Clamped Neuron
Clamped
neurons will not change their value as a network runs, though their
value can be set by the user (using the random button, the up /
down arrows, or the edit dialog). They can be used to provide a
fixed source of input to other neurons.
Tip: Clamped nodes are often
useful for the input layer of a network that will be tested in the
GUI. It is often useful to set the adjustment increment of a
clamped neuron to a value that makes it easy to quickly change clamped
activations using the up/down keys.
