Some time ago there was a little bit more traffic in this newsgroup and a neural network program named bpsim was posted by Richard Caasi (Oct. 87) which was written in C and demonstrated a small example of the back-propa- gation algorithm. This program and the idea behind it is explained in an article by William P. Jones and Josiah Hoskins "Back-Propagation" in BYTE Vol. 12, No. 11 August 1987 p. 155-162. J. Hoskins is also the author of the program. I did draw a copy of this program - but I weren't very lucky in compiling it using Turbo-C. It worked once and a while, though I'm not sure that it wasn't subtly spoiled in the transfer. I am no "C-Crack" and didn't want to bother people who are. Maybe some of the above mentioned "listens" and repost the program (wasn't so big, about 16KB) together with some instruction to activate under Turbo-C. I have the source available, but I don't know if I have the right to post it. There is another introductory article and a program listing in C in Dr.Dobb's Journal #126 April 1987 by Robert Jay Brown "An Artificial Neural Network Experiment". The program simulates an "adaptive template matching image categorizer". It "learns to recognize (visual) patterns by being trained from a set of prototype patterns presented in a training file". I didn't have the time to "hack" it into my PC, maybe someone else has and kindly posts it to this newsgroup? Hope this is some new information to you. -- Thomas -- !
