It is possible to experiment with the methods using various data distributions and observe the learning process. A common terminology is used to make it easy to compare one method to the other. Thanks to the Java programming language the implementations run on a very large number of platforms without the need of compilation or local adaptation. Hopefully, the experimentation with the models will increase the intuitive understanding and make it easier to judge their particular strengths and weaknesses.<P></P><P><P><BR><HR><!--Table of Child-Links--><A NAME="CHILD_LINKS"> </A><UL><LI><A NAME="tex2html12" HREF="node1.html#SECTION00010000000000000000">Contents</A><LI><A NAME="tex2html13" HREF="node2.html#SECTION00020000000000000000">List of Figures</A><LI><A NAME="tex2html14" HREF="node3.html#SECTION00030000000000000000">1 Introduction</A><LI><A NAME="tex2html15" HREF="node4.html#SECTION00040000000000000000">2 System Requirements</A><LI><A NAME="tex2html16" HREF="node5.html#SECTION00050000000000000000">3 Installation</A><LI><A NAME="tex2html17" HREF="node6.html#SECTION00060000000000000000">4 Starting the Java Applet</A><LI><A NAME="tex2html18" HREF="node7.html#SECTION00070000000000000000">5 Manual</A><UL><LI><A NAME="tex2html19" HREF="node8.html#SECTION00071000000000000000">5.1 Network Model</A><LI><A NAME="tex2html20" HREF="node9.html#SECTION00072000000000000000">5.2 Drawing Area</A><LI><A NAME="tex2html21" HREF="node10.html#SECTION00073000000000000000">5.3 General Options</A><UL><LI><A NAME="tex2html22" HREF="node11.html#SECTION00073100000000000000">5.3.1 Buttons</A><LI><A NAME="tex2html23" HREF="node12.html#SECTION00073200000000000000">5.3.2 Checkboxes</A><LI><A NAME="tex2html24" HREF="node13.html#SECTION00073300000000000000">5.3.3 Pull-Down Menus</A></UL><LI><A NAME="tex2html25" HREF="node14.html#SECTION00074000000000000000">5.4 Model Specific Options</A><UL><LI><A NAME="tex2html26" HREF="node15.html#SECTION00074100000000000000">5.4.1 LBG<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif">, LBG-U</A><LI><A NAME="tex2html27" HREF="node16.html#SECTION00074200000000000000">5.4.2 Hard Competitive Learning<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif"></A><LI><A NAME="tex2html28" HREF="node17.html#SECTION00074300000000000000">5.4.3 Neural Gas<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif"></A><LI><A NAME="tex2html29" HREF="node18.html#SECTION00074400000000000000">5.4.4 Competitive Hebbian Learning<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif"></A><LI><A NAME="tex2html30" HREF="node19.html#SECTION00074500000000000000">5.4.5 Neural Gas with Competitive Hebbian Learning<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif"></A><LI><A NAME="tex2html31" HREF="node20.html#SECTION00074600000000000000">5.4.6 Growing Neural Gas<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif">, Growing NeuralGas with Utility<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif"></A><LI><A NAME="tex2html32" HREF="node21.html#SECTION00074700000000000000">5.4.7 Self-Organizing Map<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif"></A><LI><A NAME="tex2html33" HREF="node22.html#SECTION00074800000000000000">5.4.8 Growing Grid<IMG WIDTH="49" HEIGHT="38" ALIGN="BOTTOM" BORDER="0" SRC="../smallDuke.gif"></A></UL></UL><LI><A NAME="tex2html34" HREF="node23.html#SECTION00080000000000000000">6 Wishlist</A><LI><A NAME="tex2html35" HREF="node24.html#SECTION00090000000000000000">References</A><LI><A NAME="tex2html36" HREF="node25.html#SECTION000100000000000000000">7 Change log</A></UL><!--End of Table of Child-Links--><BR><HR><ADDRESS><I>Hartmut S.
