  • New to SQL Server 2008
    • Microsoft_Time_Series algorithm improved
      • now includes ARIMA in addition to the existing ARTxp method, and a blending algorithm is now used to deliver more accurate and stable predictions, both short and long term, from a hybrid model. In addition, a new prediction mode allows you to add new data to time series models.
    • Holdout Support added
      • You can easily partition your data into training and test sets that are stored in the mining structure and are available to query after processing.
    • Ability to build mining models based on filtered subsets added
      • (e.g. just male customers), this means that you no longer have to create multiple mining structures and re-read the source data for such variations over a dataset
    • Drillthrough functionality extended
      • makes all mining structure columns available, not just columns included in the model
      • allows you to build more compact models without sacrificing the ability to producing actionable output reports like targeted mailing lists.
    • Cross-validation added
      • allows users to quickly validate their modeling approach by automatically building temporary models and evaluating accuracy measures across K folds. The feature is available through a new cross-validation tab under Accuracy Charts in Business Intelligence Development Studio, in addition to being accessible programmatically via a stored procedure call.
  • Summary
    • Data Mining in SQL Server 2008 is mature, powerful and accessible
    • Can use Excel 2007
      • Familiar client for BI – OLAP cubes AND Data Mining models
