Data Pair Outlier Filter


The Data Pair Outlier Filter separates any data pairs whose elements do not fall within specified bounds. The data pairs whose elements fall within the bounds are passed through the right output port. The other elements are passed through the bottom output port.

Configuring

To set the upper and lower bounds for each element, use the configure command. NOL displays this configuration panel:


To specify the number of elements of each vector, enter the dimensions for the data pair's x and y vectors in the Number of Inputs and Number of Targets attributes, respectively.

To edit the input vector's bounds, select the Edit Input Bounds button. To edit the target vector's bounds, select the Edit Target Bounds button. NOL displays a spreadsheet for editing the input and output bounds.

Here are the spreadsheets for editing the x and y bounds of a data pair with two inputs and 1 target:


The editor has two columns: Lower and Upper bounds. When you enter the bounds, the Upper bounds must always be greater than the Lower bounds. Therefore, you must enter the values in a specified order.

When you are done editing the bounds, click the OK button in the spreadsheet and edit the other dimension. Click the OK or Apply button in the configuration panel when you are finished.

For more information on how to use the spreadsheet, see "Using the GXL Spreadsheet to Edit Data".

Making Values Permanent

When you choose make permanent from the block's menu, the block saves the filter's upper and lower bounds.

Example

In the example below, the Data Pair Outlier Filter takes data pairs from a Data Pair Buffer. It passes data pairs that fit into its bounds to the In-Bounds Data Set and the rest to the Out-of-Bounds Data Set.


These spreadsheets show the bounds for the Data Pair Outlier Filter above.
