How to: Adjust Algorithm Parameters
You can tune the algorithms that are provided in Microsoft SQL Server Analysis Services by using algorithm parameters.
For More Information:Data Mining Algorithms (Analysis Services - Data Mining)
To change an algorithm parameter
- On the Mining Models tab of Data Mining Designer in Business Intelligence Development Studio, right-click the algorithm type of the mining model for which you want to tune the algorithm, and select Set Algorithm Parameters. - The Algorithm Parameters dialog box opens. 
- In the Value column, set a new value for the algorithm that you want to change. - If you do not enter a value in the Value column, Analysis Services uses the default parameter value. The Range column describes the possible values that you can enter. 
- Click OK. - The algorithm parameter is set with the new value. The parameter change will not be reflected in the mining model until you reprocess the model.
