Class InputLayer

java.lang.Object

org.cognity.neural.layer.InputLayer

All Implemented Interfaces:

Serializable, Layer

public final class InputLayer
extends Object
implements Layer, Serializable

Input layer is a layer which provides data for other layers. It doesn't perform any computations. The input of this layer is always equal to it's output.

Constructor Detail

InputLayer

public InputLayer(int neuronCount)

Creates a new input layer with specified number of neurons.

Parameters:

neuronCount - the number of neurons in 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.

stimulate

public void stimulate(int neuron,
             double value)

Sets input and output of specified neuron to the given value.

Specified by:

stimulate in interface Layer

Parameters:

neuron - the index of the neuron

value - the value

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

activate

public void activate()

Doesn't do anything.

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
