NeuralCAD - Version 2.3 A program that enables the user to create 4 different types of neural networks: Counterpropagation, Backpropagation, Brain-State-in-a-Box, and Discrete Autocorrelator. Also included in this version is the ability to save the networks and Help support. The fully registered version of NeuralCAD includes printing support and two additional networks: Fuzzy Associative Memory and Boltzmann Machine. The program requires the user to have some knowledge of neural networks. In addition, NeuralCAD v2.3 includes the ability to choose from 6 different threshold functions for the Backpropagation neural network.
