A 2D display or simply display is always part of the user interface. It serves to display the network topology, the units' activations and the weights of the links. Each unit is located on a grid position, which simplifies the positioning of the units. The current position, i.e. the grid position of the mouse, is also numerically displayed at the bottom of the manager panel. The current version displays units as boxes, where the size of the box is proportional to the value of the displayed attribute.
Possible attributes are activation, initial activation, bias, and output.
A black box represents a positive value, an empty box a negative value. The size of the unit varies between 16x16 and 0 pixels according to the value of scaleFactor . The parameter scaleFactor has a default value of , but may be set to values between and in the setup panel. Each unit can be displayed with two of several attributes. One above the unit and one below the unit.
