocessed often is that the carefully selected cluster names such as Defector and Newbie are replaced with the default Cluster 1 and Cluster 2 names during processing. This is also important to know during development when you are designing your model, because you will be losing any cluster names every time you need to change anything in the model.
