Field Detail

activationOnThreshold

protected double activationOnThreshold
When a processing unit's activation value is above this threshold, the circle representing it will be drawn in red. Units between the activationOnThreshold and activationOffThreshold display the background color.

activationOffThreshold

protected double activationOffThreshold
When a processing unit's activation value is above this threshold, the circle representing it will be drawn in blue. Units between the activationOnThreshold and activationOffThreshold display the background color.

weightThreshold

protected double weightThreshold
When a connection weight's value is less than -1 times the weightThreshold, the line connecting its units is drawn in blue. When the weight is greater than the weightThreshold, the line is drawn in red. If outside inside the threshold, no line is drawn.
