Constructor Detail

Data

public Data()

Creates new Input

Data

public Data(int conn,
            int exam)

Create a new empty Data object with specified number of connections and examples.

Each connection represents an input or an output. E.g., for a network with 10 inputs and 3 outputs would need a Data object with 10 connections for its input. The output from the network will be a Data object with 3 connections.

Parameters:

conn - The number of connections

exam - The number of examples

Data

public Data(double[][] d)

Create a new Data object from an array of an array of double.

It is assumed that the first index of the array corresponds to the connections and the second index corresponds to the examples.

Parameters:

d - The data
