This selection displays a successfully built Support Vector Machine (SVM) regression model.
The model viewer has three tabs as follows:
The Settings tab is displayed by default.
The settings tab displays the Type of the model
This selection displays the settings used to build the selected Support Vector machine (SVM) classification or regression model.
The Type of the model (Classification or Regression), the Algorithm (Support vector machine), and the Target Attribute are displayed. The Sequence ID is also displayed. Sequence ID identifies the key column; this field is displayed if a key column identifier is defined. A key column is required for text mining.
The following algorithm settings are displayed:
For detailed information about the settings, see SVM Classification Settings or SVM Regression Settings.
The attributes are displayed in the Attributes grid; the following information is displayed for each attribute:
NUMBER
, FLOAT
, CHAR
, VARCHAR2
, etc.To save the attributes information as a text file, click the Save As icon (a yellow arrow above a graphic of a page) above the Attributes grid.
This tab lists the coefficient value for specific target value and attribute value pairs. The coefficients represent SVM and NMF model details. To see the coefficients, click the Coefficients tab.
Select a Target Class value for which to display coefficients using the pulldown list. For a binary classification problem, coefficients are displayed for only one value of the target. For a multi-class classification problem, coefficients are displayed for all values of the target.
The Bias is displayed in a read only field. Bias is a constant that is added to the model predictions to reflect the scale in its original input data. Bias is used in all SVM models (both regression and classification).
The coefficients are displayed in the Coefficients grid. If you want coefficients sorted by absolute value so that, for example, -0.5 is listed just before +0.5, click the Sort coefficients based on absolute value check box.
The following information is displayed:
To save the attributes information as a text file or a spreadsheet, click the Save As icon (a yellow arrow above a graphic of a page) above the Attributes grid.
The following buttons are displayed:
To see results, click the Results tab.
The tab contains a tree view of results. To view specific results, select the result and click View. To delete a result, select one or more results and click Delete.
This tab describes the task used to build the model. It shows when the task ran and what input data was used.
