Info Panel

    The info panel displays all data of two units and the link between them. The unit at the beginning of the link is called SOURCE, the other TARGET. One may run sequentially through all connections or sites of the TARGET unit with the arrow buttons and look at the corresponding source units and vice versa.

This panel is also very important for editing, since some operations refer to the displayed TARGET unit or ( SOURCE TARGET) link. A default unit can also be created here, whose values (activation, bias, IO-type, subnet number, layer numbers, activation function, and output function) are copied into all selected units of the net.

The source unit of a link can also be specified in a 2D display by pressing the middle mouse button, the target unit by releasing it. To select a link between two units the user presses the middle mouse button on the source unit in a 2D display, moves the mouse to the target unit while holding down the mouse button and releases it at the target unit. Now the selected units and their link are displayed in the info panel. If no link exists between two units selected in a 2D display, the TARGET is displayed with its first link, thereby changing SOURCE.

In table the various fields are listed. The fields in the line FUNC have the following meaning (from left to right): Name of the activation function, name of the output function, name of the f-type. The fields in the line LINK have the following meaning: weight, site value, site function, name of the site.

  
Table: Table of the unit, link and site fields in the Info panel

Unit number, unit subnet number, site value, and site function can not be modified.

  Note: The specified SNNS value ranges must be obeyed. Values outside the specified range are not rejected by the graphical user interface. Numerical values of the type float have the following format: Sign, one digit, decimal point, and five decimal digits. For bias and weight two digits before the decimal point are critical. To change attributes of type text, the cursor has to be exactly in the corresponding field.

There are the following buttons for the units (from left to right):

1. Arrow button xgui_figs/xgui_button_first.ps: Select first TARGET of SOURCE (arrow button at TARGET) or select first SOURCE of the TARGET (arrow button at SOURCE).

2. Arrow button xgui_figs/xgui_button_next.ps: Select next TARGET of SOURCE (arrow button at TARGET) or select next SOURCE of the TARGET (arrow button at SOURCE).

3. : Unit is frozen, if this button is inverted. Changes become active only after is clicked.

4. : The default unit is assigned the displayed values of TARGET and SOURCE assigned (only activation, bias, IO-type, subnet number, layer numbers, activation function and output function).

5. : Calls the following menu:

   

6. : Only after clicking this button the attributes of the corresponding unit are set to the specified value. The unit is also redrawn. Therefore the values can be changed without immediate effect on the unit.

There exist the following buttons for links (from left to right):

1. xgui_figs/xgui_button_first.ps: Select first link of the TARGET unit.

2. xgui_figs/xgui_button_next.ps: Select next link of the TARGET unit.

3. : Calls the following menu:

   

4. : Only after clicking this button the link weight is set.
