Class AndNode

network.aika.lattice.AndNode

All Implemented Interfaces:

Comparable<Node>, Writable

public class AndNode
extends Node<AndNode,AndActivation>

The InputNode and the AndNode classes together form a pattern lattice, containing all possible substructures of any given conjunction. For example if we have the conjunction ABCD where A, B, C, D are the inputs, then the pattern lattice will contain the nodes ABCD, ABC, ABD, ACD, BCD, AB, AC, AD, BC, BD, CD, A, B, C, D. The pattern lattice is organized in layers, where each layer only contains conjunctions/patterns of the same size. These layers are connected through refinements. For example the and-node ABD on layer 3 is connected to the and-node ABCD on layer 4 via the refinement C.

Method Detail

propagate

protected void propagate(AndActivation act)

Description copied from class: Node

Propagate an activation to the next node or the next neuron that is depending on the current node.

Specified by:

propagate in class Node<AndNode,AndActivation>

delete

public void delete(Set<String> modelLabels)

Specified by:

delete in class AbstractNode<Provider<AndNode>>

cleanup

public void cleanup()

Specified by:

cleanup in class Node<AndNode,AndActivation>

changeNumberOfNeuronRefs

public void changeNumberOfNeuronRefs(int threadId,
                                     long v,
                                     int d)

Overrides:

changeNumberOfNeuronRefs in class Node<AndNode,AndActivation>

reprocessInputs

public void reprocessInputs(Document doc)

Specified by:

reprocessInputs in class Node<AndNode,AndActivation>

remove

public void remove()

Overrides:

remove in class Node<AndNode,AndActivation>

logicToString

public String logicToString()

Specified by:

logicToString in class Node<AndNode,AndActivation>

write

public void write(DataOutput out)
           throws IOException

Description copied from interface: Writable

Serialize the fields of this object to out.

Specified by:

write in interface Writable

Overrides:

write in class Node<AndNode,AndActivation>

Parameters:

out - DataOuput to serialize this object into.

Throws:

IOException

readFields

public void readFields(DataInput in,
                       Model m)
                throws IOException

Description copied from interface: Writable

Deserialize the fields of this object from in.

For efficiency, implementations should attempt to re-use storage in the existing object where possible.

Specified by:

readFields in interface Writable

Overrides:

readFields in class Node<AndNode,AndActivation>

Parameters:

in - DataInput to deseriablize this object from.

Throws:

IOException
