The Public Domain Neural Network (PDNNET) is for newcomers to neural nets and focuses on the essentials of backpropagation neural nets. Once PDNNET has helped you to understand neural nets, you can graduate to more advanced commercial packages some of which are found in Appendix B of the User's Manual. PDNNET implements a backpropagation neural network that omits momentum. Its TURBO C 2.0 source code (PDNNET.C), User's Manual (MANUAL.DOC), and examples are included. The manual also describes neural nets in general, has an example application, a bibliography, list of information/software resources, and presents a mathematical development of backpropagation. To run, simply type PDNNET and respond to the prompts.
