주의
When you create a mining model, Analysis Services chooses a subset of attributes to include in the data mining model based on statistical analysis. This attribute reduction process is called feature selection. The method for feature selection differs depending on the algorithm. For more information, see 기능 선택(데이터 마이닝).
Feature selection can be applied to both input and output attributes. If you have many attributes, in a nested table, for example, it is possible that not all of the attributes will be included in the final model. Therefore, you can call the MiningModel method to determine which attributes are selected for input only, which attributes are selected for output only, and which attributes are selected for both output and input. You can also return all attributes or attributes that have no feature selection value.
