Method Detail

createPerceptron

public Perceptron createPerceptron(Activation activation,
                                   double bias)

Creates a Perceptron in this Layer with a specified Activation and bias.

Parameters:

activation - The Activation object which specifies the action function to be used.

bias - A double which specifies the initial value for the bias for this Perceptron.

createPerceptron

public Perceptron createPerceptron()

Creates a Perceptron in this Layer of the neural network. By default, the created Perceptron uses the linear activation function and has an initial bias value of zero.

createPerceptrons

public Perceptron[] createPerceptrons(int n)

Creates a number of Perceptrons in this Layer of the neural network. By default, they will use linear activation and a zero initial bias.

Parameters:

n - An int which specifies the number of Perceptrons to be created in this layer.

Returns:

An array containing the created Perceptrons.

createPerceptrons

public Perceptron[] createPerceptrons(int n,
                                      Activation activation,
                                      double bias)

Creates a number of Perceptrons in this Layer with specified activation and bias.

Parameters:

n - An int which specifies the number of Perceptrons to be created.

activation - The Activation object which indicates the action function to be used.

bias - A double which specifies the initial bias for the Perceptrons.

Returns:

An array containing the created Perceptrons.

getNodes

public Node[] getNodes()

Return the Perceptrons in the OutputLayer.

This method overides the method in Layer to return the Perceptrons in an OutputPerceptron array.

Overrides:

getNodes in class Layer

Returns:

An OutputPerceptron[] array containing the Nodes in the OutputLayer.
