Method Details

createPerceptron

public Perceptron createPerceptron(Activation activation,
 double bias)

Creates a Perceptron in this Layer with a specified activation function and bias.

Parameters:

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

bias - A double which specifies the initial value for the bias weight.

createPerceptron

public Perceptron createPerceptron()

Creates a Perceptron in this Layer of the neural network. The created Perceptron uses the logistic 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. The created Perceptrons use the logistic activation function and have an initial bias value of zero.

Parameters:

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

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 the specified bias.

Parameters:

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

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

bias - A double containing the initial value to be applied as the bias values for the Perceptrons.

Returns:

An array containing the created Perceptrons.
