Configure Convex Hull on Inputs

In/Outputs menu >Hull on Inputs

Or

In the optimization windows: Hull (2D) button.

The Convex Hull on Inputs is a bound around the training data. This bound can be considered in the optimization, so that optimization results stay inside the range of the training data.

The Configure Convex Hull on Inputs window contains the following elements:

All pairwise convex 2D-Hulls checkbox

If activated (default), 2D hulls for all input pairs are used. The Show button next to the checkbox opens a Closedscatter plot window that shows all pairwise 2D hulls.

Table area

This area allows the specification of user-defined hulls.

Column

Meaning

Active

The checkboxes activate/deactivate the hulls.

Invisible until the first dimension is selected.

1st Dimension

You must select at least two dimensions to define a hull. A third and/or fourth dimension are optional.

Each drop-down list offers all inputs for selection, and a "-" to leave out inputs for the respective dimension.

Note  

Duplicate inputs in a hull are forbidden.

2nd Dimension

3rd Dimension (optional)

4th Dimension (optional)

5th Dimension (optional)

Deletes the respective hull.

Invisible until the first dimension is selected.

Show

Opens a Closedscatter plot window that shows all 2D and 3D combinations of the selected inputs.

Invisible until the first dimension is selected.

A new empty row appears when the first dimension is selected in a row.

A row disappears if you click its button, or if you deselect the last input.

OK

Applies your settings and closes the window.
