Class InputNode

java.lang.Object

org.aika.lattice.Node

org.aika.lattice.InputNode

All Implemented Interfaces:

Comparable<Node>, Writable

public class InputNode
extends Node

The InputNode class is the input layer for the boolean logic. The input-node has two sources of activations. First, it might be underlying logic node of an InputNeuron in which case the input activations come from the outside. The second option is that the activation come from the output of another neuron.
