This selection displays a successfully built Naive Bayes (NB) model, one kind of classification model.
For a brief description of NB, see Naive Bayes Algorithm.
The following menus appear when the model is displayed in a new window:
The model viewer has the following tabs:
This tab displays the Type of the model (Classification), the Algorithm used to build the model (Naive Bayes), the Algorithm Settings used to build the model, the Target Attribute for the model, and the Attributes used to build the model.
Oracle Data Mining 11g models can be built using Automatic Data Preparation (ADP). If the model was built using ADP, then Automatic Data Preparation has the value yes
.
The following algorithm settings are displayed:
For information about these thresholds, see Naive Bayes 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 or a spreadsheet, click the Save As icon (a yellow arrow above a graphic of a page) above the Attributes grid.
This tab lists the pair probabilities, the probability value for a specific attribute value and target value combination. The pair probabilities represent the Naive Bayes model details.
For each value of the target, the following information is displayed:
AGE
, Value is 25, and Probability is 0.8, then both the target=0 and AGE
=25 are true 80% of the time.Data for an NB model build is discretized (binned). If the bin table is available, Bin is available. Click Bin to use bin values in the rules; click Unbin to use unbinned values. The default is to use unbinned values.
To filter the information displayed in the table, click Filter. You can specify particular attributes, maximum and minimum probabilities, and the order in which the results are displayed.
To save the attributes information as a text file, click the Save As icon (a yellow arrow above a graphic of a page) next to Filter.
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, what input was used, and what output was created.
