All Implemented Interfaces:

Comparable<Node>, Writable

public class OrNode
extends Node<OrNode,OrActivation>

While several neurons might share a the same input-node or and-node, there is always a always a one-to-one relation between or-nodes and neurons. The only exceptions are the input neurons which have a one-to-one relation with the input-node. The or-nodes form a disjunction of one or more input-nodes or and-nodes.

                             NodeActivation inputAct)

propagate

protected void propagate(OrActivation 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<OrNode,OrActivation>

cleanup

public void cleanup()

Specified by:

cleanup in class Node<OrNode,OrActivation>

reprocessInputs

public void reprocessInputs(Document doc)

Specified by:

reprocessInputs in class Node<OrNode,OrActivation>

delete

public void delete(Set<String> modelLabels)

Specified by:

delete in class AbstractNode<Provider<OrNode>>

changeNumberOfNeuronRefs

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

Overrides:

changeNumberOfNeuronRefs in class Node<OrNode,OrActivation>

logicToString

public String logicToString()

Specified by:

logicToString in class Node<OrNode,OrActivation>

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<OrNode,OrActivation>

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<OrNode,OrActivation>

Parameters:

in - DataInput to deseriablize this object from.

Throws:

IOException

getNeuronLabel

public String getNeuronLabel()

Overrides:

getNeuronLabel in class Node<OrNode,OrActivation>

setOutputNeuron

public void setOutputNeuron(Neuron n)

getOutputNeuron

public Neuron getOutputNeuron()
