Constructor Detail

WeightlessSynapse

public WeightlessSynapse()

Simple default constructor.

WeightlessSynapse

public WeightlessSynapse(Layer fromLayer,
                         Layer toLayer)

Construct a weighted synapse between the two layers.

Parameters:

fromLayer - The starting layer.

toLayer - The ending layer.

Method Detail

clone

public Object clone()

Specified by:

clone in interface Synapse

Specified by:

clone in class BasicSynapse

Returns:

A clone of this object.

compute

public NeuralData compute(NeuralData input)

Compute the weightless output from this synapse. Each neuron in the from layer has a weightless connection to each of the neurons in the next layer.

Parameters:

input - The input from the synapse.

Returns:

The output from this synapse.

createPersistor

public Persistor createPersistor()

Return a persistor for this object.

Returns:

A new persistor.

getMatrix

public Matrix getMatrix()

Description copied from interface: Synapse

Get the weight matrix.

Returns:

null, this synapse type has no matrix.

getMatrixSize

public int getMatrixSize()

Description copied from interface: Synapse

Get the size of the matrix, or zero if one is not defined.

Returns:

0, this synapse type has no matrix.

getType

public SynapseType getType()

Returns:

The type of synapse that this is.

isTeachable

public boolean isTeachable()

Returns:

False, because this type of synapse is not teachable.

setMatrix

public void setMatrix(Matrix matrix)

Attempt to set the matrix for this layer. This will throw an error, because this layer type does not have a matrix.

Parameters:

matrix - Not used.
