Classifier Model Filters
You can apply filters to classifier model data in the default and detailed views.
You can use filters to perform the following tasks:
- •Find data values that do not have an associated label. Use the label options to filter the data rows that display in a classifier model. If a data row does not use a label, add a label to the row.
- •Find data values in reference data rows. Use the filter in the default view to find data values in the reference data. Verify that the reference data overlaps with the source data in a mapping.
- •Find a data value within a reference data row. Use the filter in the detailed view when you need to verify that a reference data row contains a data value. A data row can contain a large quantity of data values.
Finding Values in Reference Data
Use the filter in the default view to verify that reference data rows contain the data values you expect.
1. Open the content set that contains the model.
2. Select the model name and click Edit.
3. Type a text value in the filter field.
The Developer tool displays the data rows that contain the filter text.
Finding Data Rows with no Labels
Clear all label options to display the reference data rows that do not have a label.
When you open a classifier model, the Developer tool displays all rows and labels by default.
1. Open the content set that contains the model.
2. Select the model name and click Edit.
3. In the default view, select or clear a label.
When you select a label, the model displays the data strings that you associated with the label. When you clear a label, the model hides the data strings that you associated with the label.
4. To verify that all data strings use a label, clear all the label values. The model displays any string that does not use a label.
5. Click a label value to add the label to the data string.
Finding a Value in a Data Row
Use the filter in the detailed view to search for a data value in a single data row.
1. Open the content set that contains the model.
2. Select the model name and click Edit.
3. Select the detailed view.
4. In the default view, enter a value in the filter field.
The model displays the data rows that contain the value.
5. Select a data row to search.
6. Type the search value in the search field below the data row.
The model highlights the first instance of the value in the row.
7. Click the Down arrow to find the next instance of the value in the row.
Use the Up and Down arrows to move through the values in the data row.
