Read me, touch me 23 August 2001 WHAT IS NNW, NAME AND CONTENT NNW is an acronym of Neu (neural) Net Work. It is a product of a new form of thinking about Neural Networks. HOW DOES NNW WORK NNW works different from other Neural Networks. Originally Neural Networks were based on ideas of Donald Hebb 1950. Subtle changing the synapses and so the connections between neurons giving thinking was the principle of traditinal Neural Networks. In contrast we know that our brains work with: --1. is there a connection, 2. yes? fine, 3. go on.-- There is more to do. This demo is based on that simple idea. WHERE TO GET IT You can download the NNW source from the NNW website (http://nnw.sourceforge.net). To compile it you need GTK >= 1.2 too. I guess it'll work with version 1.0 too, but I did not try it, and you probably have to change something. Get GTK from your linux distribution, a bit new one has GTK included, look in the documentation of your linuxdistributor up how to install it. Alternatively you can download the GTKsource the GTK homepage, http://www.gtk.org. You also need GCC (or any other C++ compiler, NNW is written in C but uses C++ style comments) and GNU make (or compatible). You can get both from http://www.gnu.org. HOW TO COMPILE AND INSTALL NNW Download the tarball nnw-0.03.tar.gz and possibly some other required software from the appropiate websites, and unpack them in a directory of your choice, usually /usr/local/src. To get information about how to compile and install the other software, please consult the INSTALL or README files in the root of the appropiate source directories. After installing the required software (most people will not need to install much other software, maybe the gtk1.2 libs and development libs of their linux distribution, change to the directory where NNW is unpacked. I take /usr/local/src/nnw-0.03 here. Edit Makefile to suit your configuration (you probably don't need to change much). After that run 'make'. This will create some object files and an executable 'nnwgui'. You can delete the object files with 'make clean'. To remove the binary, the nnnet data files, logs and backups run 'make distclean'. To uninstall just remove the directory where you placed NNW. USING THE NNW DEMO To run NNW change to the directory where it's located and run nnwgui, usually with './nnwgui' from a Xterm under X. You can also start it from a filemanager like kfm or gmc, but you'll not see any messages then. When you run ./nnwgui you see appearing only a small column of knobs. First you can clear the NN and start at the position yet nothing learned. The second knob is learning the alphabet. After that you can view the network. After each choice you can view. Other choices are dozing and sleeping. A view can be enlarged in the normal way. Close the views yourself. In a laborious way you can alter the input file snnslet and run the program. There are three 'snnslet' files included: snnslet1 contains only capital letters (A-Z) snnslet2 contains only numbers (0-9) snnslet3 contains both capital letters and numbers, note that the 0 is one row lower here, to prevent the 0 from conflicting with O You can just copy (or symlink) one of the files to snnslet, by default is snnslet equal to snnslet1. This way of installing and running NNW works already on different machines in my neighborhood. NNW is an open source project under GPL. NON GTK If you want to compile the program without the gtk functions then add the parameter GTK=no to make. You can always run the non gtk version so in textmode version with alt-main. PATTERNS The included patterns program can convert normal text to snnslet patterns, that could be used in nnwshop. The code to really recognize patterns isn't there yet (the character is possibly recognized, but the output format should be equal to the input format, normal text again). You can test it by running './pattern infile outfile' where infile is a file containing the defined characters (look in patterns.c for more info), and outfile is the file where the snnslet patterns will be written to. Please look in patterns.c for more information, but please consider that this is work in progress, it's not yet integrated with nnwgui & stuff.
