Class SineLayer

java.lang.Object
  org.joone.engine.Layer
      org.joone.engine.SimpleLayer
          org.joone.engine.SineLayer

All Implemented Interfaces:

java.io.Serializable, java.lang.Runnable, Learnable, LearnableLayer, NeuralLayer, Inspectable

public class SineLayer
extends SimpleLayer
implements LearnableLayer

The output of a sine layer neuron is the sum of the weighted input values, applied to a sine (sin(x)). Neurons with sine activation problems might be useful in problems with periodicity.
