Neural Networks Package

Revision History

June 21, 1999

Original reslease of my ANN package.

July 1, 1999

Added FeedForwardSCG class. Vastly superior to back propogation for solution speed.

Added getSlope() method to Neuron and BasicNeuron classes so that network training algorithms can be independent of neuron type.

Major revisions to comments throughout the package for improved clarity and documentation.

Fixed a bug in the FeedForwardBP class that prevented training if the network had more than one hidden layer.

December 5, 1999

Cleaned up some comments.

Made neurons and feed forward networks serializable so they can be saved to disk and restored from disk.

Fixed minor bug in XOR demo program.

Package now requires Java 1.1 or later.

August 11, 2002

Added Hyperbolic Tangent Neuron type provided by Dimitri Pissarenko.

Cleaned up code and comments a bit. Removed last vestiges of the formatting added by an old code generator that I was using.
