Filtering Parameters

When viewing parameter information on the Parameters tab in the Design Gateway, you can filter the data to make it more useful to your design process.

1. From the Design Gateway, select a model.

2. Select the component, and click the Parameters tab.

3. Click the button above the parameter list.

   The Table Filters dialog box appears.

4. Determine how you want to filter the parameters:

   Option	Description
   Name	Select this option to filter the parameters based on the parameter name. Tip: To filter just by the parameter name, you can enter text in the Name text box (located above the parameter list). You can use the “*” wildcard with the Name filter. For more information, see About Parameter Names.
   Display Name	Select this option to filter parameters based on the name that appears in visuals (e.g., graphs, correlation maps, etc.). You can use the “*” wildcard with the Display Name filter. For more information, see About Display Names.
   Mode	Select this option to filter the parameters based on the mode (Input, Output, Input/Output, or Local). Tip: To filter parameters just by the Mode, you can enter the mode type in the Mode list (located above the parameters list). For more information, see About the Parameter Mode.
   Value	Select this option to filter the parameters based on the parameter values.
   Unit	Select this option to filter the parameters based on the unit. For more information, see About Units.
   Type	Select this option to filter the parameters based on the type (Boolean, Integer, Real, or String).
   Description	Select this option to filter the parameters based on the parameter description. You can use the “*” wildcard with the Description filter.
   Allowed Values	Select this option to filter the parameters based on the allowed values (the values that this parameter can be set to when the corresponding component executes). For more information, see About Allowed Values.
   Mapped	Select this option to filter the parameters based on whether or not they are mapped.
   Save to DB	Select this option to filter the parameters based on whether or not the values for the parameter are saved to the results database. If this option is not selected, parameters that are not saved will not be displayed on the Parameters or History tabs in the Runtime Gateway during and after execution. For more information, see Setting Gateway Preferences.

5. Click OK to save your changes and to close the Table Filter dialog box.

   Isight updates the Parameters tab based on your filter selections. Any column selected as part of your filter options displays the icon to the left of the column header. The text to the right of the button shows you how many parameters (rows) match your filter based on the total number of parameters (rows).

6. Perform any of the following actions, as desired:

   • Add to the existing filter by clicking the button.

   • Remove the defined filter, and return the parameter list to its original state, by clicking the button.

7. Save the model, if desired.

You can use the Runtime Gateway Data Filter to filter the history of runs for the selected component, which reduces the amount of information displayed and can allow you to better analyze the execution data. Filtering can be based on the desired minimum/maximum parameter values included and/or based on the “grading” of the runs using the problem formulation (lower/upper bounds, objectives).

The filtered data set is displayed on the Parameters, History, Data Analysis, and Graphs tabs. However, postprocessing graphs from the process components (e.g., the Main Effects graphs for DOE) use the full, unfiltered data set even after filtering.

1. From the Runtime Gateway, access one of the following tabs:

   • Parameters
   • History
   • Data Analysis
   • Graphs

2. Verify that you are viewing the parameters for the desired component. If not, select the correct component using the model explorer.

3. At the bottom of the tab, click Data Filter.

   The filtering options appear.

   The Data Filter options are divided by input and output parameters. Parameter information is displayed in the Data Filters tables near the bottom of the tab.

4. Change the Min and Max values for the desired input and output parameters. The initial minimum and maximum values are set from the range of the full data set. The data set presented in the Runtime Gateway for the selected component is dynamically altered after each change to the minimum and maximum values. The number of data points currently presented is displayed at the top of the Data Filters table.

5. Click Options, and perform any of the following actions to further filter your data:

   • To control the filtering based on the minimum/maximum values of parameters in the data set, use the following options:

     Option	Description
     Activate min/max filters	Filters the data set using specific minimum/maximum values of parameters in the data set and selectively turns off/on the filtering without losing the defined minimum/maximum values.
     Show active min/max only	Displays only parameters whose defined minimum/maximum values have resulted in data points being filtered in the Data Filters tables.
     Clear all min/max filters	Returns all min/max values to the minimum/maximum values from the full data set (removing all min/max filtering).

   • To control the filtering based on the grading of the runs using the problem formulation, use one of the following mutually exclusive options:

     Option	Description
     Show feasible and infeasible	Shows runs whether they are feasible (meet all defined lower/upper bounds) or infeasible (violate at least one lower/upper bound).
     Show feasible only	Shows only those runs that do not violate any lower/upper bounds on parameters as defined in the problem formulation.
     Show infeasible only	Shows only those runs that violate at least one lower/upper bound on a parameter as defined in the problem formulation.

   • Click Show improvements only to show only those runs that are considered “improvements” over all previous runs with respect to any defined objectives (and satisfaction of constraints) in the problem formulation.

   • Click Show exact runs only to exclude all approximation runs (if you used an approximation in your model).

   • Click Show Pareto Points to display only the Pareto points in your design. By default, all points of the selected component are displayed. Selecting this option filters out all non-Pareto data points so that only the Pareto solutions are shown. Although this option is available for all components, the computed Pareto set is closest to the true Pareto set only when multi-objective optimization techniques (i.e., AMGA, Multi-Objective Particle Swarm, NCGA, and NSGA-II) are used.

   • Click Apply Filters to all Postprocessing to control whether or not filters are used in all of the postprocessing tools (including graphs, tables, and data analysis tools). By default, this option is not enabled, and any filtering or feasibility options that are in use are ignored when a postprocessing tool is used. Selecting this option causes postprocessing tools (including computing a Pareto set) to use only the data provided after using the filtering and feasibility options.

     Note: This option is not available when using the Six Sigma component’s Reliability Technique analysis type.

   • Click Filter by distance to control the filtering based on the Euclidean distance from a target. The Euclidean distance is calculated in a space where the ranges for all parameters are normalized to [0, 1] using the maximum and minimum values from the history.

     1. In the Filter by Distance dialog box, enter the Filter Target values for the parameters. By default, Isight uses the target values set in the problem formulation.
     2. Enter the Number of rows to display. By default, the value is 0. Leaving this value at 0 shows all the runs in the history.

        When targets are set for filtering, a new column labeled Filter Distance appears in the History table. To sort the rows based on the filter distance, click the column heading. The Filter Distance column is omitted when you export the data to Excel or to a text file.

6. From the Runtime Gateway, select View Run to view values from different runs for the current job.

7. From the Runtime Gateway, click Run Directory to select and view any file in the associated working directory if any files were saved with the job and you are running the job locally.
