Class Activation

java.lang.Object

org.aika.Activation

All Implemented Interfaces:

Comparable<Activation>

public class Activation
extends Object
implements Comparable<Activation>

The Activation class is the most central class in Aika. On the one hand it stores the activation value for a given neuron in the State substructure. On the other hand it specifies where this activation is located within the document and to which interpretation it belongs. The Activation.Key therefore consists of the logic node to which this activation belongs. If this logic node is an or-node, then this activation automatically also belongs to the neuron as well. Furthermore, the key contains the char range within the document and the relational id (rid). The relational id might be used to store the word pos for instance. Lastly, the key contain the interpretation node of this activation, specifying to which interpretation this activation belongs. The activations are linked to each other on two levels. The fields inputs and outputs contain the activation links within the logic layer. The fields neuronInputs and neuronOutputs contain the links on the neural layer.
