Data Mining in Cube Space

  • Data cube greatly increases the analysis bandwidth
  • Four ways to interact OLAP-styled analysis and data mining
    • Using cube space to define data space for mining
    • Using OLAP queries to generate features and targets for mining, e.g., multi-feature cube
    • Using data-mining models as building blocks in a multi-step mining process, e.g., prediction cube
    • Using data-cube computation techniques to speed up repeated model construction
      • Cube-space data mining may require building a model for each candidate data space
      • Sharing computation across model-construction for different candidates may lead to efficient mining
