Subject: The Neural Graphics Neural Network Simulator. In order to keep up with the number of requests we have had for the NG software package, the code has been placed in the public directories here at AFIT. WHAT IT IS: A neural network simulator package with graphics for backprop (several flavors), radial basis functions, higher order nets, error surface demonstrations and a few other things. It runs on silicon graphics machines, and unix machines without graphics. A smaller version run on a PC-AT (or better) WHO IT'S FOR: Any one who teaches neural networks for class room demonstration, or anyone who want to come up to speed quickley on the differences between the different paradigms, run up simple test problem, ect. Its probably not as fast and flexible as, Zell's (German) package. Or the Rochester system. But its a lot easier to use, and cheaper than Neuralware. HOW TO GET IT: Use ftp on your local machine with ftp blackbird.afit.af.mil Respond to the prompts. user: anonymous password: just type in your local user id. The files you want are tarrtar.Z,tar_doc.Z (compressed) or tarr2tar, and NeuHelp.ps. (uncompressed). HOW TO UNPACK IT. For the compressed code: type uncompress tarrtar ect, then tar -xvof tarrtar (the flags mean:x -> extract,v-> verbose,o-> owner (very important) f -> take from a file, not the tape drive) Next get into the directory neural (which you just created) and examine the makefile. Comment out the library flags which dont correspond to your machine. The default is a SG 4D or personal iris. Next get the documentation, and send it to your favorite postscript printer. If you have any problems, give me a call (513-255-9918) or email gtarr@blackbird.afit.af.mil. WHAT TO DO NEXT. Read the documentation. Examine the data files (*.dat,*.data) examine a file called README and setup.fil. Send us comments. gtarr@blackbird.afit.af.mili. If you use the code I would appriciate at least an Email note so I can keep track of how the package is being used (Thanks in advance) for further updates. PC Version: We have a PC version available. Transfer from the public directory a file called tarrtar.exe. The file is a self-extracting zip file. To unpack, Put the file on your hard disk where you want the code. Type the dos command "NG.exe -d". Then type the command "net". You must have at least an AT and training times are not very reasonable without a math coprocessor. WARNINGS As you must understand, the code is offered as shareware. There is no warrenty, expressed or implied. The package is only intended to illustrate concepts of neural network learning. No software package is ever completely bugfree. Neither AFIT nor the AUTHORS are responsible for any problems, you may have. License Agreement * Copyright (c) 1 January 1991, Gregory L.
