Class StaticNeuronLayer

java.lang.Object

NearNeural.NeuronLayer

NearNeural.StaticNeuronLayer

public class StaticNeuronLayer
extends NeuronLayer

The Static Neuron Layer holds only Static neurons, that is those without any Edges. This allows this layer and its accompanying neurons to be used as an input layer. It supports the changing of node values directly, so that input can quickly be changed without the overheads of clearing and recreating the Edges and array elements related to other layers which may depend on the members of this layer.

Static layers cannot back-propogate

Constructor Detail

StaticNeuronLayer

protected StaticNeuronLayer(int p_numberOfNeurons,
                 ThresholdingAlgorithm p_thresholdModel)
                     throws ValueOutOfBoundsException

Creates a new layer with a given number of Static Neurons. Since all of these neurons will be without edges they are simply created apart from any other layers, and given a default values of 0.5, which will result in 0 on a sigmoid net.

Parameters:

p_numberOfNeurons - The number of Static neurons to create in this layer

Throws:

ValueOutOfBoundsException

Method Detail

setInputValue

protected void setInputValue(double p_value,
                 int p_index)
                      throws IndexOutOfBoundsException,
                             ValueOutOfBoundsException

Sets the input value of one static node.

Parameters:

p_value - The value to set a stupid Neuron to

p_index - The index of the Neuron of which to set the value

Throws:

IndexOutOfBoundsException

ValueOutOfBoundsException

setInputValues

protected void setInputValues(double[] p_values)
                       throws IndexOutOfBoundsException,
                              ValueOutOfBoundsException

Sets all nodes in this layer to the values given, in order.

Parameters:

p_values - The set of values to which to set the nodes

Throws:

ValueOutOfBoundsException - if provided values exceed the 0<x<1 bounds required of this net

IndexOutOfBoundsException - if not enough or too few values are provided to set the input Neurons
