Class FIRFilter

java.lang.Object

org.joone.engine.FIRFilter

All Implemented Interfaces:

java.io.Serializable

public class FIRFilter
extends java.lang.Object
implements java.io.Serializable

Element of a connection representing a FIR filter (Finite Impulse Response). The DelaySynapse object implements a delayed full synapse where each connection is implemented with a FIRFilter object. In this connection is implemented the temporal backpropagation algorithm by Eric A. Wan, as in 'Time Series Prediction by Using a Connectionist Network with Internal Delay Lines' in Time Series Prediction. Forecasting the Future and Understanding the Past, by A.Weigend and N.Gershenfeld. Addison-Wesley, 1994.
