org.neuroph.core.input.InputFunction

 Neuron's input function. It has two subcomponents: weightsFunction - which performs operation with input and weight vector summingFunction - which performs operation with the resulting vector from weightsFunction InputFunction implements the following behaviour: output = summingFunction(weightsFunction(inputs)) Different neuron input functions can be created by setting different weights and summing functions.
