Constructor Detail

GenericTransferLayer

public GenericTransferLayer(int neuronCount,
                    Function transferFunc)

Creates a new layer with specified number of neurons and transfer function.

Parameters:

neuronCount - the number of neurons in the layer

transferFunc - the activatoin function of the layer

Method Detail

getNeuronCount

public int getNeuronCount()

Description copied from interface: Layer

Returns the number of neurons in this layer.

Specified by:

getNeuronCount in interface Layer

Returns:

the number of neurons in this layer.

getInput

public double getInput(int neuron)

Description copied from interface: Layer

Returns the value of net input of the specified neuron.

Specified by:

getInput in interface Layer

Parameters:

neuron - an index of the neuron in this layer

Returns:

the value of the input of the specified neuron

getOutput

public double getOutput(int neuron)

Description copied from interface: Layer

Returns the value of the output of the specified neuron.

Specified by:

getOutput in interface Layer

Parameters:

neuron - an index of the neuron in this layer

Returns:

the value of the output of the specified neuron

setTransferFunc

public void setTransferFunc(Function function)

Description copied from interface: TransferLayer

Sets the transfer function for this layer.

Specified by:

setTransferFunc in interface TransferLayer

Parameters:

function - the transfer function

getTransferFunc

public Function getTransferFunc()

Returns the activation function of this layer.

Specified by:

getTransferFunc in interface TransferLayer

Returns:

the activation function of this layer

getBias

public double getBias(int neuron)

Description copied from interface: TransferLayer

Returns the bias value of the specified neuron.

Specified by:

getBias in interface TransferLayer

Parameters:

neuron - the index of the neuron

Returns:

the bias value

setBias

public void setBias(int neuron,
           double value)

Description copied from interface: TransferLayer

Sets the bias value for the specified neuron.

Specified by:

setBias in interface TransferLayer

Parameters:

neuron - the index of the neuron

value - the bias value

stimulate

public void stimulate(int neuron,
             double value)

Stimulates specified neuron with the given value. All stimuli is summed up and form the neuron's input.

Specified by:

stimulate in interface Layer

Parameters:

neuron - the index of the neuron

value - the stimulation value

activate

public void activate()

Description copied from interface: Layer

Performs calculations for this layer. Calling this method updates inputs and outputs of neurons.

Specified by:

activate in interface Layer

init

public void init(LayerInitializer initializer)

Description copied from interface: Layer

Initializes this layer using the provided initializer. This is a visitor-pattern method, the implementation should only call initializer.init(this).

Specified by:

init in interface Layer

Parameters:

initializer - the initializer

toString

public String toString()

Overrides:

toString in class Object
